Nitrogen system

[thedjay]

I just finished installing a nitrogen system in my
restaurant/lounge its not perfect but almost there.
Did anyone install a system like this?


Thanks,
Henry

where's the laser?

How long do you get out of a cannister of Nitrogen? Ive been thinking about doing it, but have always been told they dont last long, like one or two uses out of a cannister!

[teker]

Where is your lounge located?

[thedjay]

My restaurant lounge is in bayridge brooklyn its called dish. There are two different types of systems that i know about. C02 or liquid nitrogen. The C02 is ok but the tanks are 60lbs so it doesnt last that long and its high pressure over 1000psi. My Liquid nitrogen tank is 300lbs and lasts much longer and only 300 psi. If you want to do a system Scott e-mail me c1053@aol.com and we will talk.

that room doesn't look too large. it must be loud as hell. the club i once worked at had a nitrogen system and even with a 3 story ceiling in a room that held 2500 people it was still loud...with the PA on.

[thedjay]

Its loud but no way near as loud as C02. I dont use it to much. I just wanted to figure the system out. I only used it 3 time during the summer. If i had to pay for someone to install it i would have never done it. Even the system in the place is overkill but i enjoy doing the install, building speakers and love the anologe sound. I think its one of the better systems in bayridge. Thats why i ask questions about anologe system because its a hobbie for me and i dont plan on doing it for a living but like to learn more about it.

We have a big nitrogen system here in San Francisco at 1015 Folsom. It is 4 cryo soleoid valves in each corner of the main room approx. 10' off the floor all pointing to the center of the room. Each solenoid attaches directly to a 160 liter dewar tank. The LN2 is internally pressurized to 200-250psi and the relaease is triggered via DMX relays through the lighting console.
Each tank costs around $400 for the rental, liquid and delivery. We usually blast the room for 30-60 seconds and can get a max of 10-12 blasts at the 30 second blast rate. We have also installed a timed ventilation cutout to kill the forced air in the room along with a high pressure water atomizer system that preloads the room with humidity for extra cloud hang time.
It's an awesome effect and last time we used it, the room was packed with people and the clouds were so thick I couldn't see the console and the DJ couldn't see the mixer!! Essentially for $1600 we get a decent weekend of nitrogen blasts. The crowd goes bananas when we hit it every time.
I have seen the CO2 versions and the LN2 is a much better effect.

[RETRODISKO]

great, !! just be careful with the pressure on the output tubes here once the charge was so strong that a tube simply felt down on a girl's head, upsssss

[jnkarrik]

OK, I'll bite. What exactly does a nitrogen system do? Is the intent to supercool the room really quickly, or to produce cloud/fog effects?

[RETRODISKO]

its more the cloudy weffect i think and to impress the people, but i dont think that the room gets colder, the people feels the refresh specially when teyre dancing,


the co2 (the name we use here) its used in spetial parts of the night in big clubs, maybe change of record, or some hard part of the tune of the moment, etc,

[jnkarrik]

Then wouldn't a standard fog machine be MUCH cheaper. A gallon of fog juice is cheap and can last for weeks.

[RETRODISKO]

its cheaper but not so spectacular and noisee, Co2 works great in any club, i like it ,

FFFGFGFGGGGGGGGGGGGGG!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!

[thedjay]

A fog machine is a totally different effect. Used more for the effect of beams of light from the lighting system. Here is a pic of my tank that costs about 140 bucks to fill. Mezz Do they have any device that can raise the presure in the tank? Because im using one tank for 3 nozzels that i made and i think the tank is only rated for 300 psi. What size pipe do you have on your set up from the tank to the valves? The extra water in the air must really boost the effect!!

I was dancing recently in Orlando at Disney World. It was a Thursday night, Unofficial Gay Night. In the walk area dont remember what its called. The adult section. Anyway walked into this Club, the DJ booth was amazing, and the sound was good.

But the best part was the CO2 System. While dancing, me and my friend got carried away, we started yelling and shouting at the DJ and with each yell and shout he played less commercial crap.

Next from the center of the dance floor (Ceiling down) A HUGE cloud of cool smoke encompessed the dance floor. To us dancing it felt good and for about 30 seconds we COULD NOT SEE ANYTHING.

The effect was GREAT. I have seen Fog Machines but this was a totally new experience and far superior to a simple fog machine.

I assume this was a CO2 System. All I can say, is WOW !

[RETRODISKO]

i dont have a pěc now we controll the charges in SUnlite light system,,,

We just use the built in pressure building regulator and set it to 200psi. All liquified gas tanks cannot go above 300psi, there is a safety valve that goes if the pressure gets too high. The lines from the tanks to the valves are 12' long braided steel cryo-rated hoses that I think are either 3/8 or 1/2" ID.
The effect really does cool the whole room by at least 15 degrees in less than 20 seconds.

