Nitrous Works MaxPak Bottle Warmer kit
 

MaxPak bottle heater kit includes the new bottle heater plus thermostatic control for safety, plus maintains the optimal 85° F temperature to keep bottle pressure between 1000 and 1100 psi. Includes pressure sensor with automatic shutoff, arming switch, safety valve vent tube, and relay. And the bottle warmer element and instructions.

It is used, retails for $220, I'm selling it for $135, buyer pays shipping. It is the entire kit (and then some, I have included more butt connectors and extra lengths of wire for a custom install) and is all in perfect condition.
