Dry Ice Smoke Machine? The 192 Top Answers

The level of detail that goes into wedding planning these days is amazing. From flowers to decoration and entertainment to party favors. A question we always hear when planning the first dance is dry ice or smoke machine? In this blog, we’ll walk you through what we think are the pros, cons, and our recommendation!

The fog machine

Let’s start with the smoke machine. This device is generally a much cheaper option. However, we see that as the only real benefit. But is the low price really an advantage? The type of smoke this one puts out is generally warmer, meaning the smoke rises quickly. This will generally set off fire alarms in your venue and make some guests cough. If you’re looking to book this device you’ll need to let your venue know, where they usually charge a hefty fee to isolate the alarm during your first dance. Also, the smoke isn’t as thick and doesn’t fill the room as much.

The dry ice machine

This device works by putting dry ice inside the machine where it meets hot water. This blend creates a thick cloud-like effect. Due to the use of dry ice, the cloud is much colder, allowing it to remain at ground level throughout the first dance. The dry ice then also evaporates at ground level, preventing it from triggering alarms. This saves you from having to organize the isolation of the alarm, which also eliminates these extra costs. The clouds with this device are also much more extravagant and are the choice of most weddings.

our recommendation

If the cost between these two devices is keeping you from making your decision, you should consider the actual effect each produces and the additional costs that may be involved (delivery fee, operator costs, isolating alarms). Our choice in this case is the dry ice machine! If you aim for ‘spectacular’ then this unit ticks all the right boxes – this is a hit and will definitely wow your guests!

We are often asked what is the difference between these three special effects machines. So we thought we’d put this quick guide together to explain what the main differences are and what machine you should use to get the effect you want.

SMOKING MACHINE

Smoke machines, also known as smoke machines, use a special liquid to produce thick white smoke to create an impressive visual effect. They often come with a remote control to control the amount of smoke produced as well as the duration. Fog machines produce a similar effect to low fog machines, however, the heated smoke produced by fog machines rises and disperses throughout the room, while low fog machines produce cold liquid particles and the fog stays close to the ground.

Input: smoke liquid

Exit: smoke

Particles: smoke

Use smoke machines for: shows, concerts, parties, scary effects. Use it when you want the whole room to be smoky and not just the floor (low smoke machine).

LOW FOG MACHINE

A low-level fog machine (similar to dry ice machines) creates a dense, opaque fog that stays close to the ground to create a “walking-on-air” effect. Fog machines create this effect by cooling liquid onto liquid particles. A low fog machine will typically produce an intense burst of fog rather than a more subtle diffusion like a hazer. The effect of a low fogger is similar to that of a fog machine – both are designed to create a visual effect/impression, while a haze machine is designed to emphasize other effects such as beams of light or lasers.

There are two main types of low fog machines:

A dry ice machine – this uses solid dry ice and water. It’s a simpler method but doesn’t have the runtime of the cryogenic machine.

A cryogenic machine – this uses a liquid such as liquid CO2 gas and has a longer lasting effect.

Input: dry ice or liquid CO2 gas (depending on machine type)

Exit: low-lying fog

Particles: liquid droplets

Use low level smoke machine for: Weddings (especially for the first dance), shows, theaters, Halloween parties.

HAZE MACHINE

Haze machines, also known as “hazers”, can be oil or water based and are used to complement lighting effects. Haze machines produce a fine and subtle haze with long ‘hang time’ – the particles remain in the air for a long time before dissipating, making them ideal for use at shows and concerts. They produce a much more subtle and less noticeable effect than smoke or fog machines because they are designed to emphasize the lighting effects, allowing you to see rays and patterns that you would not normally see.

Input: fog liquid

Output: fine mist/haze

Particles: liquid droplets

Use haze machines for: shows, concerts, festivals and anywhere you want to emphasize lighting effects or create a foggy atmosphere. Perfect if you don’t want the thick, opaque effect of a smoke machine or smoke machine.

With each of these machines, there is a big difference between the cheaper versions and the professional machines. If you want quality, reliable performance at your event, go for the latter. This doesn’t necessarily mean you have to pay more, but you definitely get better value for your money. Professional machines usually have a continuous automatic cycle, which means they can work continuously without having to stop.

A woman died in Washington after being exposed to dry ice fumes in a “horrific accident,” according to news reports.

The 77-year-old woman was found dead in a car with several containers of dry ice on July 27, according to local news agency KOMO. The car belonged to the woman’s son, an ice cream vendor who kept four coolers of dry ice in the back of the vehicle. The man’s wife had borrowed the car to drive the woman, her mother-in-law, home.

But when the man found his wife and mother unconscious in the car, he called 911. The mother died, believed to have died of asphyxiation from the dry ice fumes, and the woman is in critical condition.

