Oil Separators, type OUB
Introduction
The oil separator type OUB is for use in all
refrigeration plants where the compressor
lubricating oil must be returned direct to
the compressor oil sump under all operating
conditions.
In this way lubricating oil from the compressor
is prevented from circulating with the refrigerant
in the refrigeration system itself.
Features
Ensures oil return to compressor oil sump.
n Prevents compressor breakdown caused by
lack of lubrication.
n Increases compressor operating life.
High efficiency caused by interaction of reduced
flow velocity change of flow direction for oil
concentration, oil separation collection of
separated oil at high temperature, and automatic
oil return to crankcase.
Protects against liquid hammer in compressor.
Better utilization of condenser and evaporator
capacity (no oil-gas collection).
Pulsation and noise damping on high-pressure
side of system.
