Do CO2 Cryo Jets Set Off Smoke Alarms

Over the past several months we have been asked if CO2 cryo jets or the handheld CO2 cryo guns will set off smoke alarms in nightclubs and event venues; and here is a great video demonstrating how they will not set of the alarms in a normal setting.  When properly installed more than a few feet away from a direct blast into a smoke alarm, the rapidly evaporating CO2 will not set off smoke alarms.  This super cold visual effect is used by hundreds of nightclubs and production companies around the world and we have yet to hear of one setting off a smoke alarm when used as instructed.  Our friends over at POSH Ent were kind enough to share this video of one of Atlanta Special FX handheld cryo guns being blasted directly at a smoke alarm by Felix Lopez, a fireman with the Bayonne Fire Department.  As you can see when placed more than a few feet from the smoke alarm, the 15 foot blast of dense CO2 fog does not set the alarm off.  However when he walks within 3 feet of the alarm it does go off.  Thanks for the great video and please feel free to contact www.AtlantaSpecialFX.com with any CO2 cryo jet questions.  Enjoy.

Does A Dual Nozzle CO2 Cryo Jet Have Less Pressure Than A Single

When searching to buy a CO2 cryo jet system for your company you may have ran across several systems and have a couple questions.  One popular question is "Does the dual nozzle co2 cryo jet have less output than the single nozzle?"  There are a couple of different answers and it really depends on the CO2 tanks you decide to use for your install.  Options for your CO2 tank rentals or purchases are liquid siphon tube tanks in these sizes listed below:

1. 20 lb Liquid Siphon CO2 Tank
2. 50 lb Liquid Siphon CO2 Tank (Seen to the right)
3. 75 lb Liquid Siphon CO2 Tank
4. 100 lb Liquid Siphon CO2 Tank

5. 400 lb Liquid Dewar Tank (Seen Below to the left)

The main differences between the tanks is the pressure that the CO2 is compressed under.  The 20 and 50 lb Siphon tanks are pressurized at approximately 850 psi compared to the Dewar tank at approximately 350 psi.  The Atlanta Special FX Dual Nozzle Cryo Jet does produce a slightly shorter blast of CO2 fog when using the lower pressure refiigerated Dewar tank setup.  Using a high pressure system you should still see approximately 20 feet of cryo fog and more (in humid climates) but should hardly notice a difference.  Click here to watch videos of the units working on a high pressure system.  http://www.atlantaspecialfx.com/Fog-Smoke%20Machines.htm

Are you a mobile DJ or a nightclub looking to add some WOW factor to your show?  Then you might have asked yourself "What is a handheld cryo gun my buddies are talking about?"  The photo to the left shows one version of the popular CO2 blaster known as the handheld cryo gun manufactured by Atlanta Special FX.  Cryo gun foggers have hit the scene hard and add stunning visual effects to otherwise standard DJ sets or club playlists.  This portable cryo blaster has been used by some of the BIGGEST names in the business.  You might have seen the Atlanta Special FX cryo gun at a Steve Aoki, LMFAO, Kesha, or other concert and wondered "What was that" This "cool" fog effect is also used weekly during NCAA college football, NBA, NFL and NHL as well as countless high schools and colleges across the nation.  Another great place to see this effect in action is at your local super club or bar.  The super cold CO2 fog is especially helpful in cooling down venues once a lot of guest fill the room.  Most nightclubs and bars just simply don't have the HVAC cooling systems strong enough to keep up with the rising heat generated by hundreds of dancing guests.  All it takes is a few second blast to cool the dance floor approximately 10-20 degrees.  For more information on the Handheld Cryo Gun click here http://www.atlantaspecialfx.com/Fog-Smoke%20Machines.htm or visit the FAQ page at http://www.atlantaspecialfx.com/Cryo_Jet_CO2_FAQs.pdf

How To Install A CO2 Cryo Jet by Atlanta Special FX

If you have never installed a CO2 cryo jet system it may seem like a daunting task.  After you read through this short paragraph you will know all the ins and outs of installing your own CO2 cryo system with either high pressure tanks or low pressure Dewar tanks.  All the pros in the special effects world understand it doesn't take years of experience to install the CO2 cryo jets manufactured by Atlanta Special FX.  These cryo blasters are engineered to save you time and money.  They can be mounted in a variety of positions allowing for easy setup in all types of venues. 

If you notice on the photo to the left the lower, and back, mounting plates are designed to use screws for mounting to the floor, wall, and ceiling.  The multi mounting points allow the CO2 units to be installed right side up, lefts side, right side and upside down.  It also includes a pre drilled hole for easy mounting to a truss system using a J-clamp or C-clamp.  Once you have decided on your mounting the next thing to do is consider the location of your tanks in relation to your cryo nozzles.  Ideally you will want to keep your tanks as close to the CO2 jets as possible and always use tested and approved cryo hosing.  With that in mind, here are some general guidelines (NOT REQUIREMENTS) you will want to follow with your hose lengths:

1. Do your best to stay at 50-70 feet or less from your tanks when using low pressure Dewar tanks. (Closer is better)
2. Try to keep a direct line between your cryo jets and your tanks.  (The less 90 degree turns the better)
3. When using high pressure tanks you can use longer hoses (But if the CO2 sets in the hoses for extended periods of time between shots you will experience the noise before the white fog comes out)
4. It is optional to use T fittings and attach multiple jets to a single hose.

Now that you have decided the location of tanks and the location of cryo jets, you will need to distinguish between the cryo hose ends to determine which hooks to which.  The brass end is a standard CO2 fitting and attaches to the liquid CO2 bottle and the silver end attaches to the cryo jet.  Once you have attached your hoses you will now need to determine how you will power the jets on and off.  Most industry professionals use a 4 channel DMX dimmer / switch kit. (Sold Separately).  Others use items such as foot switches, push button firing systems, and even as manual as a surge protector.  The cryo jets only need a simple on off signal.  When the jet is on, CO2 plumes of fog will shoot from the nozzle and when they are off there will be no noise or fog.  The last things you will want to do are test fire the jets, without the gas on, listening for the clicking on/off sound.  Once you have tested the on/off it is time open your CO2 bottle.  Be sure the cryo unit is off, open the valve on top of the CO2 bottle all the way and the line will pressurize.  It is always good practice to leave the bottle closed until just before you need the effect.  This will ensure a nice, instant plume of fog when you power the CO2 fogger on.

CO2 fog is a great way to entertain your guests as well as provide stunning visual and audible effects while cooling the room down.  This is why CO2 foggers are a popular item for any nightclub venue.

We hope this article has shed a little light on your CO2 jet purchase.   If you have questions or comments, a professional technician is always standing by to assist you.
