Copeland Emerson ALCO Oil Separator
Professional refrigeration oil separators designed to remove oil from compressor discharge gas and return it to the oil system, helping maintain proper compressor lubrication and reduce oil circulation throughout the refrigeration circuit.
A-F Series A-W Series A-WZ Series A-FC Centrifugal Series Commercial RefrigerationReliable Compressor Oil Management
The Copeland Emerson ALCO Oil Separator range is designed to separate compressor oil from hot refrigerant discharge gas and return the collected oil to the compressor crankcase or oil reservoir.
Proper oil separation helps maintain reliable compressor lubrication, reduces excessive oil circulation through evaporators and improves overall refrigeration system operation.
Copeland Oil Separator Series
Traditional flanged construction designed for refrigeration applications where serviceability and proven mechanical oil separation are required.
Flanged ServiceableHermetic welded construction for standard commercial refrigeration and compressor discharge applications.
Welded Standard PressureHigh-pressure welded construction designed for systems requiring higher working-pressure capability.
High Pressure WeldedUses centrifugal separation technology to provide high-efficiency oil removal in demanding refrigeration systems.

Which Oil Separator Series Should I Choose?
Why Is an Oil Separator Important?
How Does an Oil Separator Work?
Hot refrigerant discharge gas leaving the compressor contains a certain amount of entrained compressor oil.
Inside the oil separator, the gas velocity and flow direction are changed so that oil droplets can be separated from the refrigerant gas. The separated oil collects in the lower portion of the separator.
An internal oil-return mechanism then allows the collected oil to return to the compressor or external oil-management system.
