The product is basically a heating blanket that is adapted in size to fit around a canister of refrigerant used to recharge heat pumps, air conditioners and refrigerators in a commercial or home setting. The blanket has a heating element within it which heats the canister when placed around the canister. From one corner of the blanket is an electrical cord which runs to a small control unit and then to a plug that fits a common 110 voltage household outlet. The control unit consists of a fitting that is designed to be attached to the valve on the top of the refrigerant canister. This fitting is attached to a pressure sensitive valve that sense the pressure of the refrigerant that passes through the valve. This pressure sensitive valve turns off the flow of electric to the blanket when the gas hits a certain pressure.
