The helical oil separator features a centrifugal flow path achieving approximately 99% efficiency of oil separation with low pressure drop. Testing by an independent laboratory found that only 0.006% oil by volume was being discharged into the system after leaving a helical oil separator.
Poly Run helical oil separator can help to reduce the vibration and noise that caused by compressor. While the parallel compressor system in unloading energy or charging, it still can keep the high oil separation efficiency, because of special design by poly Run for the helical flighting
Installation
Before install the oil separator, oil pre-charge is required. The charging oil should be kept on above of the oil tank. To pre-charge the oil is very important, this can avoid damaging the needle valve. And the oil we charged must same as the oil in the crankcase. The oil separator should be installed on the outlet line which between the compressor and condenser
Note
A check valve should be located downstream of the outlet connection. This check valve is to prevent liquid refrigerant migrating from the condenser, and with properly pipe disposed. The oil separator must be installed vertically. Proper piping practice should be adopted to prevent excessive loads or vibration at the inlet and outlet connections
