Are nitrous tanks compatible with CO2? I know in the paintball community there are different tanks for nitrogen use. I really don't know the technical differences.

I have a used NOS-branded kit last year, I believe this is it:

Never installed it myself, and with the addition of a turbo I'd like to convert it for use as an intercooler chiller. I was hoping to avoid needing the CryO2 install kit since the nitrous kit already has the mounting, plumbing, solenoid, and arming switch. I would need a WOT switch but that is easy to find. I'm hoping I'd just need a purge kit (for shows, I realize this won't effect performance) and the chiller bar itself.

Has anyone tried this conversion or have any suggestions?

 

you can use nitrous as a chiller as well, i'd check on the pricing available in our area between the two gases before worrying about switching.

 

you cant legally fill the nitrous bottle with CO2. No one will fill it with anything but nitrous as the bottle isnt marked for anything else.

 

i believe the regulators are diff.

not to mention, CO2 tanks can be syphon or anti-syphon.

you shouldnt fill a N2 tank with CO2.

CO2 is much more unstable than N2, i dont know if a reg. on an N2 tank would be able to hold it.

 

DO NOT fill a N20 tank or a N/(Air) tank with CO2, the valve seals in the regulator will get destroyed by the CO2 and the temperature change brought about by the phase change when CO2 is depressurized will crack the seals and may cause surface pitting on the valve itself depending on what metal the seat is made out of. Just buy a CO2 tank.

 

Thanks, this is why I was asking. Wasn't sure what the temperature gradient was when depressurized or if the holding pressure was different. Not sure how CO2 would be less stable than N2O, CO2 is inert whereas N2O is an oxidizer when heated, unless you're talking boil point and over-pressurization potential on a 1% hot day.

Did some digging on the CryO2 site and found this:

Sounds like the simplest solution is that if my bottle does have a siphon tube, just use nitrous with the spray bar, then I won't have any filling or compatibility issues, not to mention it will be easier to find a fill station.
