Oil Reclaim System
The oil reclaim system operates to return oil back to the oil reservoir by recovering it from 2 areas on the machine. The primary area of recovery is from the guide vane housing. Oil also is recovered, along with refrigerant, from the cooler.
Any refrigerant that enters the oil reservoir/transmission area is flashed into gas. The demister line at the top of the casing will vent this refrigerant into the suction of the compressor. Oil entrained in the refrigerant is eliminated by the demister filter.
During Normal Machine Operation, oil is entrained with the refrigerant. As the compressor pulls the refrigerant into the guide vane housing to be compressed, the oil will normally drop out at this point and fall to the bottom of the housing where it accumulates. Using
