I have a zex bottle warmer, but it keeps pressure around 800, which is too low for me because when I spray a big shot, the pressure drops too 700 in a hurry and i get flow problems. I dont want the kind that actually measures the pressure either, cause that means you have to leave the bottle open. Is NOS brand good and what pressure do they stay at?

 

Hmm...dunno. My ZEX heater keeps my bottle pressure at exactly 950 and turns on when it reaches 900.

But I guess you could always bypass the bulit-in thermostats (AFAIK there are two in the ZEX unit) and turning it on and off manually.
Please don't ask me how to bypass the thermostat... Maybe someone could chime in here!

Later,

 

i have a NOS brand heaterand threw away the thermostat. i just watch the pressure on the guage and turn the heater on/off as needed.

Im sure with the zecx,it's just a matter of bypassing the thermostats to do the same trick.
