Abstract
A refrigerant recovery unit for accurately filling a refrigerant system with a refrigerant is provided which includes a storage vessel for holding refrigerant, sensors to assist in determining the pressure of the refrigerant in the storage vessel, a controller to control the flow of refrigerant from the storage vessel to the refrigerant system to be serviced, and a heating device to heat the refrigerant, which is activated only if heating is required, as determined by data received by the controller.