“Somehow … the fumes escaped from the radiators,” said Ed Troyer, a spokesman for the Pierce County Sheriff’s Department.

“At this point, we just consider this a horrific accident,” Troyer told local news outlet The News Tribune.

Dry ice is known for the spooky looking vapor it produces, which isn’t usually dangerous. But in rare cases it can be fatal.

Dry ice is the solid form of carbon dioxide and has a freezing point of minus 109 degrees Fahrenheit (minus 78 degrees Celsius). When dry ice melts, it goes through a process called sublimation, which turns the solid directly into a gas, according to the Centers for Disease Control and Prevention (CDC). If dry ice is stored in an area without adequate ventilation, it can cause people to inhale large amounts of the gas CO2, which displaces oxygen in the body, according to the CDC. This, in turn, can lead to harmful effects, including headaches, confusion, disorientation, and death.

Although rare, such cases have occurred before. In 2004, the CDC reported a case of a man who passed out while driving in his car with several bags of dry ice that he had bought to keep groceries cool in the event of a power outage following Hurricane Ivan. The man’s wife found him unconscious in the car, but he woke up when she opened the door.

In the new case, officials said several things likely went wrong that caused the woman’s death. For example, the ice cream vendor had recently bought a new car that likely had better sealing and less ventilation, which was trapped in the fumes, Troyer said. “It was a combination of things that went horribly wrong,” Troyer told KOMO.

Dry ice poisoning cases occur worldwide and have been reported from countries such as Germany, Japan, Thailand, Switzerland and the United States. Accidents involving handling dry ice also include frostbite or damage caused by the explosion of cargo containers. This BfR statement focuses on the risk of poisoning.

The term “dry ice” refers to solid carbon dioxide (CO2) that is cooled to at least -78.5°C. At room temperature, dry ice is converted into gaseous CO2 by sublimation. This is accompanied by a sharp increase in pressure with a risk of explosion in airtight containers. The gaseous CO2 released by dry ice can cause asphyxiation. Because the CO2 displaces the oxygen in the air, for example in poorly ventilated rooms or during transport in vehicles. This reduces the oxygen content of the inhaled air. At the same time, the absorption of oxygen in the red blood cells in the lungs is also reduced. High concentrations of CO2 in the air we breathe can lead to an insufficient supply of oxygen to the brain or body tissues. From simple headaches, at levels greater than about 2 percent CO2, symptoms can include sweating, shortness of breath, palpitations, shortness of breath, fainting, blurred vision, tremors, and impaired consciousness. At concentrations of more than 5 percent in the breathing air, CO2 has a narcotic effect. As soon as the CO2 level exceeds about 8-10 percent, unconsciousness and death by asphyxiation can occur within minutes.

The risk of dry ice poisoning increases with the amount of dry ice used, room size, and ventilation. In principle, dry ice should only be stored and transported in suitable, well-insulated containers. These containers must not be airtight (danger of explosion). Sufficient ventilation must always be ensured in closed rooms and vehicles during transport, storage and use.

General FAQs:

What is dry ice made of?

Dry ice is made from carbon dioxide. In the process of making dry ice, industry professionals subject the gas to high pressures and extremely low temperatures (109°F), forcing it to condense into its liquid form. They then inject the liquid CO2 into a block press or pelletizer, which forms it into solid blocks.

Where can I buy dry ice?

Dry ice is available at many grocery and general stores. While larger chains like Costco and Walmart likely carry it, some smaller chains may not stock it. When you contact a dry ice supplier, you get a direct and reliable source of dry ice.

How much dry ice do I need?

The amount of dry ice needed for an application depends on many factors, including product weight, packaging, and usage time. These considerations also vary based on the precise application.

For example, the amount needed to keep fresh or to freeze is different. Working with a dry ice specialist can help you determine how much dry ice is required for a specific application.

How much does dry ice cost?

Dry ice is generally priced by weight, but the exact cost varies from one retailer to the next. On average, the price ranges from $1.00 to $3.00 per pound. Some retailers also offer discounts on bulk purchases.

How long does dry ice last?

Several factors – such as packaging, air pressure, outside temperature and thickness of insulation – affect the shelf life of dry ice, making it difficult to estimate the exact duration.

Talking to a dry ice expert like the one at CryoCarb can help you determine how long your dry ice will last.

What are some of the most common uses of dry ice?

Dry ice is used in a variety of retail and commercial applications. Common use cases are:

airline catering

Clean dry ice blasting

food donation

Shipping and Fulfillment of Frozen Food

meat processing

Shipping of medical products

pharmaceutical production

research

Frequently asked questions about shipping, storage and disposal:

How is dry ice shipped?

Dry ice comes in different forms. Depending on the form requested, it can be packaged and shipped in Styrofoam coolers, ice chests ranging in size from picnic coolers to 1500 pound containers. Retail dry ice is typically placed in a small, disposable styrofoam container.

