Key Features
- Model: A-WZ 559011
- Connection Type: 1-3/8″ ODF sweat
- Shell Diameter: 4″
- Maximum Working Pressure (MWP): 600 psig
- Construction: Hermetic weld for superior leak integrity
Product Overview
Oil separators are a critical component in refrigeration and air conditioning systems, capturing compressor oil from the discharge gas and returning it to the crankcase. This prevents oil starvation at the compressor, reduces oil circulation in the system, and helps maintain efficient heat transfer across evaporator and condenser coils. The Copeland 066139 is designed to integrate seamlessly into systems where compressor oil management is essential to long-term reliability.
