Description

ABSTRACT:
Portable apparatus for servicing a refrigeration system having a refrigerant containing an oil lubricant. The apparatus includes a support frame, a modular housing supported by the frame and defining internal accumulator, condenser, storage, and high and low pressure filter chambers, and a control plate assembly having a plurality of flow passages enabling flow communication between the various chambers. The control plate is adopted for connection to the refrigeration system being serviced, and has control valves operative to control flow of refrigerant through the passages to and between the internal chambers. A processor controls the control valves in a manner enabling selective recovery, evacuation, charging and/or flushing of she refrigerant of the refrigeration system.
