The CAPTURE pump has been specifically designed for refrigerant recovery and recycling systems requiring chiller evacuation to 29.9 inHg while subsequent boosting of refrigerant vapors to a holding tank to 30 psig. CAPTURE pumps are the heart of transportable recovery systems used for recovering low and medium pressure refrigerants, such as R-123 and R-11. Recovery with the CAPTURE pump can be configured ina recovery system to employ the liquid-vapor method. The first step is the recovery cylinder is evacuated with the CAPTURE pump and that pulls the refrigerant from the chiller into the cylinder. Once the liquid refrigerant is recovered, valves are switched on the recovery system, so that remaining vapor in the chiller is evacuated by the pump and boosted into the chiller. The CAPTURE pump then reaches vacuum pressure levels in the chiller that are required by the Clean Air Act.
Pump oil separation from refrigerant vapor and return to pump is accomplished by attaching a standard float actuated oil return found in refrigerators. The oil separator is a proven technology that minimizes pump oil loss even for very large refrigerant systems. DuoSeal pump oil, cat no 1407K-11, is recommended lubricant to operate the CAPTURE pump.