At CryoCarb we offer pellets (in both 3mm and 16mm sizes) and 5 pound blocks. Commercial shipping containers range from 200 pounds to 1,500 pounds.

How do I store dry ice?

When exposed to elevated ambient temperatures, dry ice sublimes into vapor. Although the process cannot be stopped entirely, storing the dry ice in an insulated cooler with minimal headspace in a cold area helps to slow it down. Purchasing the dry ice as close to need as possible also helps minimize the amount lost before use. Dry ice should not be stored in a refrigerator or freezer as the low temperature of the material can cause the device to turn off and/or the build up of carbon dioxide can force it open.

How do I dispose of dry ice?

When fully sublimated, dry ice leaves no waste to dispose of. Simply leave the dry ice in the cooler in a ventilated area so it can safely return to gaseous form. It should never be disposed of down the drain as it can freeze pipes.

Frequently asked questions about security:

Can I use dry ice in my food and drinks?

Dry ice is safe to use as a coolant for food and beverages. However, it should never be consumed as it can lead to serious medical problems such as internal frostbite.

What are the risks of using dry ice?

Dry ice poses serious health and safety risks. For example:

Direct skin contact with dry ice can cause instant frostbite

Dry ice ingestion can cause internal tissue damage from frostbite or fractures due to carbon dioxide buildup

Inhaling large amounts of the carbon dioxide released by sublimation can cause asphyxiation

How do I use dry ice safely?

When using dry ice, to avoid the above risks, keep the following in mind:

When handling dry ice, use gloves, tongs, and other safety equipment to avoid direct skin contact

Be aware of dry ice in consumables and limit its use when consuming alcoholic beverages

Provide good air circulation and ventilation to reduce carbon dioxide build-up in an area

Question:

Will my smoke/haze machine set off the smoke alarms at my venue?

Answers:

Possibly…

Smoke detectors are designed to detect small particles in the air using (usually) one of two methods:

Photoelectric Type – Photoelectric alarms direct a light source into a sensor chamber at an angle away from the sensor. Smoke enters the chamber and reflects light onto the light sensor; triggering the alarm.

Ionization type – these have a small amount of radioactive material between two electrically charged plates that ionize the air and allow electricity to flow between the plates.

When smoke enters the chamber, it interrupts the flow of ions, reducing current flow and activating the alarm.

Different manufacturers of smoke detectors produce different detection sensitivities – some good… some bad!

Depending on the placement of the smoke alarm installed, it WILL detect the artificial smoke/haze particles in the air…this is the smoke alarm that does a good job.

If the detector is installed farther from the point of smoke emission, there is a chance that the smoke/mist will have cleared by the time it reaches the smoke detector (or an open window/door will blow the smoke away from the detector). location)…but if the smoke doesn’t reach the detector due to airflow…then you should reconsider the current location (or number) of your smoke detection systems…you could be at fire detection risk!!!

Depending on the type of fluid you are using in your machine (use only the recommended fluid types) and low trigger levels, you may find that the smoke dissipates faster than it takes to reach the smoke detector and does not set off the alarm…or disadvantageously maybe use a liquid designed to hang around for a long time (like places within the venue you wouldn’t expect (e.g. adjacent rooms)…which will trigger detectors in different zones.

The only solution to 100% avoid triggering a smoke alarm is to turn off the detectors… BUT THIS IS NOT RECOMMENDED IF YOU DO NOT HAVE A PROPER SECONDARY FIRE DETECTION SYSTEM (SUCH AS HEAT SENSORS).

Some venues have permanently active heat detectors and a switchable smoke detection system in their main venues (other rooms are still permanently active)….where the smoke detectors are ONLY turned off during events (keeping the heat detectors on) and reset to turn back on shortly after the event (both heat and smoke detection).

CONSULT YOUR LOCAL FIRE DEPARTMENTS, BUILDING AUTHORITIES AND INSURANCE COMPANIES ETC. TO SEE WHAT SOLUTION CAN BE PROVIDED IN ACCORDANCE WITH LOCAL GUIDELINES/LAWS/RISKS REGARDING SMOKE DETECTORS/FIRE DETECTION SYSTEMS AT YOUR SITE.

**Also… Be wary of companies that state their smoke machines/liquid will not set off smoke alarms – see above for reasons why this may not be the case…

There are different types of smoke machines, but this article is about the type that uses smoke fluid and converts it into a smoke-like effect. These are commonly used in haunted houses, on dance floors, and on stages.

There are many makes and models out there so it is impossible to say if all are safe but I will explain how they work so you can determine if yours is safe and most importantly how to make it as safe as possible use possible.