[thedjay]

I know that liquid tanks can only go up to 300psi but i was wondering if there is a way to boost the presure after the tank? I dont know if anyone has seen the system at ice in vegas? But im sure that its more then 300 psi that moves that ln2. Your tanks are only 12 feet away that makes a big difference with the presure. Were are the tanks on the side of the dance floor? Mine is about 25 feet away and its in the basement. I have a 3/8 hose but its to small i need to go with a 1/2 or 5/8 because im using 3 nozzels with one hose.

wow! now that's a fine effects budget at work.

to answer the other question, the nitrogen effect is commonly used to cool down a room, which is why you will generally only see it used in large clubs, and also because it costs a fortune for a limited time effect.

the last club i was working at had two of those bad boys in the picture a few posts up.

[billy416]

i'll try to get the specs on the system i just spoke of. i know that a custom box was built for the triggering and is independant of all the other systems and is not DMX based.

i can tell you (on a basic level) that it is for a room that fills 2500 people with a 2.5 foot story ceiling and runs from a main level side room via copper piping dispersing out of i believe 2 to 3 jets.

i'll try to get PSI and distance info shortly.

Henry,
there is no residue with the CO2, right? not like fog juice residue...

Was this a "hard" project to build?
would it be pretty easy to run a single nozzle system in a home basement with an adjacent laundry room to house the canister....

[thedjay]

No there is no residue left. The system works better when there is humidity in the air. Some clubs have seperate systems that spray a fine mist of water in the air before they use the Co2 / Nitrogen system. A single co2 valve setup with 1-valve and 25ft of High pressure line will run about 1500 bucks Then you need a C02 tank. I use the 50 lb tank, Its about 4 1/2 feet tall. Its not a job for a beginner! You are dealing with very high presure with the co2 or very cold liquid nitrogin -300 degrees!!! You can get burned seriously! Or with the co2 the presure is over 2000 psi ! You also have to wire the valve to a 110v switched source. So you need some electrical skills also. Im not sure how crazy you want to get but if you any questions i will try to help you.

thanks for the info Henry...
humidity huh.... that throws a wrinkle....


I will probably wait till i can learn some more stuff & do some additional research....

Twilo and arc had liquid nitrogen systems and they were fun. 4 blast points and the sound was louder than the PA. I dont think there was any connection to the ventilation system. Ive heard the concept started out in Ibiza.

This is definitely something that only clubs with hte potential for decent moeny can realize. In berlin there is no club that could justify such a system considering its impact on costs. DJ fees and entrance/drink prices are a lot lower. Either that, or skimp out on more important things, like dj fees and sound system.

For the loft party people, I found something that works equally as cool. We threw a few parties a couple years ago that were dangerously hot on the dancefloor. Water was just dripping from the ceiling. This was still in the middle of winter and we would piss off neighbors if we kept the windows opened. Turning down the music and opening all of the big windows at once brought a rush of cold fog into the room. Just like the NO2, you couldnt see shit and the cool air made everything more comfortable. However, the effect was totally silent. People wouldnt even talk. After a minute or 2, close hte windows and bring the music back up. The better djs figured out how to time their tracks with the opening and closings. Those for the worse would simply stop the record. Ricardo Villalobos was the best at absolutely devasting the floor when the music came back up, as if the window action was just a build for a peak in the music.

Great info thread! I thought cryogenifex (spelling) was the only game in town (or around). I know they charge mad loot to install from what I was told.

If you have a bad customer eating at the restaurant u should give em a blast! ;)

[DSA.audio]

yeah.... and a coupla of grand for a small venue (or home) really isn't too bad...


beats the heck out of cleaning fog juice residue......


do you have oxygen sensors to ensure there is enough in the room?

[thedjay]

I dont think there are to many companys that install systems like this. I know Kryogenifex is one of the most popular company's and they really do some crazy stuff!! They use liquid nitrogen setups. If you ever look at the tanks they install and all the pluming thats on them it looks like a weird sience project! They are expensive but it must cost alot for them to be insured! These systems can be very dangerous!!! You are talking about Liquid nitrogen. If the system is not built right you can hurt yourself or people in the club. I dont think they use oxygen sensors. Usuall they HVAC Systems keep the air circulating. My system is way to small for anything like that. But i was in Club ice in vegas and that system is serious!! When they activate it in 15 seconds the hole room is filled! I couldnt see infront of my face! When the Cloud of smoke cleared everyone was still standing so im sure there is enough oxygen in the room.lol I could never use my system when people are eating, They would have a heart atack!lol Its So F.in Loud!! Ill try to put some video up on my myspace page. www.myspace.com/towjr
