I have a nitrous express bottle heater. I was wondering if I needed that solinoid looking deal. [IMG][/IMG]

Thanks. -Corey

 

I believe your referring to the pressure switch. For the heater to be fully automatic (shut off/on based on bottle pressure), yes its nice to have. Any of the site sponsors can set you up with one.

If you do not use one, and just use a switch to heat your bottle, you may risk leaving the heater on too long and overpressuring the bottle, which will likely result in blowing the rupture disk and losing your nitrous ($50+ for a refill and $3.95 for a new rupture disk), or perhaps worse case over pressuring the bottle to where the bottle fails.

Here is the DynoTune one, its $49.

For the price of one bottle fill, well worth the cash IMHO.

Thanks, I think I will call up the guy that I bought it from, he claimed it was his solinoid, not part of the bottle heater.

 

Here is a Pic of a Pressure switch on a Bottle.

 

How come your pressure switch looks different from the picture? and mine too?

 

Opps your right, I got it from 860 Performance when I got a spare NX bottle, I thought it was NX switch, but it obviously isn't (he is an NX dealer)...

 

so the nx valves have alot of provisons then? I looked at my zex bottle and it has a burst disc and the output for the nitrous, nothing on the sides. Could I just T off the line to a pressure switch? I think I might just wire the heater to a seperate switch than the nitrous on, then I could just look down at my pressure gauge I have up front and shut the heater off. Or does it work so well it may heat up too fast going this method?

 

You can use this on your -4 bottle nut.

Of course, the bottle would have to be open for the pressure switch to work. If the bottle was closed the pressure switch would keep trying to heat the bottle and again you would risk blowing the rupture disk.