A fog machine takes fog liquid, heats it until it turns into a gas, and then ejects it into the air, where it condenses into tiny droplets. So first you need a fog fluid that is pure, clean and made with quality and safe ingredients, and then you need a machine that will heat the fog fluid you have to the right temperature for that particular liquid.

Fog fluids have two main components – an active and deionized water. The active ingredient can be propylene glycol, triethylene glycol, glycerine or a mixture thereof. The vaporization temperature varies for these ingredients, so you’ll want to use a fogger that’s compatible with the liquid you have. The safest way to do this is to use the exact liquid recommended in the smoke machine instructions.

If you overheat the fog fluid, unhealthy by-products are created. If you heat the fog fluid too little, fog fluid residues will form. The first is not safe to breathe, and the second creates a slip hazard. If you’re using a well-made fog machine from a reputable manufacturer and using the fog fluid specified by the machine’s manufacturer, you shouldn’t experience any overheating or underheating.

The other safety concerns associated with the machine stem from the fact that it draws power and gets hot. You should always connect the appliance to a suitably grounded outlet and if you use an extension cord, ensure that it is rated for the wattage of the appliance. Keep flammable objects away from the machine, provide adequate space and ventilation around it, do not leave it unattended while it is hot, and—most importantly—ensure the mist is shooting into an open space and not on people or other objects. Never touch the part of the machine where the mist comes out as it is hot enough to burn your skin.

In summary, properly manufactured smoke machines are safe to use provided you:

1) Use the correct fluid for your machine, and the fluid will be fresh and clean

2) Plug your device into an appropriate outlet or extension cord and all cords and plugs are dry and in good condition

3) Be careful that the heat of the machine and the hot mist output do not touch objects that may be damaged

Device that emits a dense vapor resembling fog or smoke

A fog machine, fog generator, or smoke machine is a device that emits a dense vapor resembling fog or smoke. This artificial fog is most commonly used in professional entertainment applications, but smaller, more affordable fog machines are becoming more common for personal use. Smoke machines can also be used in a variety of industrial, educational, and some military applications. Typically, mist is created by evaporating proprietary water and glycol or glycerine-based liquids, or by atomizing mineral oil. This liquid (often colloquially referred to as fog juice) vaporizes or atomizes inside the fog machine. Upon exiting the fogger and mixing with cooler outside air, the vapor condenses, resulting in a dense visible fog.

Types [ edit ]

Heated[ edit ]

Inside view of a fog machine with pump and heat exchanger

Heated fog machines use either an inert gas or an electric pump to propel mineral oil, propylene glycol, or a mixture of glycerin and water into a heat exchanger where the solution is vaporized. Propylene glycol is used instead of ethylene glycol (i.e. antifreeze) because the latter is toxic. The most common form of heated fog machine is the pump machine. Very simple models of this type of machine consist of a fluid reservoir, an electric pump to move the fog fluid, and a heat exchanger that vaporizes the fluid. More complex models may include a variety of other features, including variable speed pumps to control fog output, timer modules, or components for remote operation and fog machine status monitoring. Some manufacturers have made accessories and liquids that, when combined with an ordinary heated pump machine, produce fog effects similar to refrigerated fog machines. Gas-powered fog machines use an inert gas (most commonly CO 2 or nitrogen) to propel either mineral oil or a glycol-based liquid into a heat exchanger, where it is vaporized into particles, creating a fog. Some models of gas powered foggers offer control over fog output by varying the volume of gas used to power the liquid.

Chilled[edit]

Cooled fog machines are designed to produce dense clouds of fog that lie low to the ground and dissipate as they rise. They are typically made using either dry ice, compressed liquid CO 2 , liquid nitrogen, or more recently liquid air.

Generic dry ice machine from a 3G. Drum.

Dry ice (solid CO 2 ) effects are created by heating water in a suitable container (e.g. a 55 gallon drum with water heating coils inside) to or near boiling point and then dropping in one or more pieces of dry ice. Because carbon dioxide is a gas at standard temperature and pressure, the carbon dioxide sublimes and instantly produces a gas, which condenses water vapor and creates a thick white fog. Liquid nitrogen (N 2 ) can be used similar to dry ice. In both cases, a fan attached to the top of the hopper directs the mist to where it is needed.

Liquid air is an alternative to using liquid nitrogen to create low-lying fog effects. Liquid air consists of N 2 and O 2 mixed in a ratio of 79% nitrogen and 21% oxygen and is stored as a liquid in insulated cylinders. This ratio of nitrogen to oxygen is the same as that of atmospheric air, and in fact liquid air can be made by simply liquefying atmospheric air. Liquid air can be used as a direct replacement for liquid nitrogen in chilled fog effects and is intended to be used in the same equipment in the same manner. Its main advantage over liquid nitrogen is that it does not pose a suffocation hazard because it contains oxygen. A disadvantage is that it supports combustion, while liquid nitrogen retards combustion.

