Copeland Comfort Control (Alco) 066138 Oil Separator
The Copeland Comfort Control (Alco) 066138 Oil Separator is a critical HVACR refrigeration component designed for high-efficiency oil management in commercial systems. Also identified by model A-WZ 55889, this unit features a robust 4-inch shell and reliable hermetic weld construction, engineered to withstand a maximum working pressure of 600 PSIG. By effectively capturing entrained oil from discharge gas and returning it to the compressor crankcase, the 066138 oil separator maintains optimal thermal transfer across evaporator coils and prevents lubrication failure. The 1 1/8" ODF sweat connections allow for a secure, leak-proof integration into various refrigerant lines. This centrifugal oil separator is built for technicians who demand precise compressor protection and long-term HVAC system efficiency in demanding high-pressure applications. Its cross-compatibility with Emerson Flow Controls ensures it meets the exact specifications required for maintaining refrigeration oil levels in complex circuits.
Key Benefits for Technicians:
- Optimized Heat Transfer: Prevents oil coating in the evaporator and condenser, significantly improving the heat exchange rate of the refrigerant.
- Extended Compressor Life: Ensures consistent return of lubricant to the sump, preventing mechanical seizures due to oil logging.
- Rugged Build Quality: The hermetic weld construction eliminates potential leak paths common in bolted or gasketed alternatives.
- High Pressure Rating: Rated for 600 PSIG, making it suitable for modern high-pressure refrigerants and demanding duty cycles.
- Universal ODF Sizing: Features 1 1/8" ODF weld connections for standard piping interfaces in commercial refrigeration.
Common Questions:
Is the Copeland 066138 compatible with current high-pressure refrigerants?
Yes, the 600 PSIG maximum working pressure makes this unit compatible with most standard HCFC and HFC refrigerants used in commercial HVACR applications.
How does this model compare to the A-WZ 55889?
The 066138 and the A-WZ 55889 are technically identical components. They share the same 4" shell diameter, hermetic design, and 1 1/8" connection points.
Does this unit include the internal float mechanism for oil return?
Yes, this centrifugal oil separator utilizes an internal float valve assembly to automatically return separated oil back to the compressor when the reservoir level reaches the trigger point.