Used[ edit ]

The versatility of fog machines makes them suitable for a wide variety of uses: fog easily helps create a certain mood or sense of a theatrical moment and is often used in plays such as Dracula, A Christmas Carol and Macbeth. Smoke machines are also commonly used in Halloween displays such as haunted houses or forests. Due to increased availability and price reductions between 2003 and 2005, smoke machines became widely available in the home for Halloween presentations. Fog machines are also useful for industrial applications, including visualization of airflow, e.g. B. to highlight drag over a surface in a wind tunnel or to test for leaks or filter effectiveness in air conditioning systems. Emergency and military services also use smoke machines in their training schedules. Because of the reflective and refractive properties of the smoke produced by fog machines, they are widely used in nightclubs and other entertainment venues to enhance the effect of lighting and laser arrays, although they are being superseded by haze machines (see also beam of light). Several companies in Europe and Canada have developed rapid-deployment smoke machines for use as intrusion and hold-up security systems, designed to disorient an intruder by filling a room with fog when triggered by a panic button or other security device. Capable of producing between 300 and 1,000 cubic meters of smoke in 30 seconds, these security smoke devices have been used in a wide range of industries, including buildings that require a high level of security, such as banks and jewellers, but also warehouses, offices and retail establishments and in cash handling chains. Concerns have been raised that these devices could cause criminals to panic, which could lead them to become violent towards customers or employees – a way to create a mantrap.[2]

Industrial uses[edit]

Ultra Low Volume (ULV) fogging is used by the pest control industry and cleaning companies. ULV refers to the droplet size (between 20-30 microns) produced by these foggers. This fine droplet size is known[3] as the optimal size for pest control. Traditional thermal fogger technology has difficulty reaching crawling pests such as cockroaches, fleas and rodents because the droplet size is too fine (less than 10 microns). Small droplets are often found to be blocked by the “air curtain” of insects and rodents. [citation needed] [3] In contrast, cold fogging is heavy enough to penetrate these “air curtains” as well as being light enough to be evenly distributed throughout the room.

Adverse health effects[edit]

Dry ice and liquid nitrogen based fog [ edit ]

Atmospheric effects created by the use of water and dry ice or liquid nitrogen can pose suffocation or breathing hazards. Both carbon dioxide and nitrogen displace normal air and the oxygen it contains, creating a risk of subtle anoxia (lack of oxygen) for people working in these atmospheres. Adequate ventilation is essential to ensure artists and technicians are surrounded by breathable air. Carbon dioxide has the additional danger of interfering with the normal breathing reflex, which is sensitive to the level of carbon dioxide in the air. Nitrogen does not affect the respiratory reflex, but this presents a hazard of its own, as a person breathing pure nitrogen can lose consciousness from lack of oxygen with no warning signs.

Liquid air mist[ edit ]

Mist generated with liquid air does not pose any carbon dioxide or liquid nitrogen hazards because the liquid air has the same composition as ordinary atmospheric air (including the same breathable oxygen content).

Fog machines that produce their effect exclusively with water, e.g. Technologies such as ultrasonic or pressure technology do not pose any particular health risks, however “water-based” fog fluid often contains glycol or glycerin.

Glycerine-based mist[ edit ]

Glycerin has a boiling point of 290°C (554°F), which is significantly higher than the temperature required to generate fog.[4] Therefore, it is unlikely that the thermostable range for glycerin will be exceeded in a normal commercial nebulization process, and therefore glycerin will not break down into other molecules due to heat at these temperatures.

Glycerin has been tested for safety in 62 tests by the National Institutes for Occupational Safety and Health (NIOSH). These tests include toxicity tests, eye irritation, skin irritation and several others.[5]

Glycol based mist[ edit ]

A number of studies have been published on the potential health effects of exposure to glycol-based theatrical and artificial fogs.

Two studies, one in 1994 by the National Institute for Occupational Safety and Health[6] and another in 2000 by the Department of Community and Preventive Medicine at Mount Sinai School of Medicine and ENVIRON Health Hazard Evaluation[7] both prepared for Actors Equity and the League of American Theaters and Producers, focused on the impact on actors and performers in Broadway musicals. The conclusion of both studies was that mucous membranes such as the eyes and respiratory tract became irritated with prolonged peak exposure to theatrical fog. The 2000 study outlined exposure guidelines which it found were intended to prevent actors from suffering adverse effects on their health or their vocal abilities.

Another study[8] focused on the use of theatrical fog in the commercial aviation industry for emergency training of personnel under simulated fire conditions. This study also found irritation to the eyes and respiratory tract.

In May 2005, a study published in the American Journal of Industrial Medicine[9] and conducted by the School of Environment and Health at the University of British Columbia examined adverse airway effects in crew members at a variety of entertainment venues, from live Theater, concerts, television and film productions to an arcade. In this study, it was found that cumulative exposure to petroleum and glycol-based mists was associated with acute and chronic adverse respiratory health effects. This study found that short-term exposure to glycol mist was associated with cough, dry throat, headache, dizziness, drowsiness, and fatigue. This study also found that long-term exposure to smoke and fog was associated with both short-term and long-term breathing problems, such as chest tightness and wheezing. Personnel working closest to the smoke machines had reduced lung function results.

The Professional Lighting and Sound Association has compiled a standard for theatrical fog or artificial fog compositions for use in entertainment venues that are “not likely to be harmful to otherwise healthy performers, technicians, or spectators of normal working age, who are 18 to 64 years of age, inclusive.” [10] This standard was based primarily (but not exclusively) on the findings of a report commissioned by the Cohen Group[11] and applies only to fog fluid compositions consisting of a mixture of water and glycol (so-called water-based fog fluid).

Short-term exposure to glycol mist can be associated with headache, dizziness, drowsiness, and fatigue. Long-term exposure to smoke and mist can be associated with upper respiratory and voice symptoms. Prolonged (multi-year) exposure to smoke and fog has been linked to both short-term and long-term respiratory health problems. Efforts should be made to reduce exposure to theatrical smoke to the lowest possible level. Using digital effects in post-production on film and television sets can be considered safer than using theatrical smoke and fog during filming, although this is not always practical.

haze machines[edit]

Haze machines, also known as haze generators or hazers, create atmospheric effects (haze) that tend to be less dense than fog machines, allowing them to be used for more subtle looks. Depending on the ventilation of a venue or location, this haze can remain airborne for hours. Due to the small particle size of hazers’ output, under 5 microns, a hazer typically takes longer to fill the same volume of space with a visible effect compared to a smoke machine.[13]

haze machines

Haze machines are often the first choice for larger events, theatre, ballet and concerts and for good reason as even medium sized machines can run for many hours continuously and the underlying process used to create the haze results in much ‘finer’ fog, often with significantly longer hang times and with an improved ability to highlight light rays with a higher degree of light transmission than smoke machines.

Haze machines do not work by heating a liquid, but by atomizing a liquid by compressing the liquid through a fine nozzle/nozzles (similar to how advanced diesel engines can atomize fuel at super high pressures, creating a fine mist of fuel and air that improves ignition and efficiency).

This fine mist is made up of much smaller particle sizes compared to smoke and is produced without the use of heat, arguably producing ‘cleaner’ mists (but may consider this assumption objective as mist compounds are still not quite ‘pure’! ) The liquid is forced through the machine’s nozzle or nozzles using high pressure compressor units and therefore the machines also run cool compared to fog machines. However, it should be noted that the compressors in many haze machines are not entirely silent and care may need to be taken with their location and noise cancellation in quieter performance, theater or ballet applications.

Haze fluids are also available in water and oil based formulas. Similar to smoke/fog machine fluids, water-based fog fluids are made from a water/glycol mixture. However, oil based foggers differ in that they are made from mineral oil and therefore although many modern foggers can run on either type of fluid we would advise that fluid compatibility be carefully considered.

Both types of liquid produce a broadly similar effect, but there are some subtle differences. Oil-based haze tends to last longer and dissipate more slowly, but can also have a higher likelihood of triggering fire alarm sensors, which include specialty hydrocarbon sensors.

Water-based fogs, on the other hand, are lighter, have shorter hang times, and tend to dissipate slightly faster, creating a slightly more “cloud-like” effect, as they are also more affected by air currents within a venue.

Overall, haze is much less likely to set off fire alarm systems than smoke machines, however many factors are at play here and there is no guarantee that haze will not set off building or venue alarm systems.

advantages

Excellent control over output level and distribution in a room, venue or on a stage

Uncomplicated operation and in larger venues, once adjusted to the relevant output levels and schedule, hazers can often be considered a set-and-forget device, as even as levels increase, there is no risk of opacity (thickness/darkening of smoke or fog) that this can become apparent when fog machines are constantly producing output

Produce the ideal effect for highlighting light rays – sufficient haze transmission to not obscure performers, while effectively highlighting lighting elements within a venue or on stage

Different smoke fluids can produce smoke/mist with longer “hang times”, thinner or thicker appearances, and faze machines can typically be used with a variety of smoke fluids (although some manufacturers insist on specific brands or compositions).

Building fire alarm systems are less likely to be triggered than smoke and fog machines (but we don’t offer any guarantees here and your mileage may vary – if in doubt, do extensive testing before each service!)

How to Use a Fog Machine and Frequently Asked Questions

How to use a smoke machine for your spooky Halloween decorations

Spirit Halloween’s Halloween experts are here to teach you how to use a smoke machine indoors or outdoors so you can scare your neighbors and guests by creating the spookiest Halloween scene they’ve ever seen.

For your convenience, we’ve compiled a list of the most frequently asked questions about smoke machines below. Listen!

What is a fog machine?

A fog machine is a machine that creates what looks like “fog” to the human eye. The idea behind a smoke machine is to cover up what’s behind it. The fog is usually thick enough to block those directly in its path from seeing what it covers while creating a spooky scene. Fog machines pump out different amounts of fog depending on the wattage and can be controlled by a timer or remote control if desired to produce continuous fog.

How do fog machines work?

Most fog machines work in conjunction with fog juice or fog fluid, which is a combination of water and glycol. This mixture heats up and creates the white mist you see in the air.

How do I use a fog machine?

Step 1: Make sure you have all the necessary components along with the appropriate smoke machine fluid (juice), cleaner and, if desired, a smoke machine timer and remote control. Follow the instructions on your fog machine carefully.

Step 2: Test drive your smoke machine before displaying it at a party or as part of your decorations. This way you will know the exact visual effect it will create with your home and other props. You should also test it beforehand to make sure it’s running properly and that you’re aware of the setup time. Many machines need a few minutes to warm up before they start producing fog, so allow plenty of time for this. If you need dry ice or other supplies, make sure they’re nearby.

Step 3: See how much fog your machine produces so you can place it where you want it. If you’re not sure where to place your machine, test it out in several areas to see which placement looks the spookiest.

Step 4: Set the timer or remote control if you use them so you know exactly how they work. Then you are ready for Halloween!

How can I control the timing of my fog machine?

As mentioned above, there are two ways you can control your smoke machine: manually or with a timer. If you want to roam freely at your Halloween party without worrying about your smoke machine all night, a timer is definitely the way to go. With a timer, the duration of the fog can be regulated from 0.5 to 10 seconds, the intervals can be between 10 and 200 seconds. You can give your guests a glimpse of what’s behind the fog, and then, once they pique their curiosity, have it pumped back in at its largest capacity.

Some fog machines are remote controlled, allowing you to add more fog or stop the fog from up to 30 feet away.

How long does my fog machine produce fog?

How long your fog juice will last depends on the wattage of your machine. A liter of fog juice will typically burn for six hours in a compact 400-watt fog machine (four hours in a low-lying machine) and a 1,000-watt machine for two hours. Obtain appropriate fog machine fluid to ensure you have fog effects for the duration of your party or entertainment.

Fun Fact: Your fog juice will last up to three years unopened and two months if opened, properly resealed and uncontaminated.

How can I use smoke machines as part of my Halloween decorations?

Smoke machines are a perfect addition to the rest of your haunted Halloween home. Eventually, you create an illusion that jump scare lovers will be drawn to. They’ll want to know exactly what the mist is hiding… as they go very slowly and prepare to take a look and find out.

You can use light to hide the fog and create even scarier effects. A bouncing light, either from a flashlight or other source, gives viewers a now-you-see-it-now-you-don’t feel, which is perfect for making them cringe in shock when they see one move Hand rises from the fog.

Another way to incorporate fog into your spooky decor is to use animatronic Halloween props to combine fog and other spooky elements. A popular animatronic is our Man’s Possessed Friend. Hook it up to your machine (sold separately) and it seems like mist escapes from underneath Bubba the dog as he prepares to sink his razor-sharp teeth into anyone who passes. His bark will have anyone shaking in horror as they see his bestial glow as mist swirls around him!

Check out this YouTube video to see Bubba in action in this spooky dog ​​animation:

Other spooky animatronics that can be greatly enhanced with the use of a smoke machine include the Fogging Skull Pile and Fogging Gaseous Ghoul.

What types of fog machines are there?

Fog machines vary in wattage, which determines how much fog they put out. Which type of fog machine is right for your Halloween decorations depends on the mood you are creating and the space you want the fog to cover.

The higher the wattage of your fog machine, the more fog it will produce. For example, the 400-watt metal fogger produces 2,000 cubic feet of fog per minute, while the 1,000-watt fogger produces 3,000 cubic feet of fog per minute.

Some fog machines are labeled professional and last longer. There are also special low-lying smoke machines that aim to cover the area closest to the ground. These require a special low lying mist juice to get the right effect. What sets these ground foggers apart from other foggers has to do with how the fog is distributed. These machines were specially designed to prevent the mist from rising into the air, creating an eerie sight for anyone who dares step through. They have a compartment for ice or dry ice that helps keep the fog low to the ground so you can create the perfect spooky look. Note that only 400 or 1,000 watt fog machines can be used with Spirit Halloween animatronics.

Safety tips for smoke machines

When using a smoke machine, safety precautions should be taken so that everyone can have a fun and exciting Halloween or Halloween party without getting hurt. The most important thing you want to make sure is that the fog is being used appropriately and that there is enough visibility where people will be walking. Smoke machines can create the perfect spooky atmosphere and still allow your guests to mingle freely, but you don’t want to completely obscure the areas people are traveling through.

Locate your smoke machine away from anything that may be flammable and plug it into a grounded outlet. Also, make sure it’s in a place you can access easily, as you’ll want to check it regularly, even if you’re using a remote or timer. Place your smoke machine far enough away from your smoke alarm to prevent possible triggering.

Make sure you are using the correct smoke juice and cleaner in your smoke machine. Don’t try to make your own as it may affect how your machine works. Also, make sure you’re using the right type of fog juice for the type of machine you’re buying. You don’t want to mix and match juices as each type of mist juice is designed for a specific type of machine. Only use officially approved products with your machine.

What Are Other Uses for Fog Machines?

Of course, it’s all about October 31st and the days leading up to it, but there are many other uses for smoke machines. You can certainly use the machine all year round, be it on other holidays like New Year’s Eve or when you’re DJing at a party to bring some fun effects to the dance floor. You can even use them during a film production or a theatrical performance.

How to maintain your fog machine

We can’t say it enough: make sure you only run your smoke machine on the specific type of smoke juice it needs. Do not attempt to make your own or substitute anything else as this may damage the machine.

When you are finished using your smoke machine, you should unplug it and let it cool down. Then make sure you empty out all the fog fluid before adding the fog machine cleaner. Run your fog machine again until the cleaner is completely gone. This ensures that your fog machine runs smoothly and safely the next time it is used. If the instructions ask you to do a test run regularly, be sure to do so.

Happy haunting!

Extracting oil and cleaning associated equipment requires a unique environmentally friendly cleaning method and must meet the highest environmental, health and safety standards. In particular, sensitive power generation systems and electrical components require regular maintenance and cleaning, since failures cause damage in the millions every year. However, more than two-thirds of these failures are preventable through routine maintenance.

Effective industrial cleaning extends equipment life and reduces or eliminates costly repair programs. Manual cleaning is often postponed to avoid production line downtime. The company ICS Ice Cleaning Systems offers dry ice blasting technology for fast, safe and economical cleaning of equipment on site – without disassembly or the need to cool down the equipment. Dry ice blasting uses solid carbon dioxide (CO2), a non-abrasive medium that will not damage the surface or equipment. Accelerated dry ice pellets are blasted at supersonic speeds and sublimate on impact, resulting in surface cleaning. Using dry ice cleaning technology is safe for most electronic devices.

Generators, turbines, stators, rotors, compressors, boilers and steam generators with heat recovery can be cleaned with dry ice blasting. This process is non-conductive and environmentally friendly compared to traditional cleaning methods. Dry ice blasting reduces the chance of catastrophic failure, improves megohm readings, increases polarization indices, and improves heat dissipation. Dry ice eliminates secondary waste and leaves no film or residue on contact surfaces. This process drastically reduces cleaning time and provides detailed cleaning that allows for faster reassembly with no drying time and significantly reduces costs.

Benefits of dry ice blasting electrical equipment

Dry ice cleaning is a process that can be used without hesitation on almost all electronic devices. It does not cause damage to stator slots, turbine blades or other sensitive components. Popular applications include hydroelectric power generation equipment (stators and rotors), transformers, substations, gas turbine generators, insulators, motor control centers, power distribution panels and system components.

– Safely cleaned equipment,

– Safe for the environment, safe for employees

– cleaning on site,

– Dry – non-conductive method

ELECTRIC MOTORS

Removal of accumulated carbon that can cause engine damage

Removal of dirt from electronics without having to disconnect or disassemble the device – the process is dry and non-conductive.

Dry ice cleaning enables on-site cleaning of electric motors, saving time and money by reducing manpower and downtime.

GENERATORS

Dry ice blasting cleans power generation equipment, reducing downtime due to overheating. The process also allows the units to be cleaned in the field without damaging wiring and insulation.

TURBINES

Dry ice cleaning is ideal for turbines. It is non-abrasive and allows debris and other foreign materials to be removed without disturbing the blade.

ISOLATORS AND SWITCHES

Fine electrical components can be safely cleaned with dry ice. The process does not require any solvents. This process is dry and generates no secondary waste. It removes dirt from electric cables without damaging their insulation.

POWER PLANTS

During peak electricity loads in summer, power plant operators have to operate all generators at maximum efficiency. Dry ice blasting allows power generation systems to operate at optimal efficiency, preventing potentially catastrophic failures. Because dry ice sublimates, there is no secondary waste and therefore no disposal or drying is required.
