Copeland Comfort Control (Alco) 060966 Accumulator

The Copeland Comfort Control (Alco) 060966 is a professional-grade A-AS4105 suction accumulator designed to safeguard refrigeration compressors from liquid slugging and catastrophic flood-back. Built for heavy-duty HVACR system protection, this 4-inch diameter vertical unit features a 10-inch shell height and 5/8" sweat ODF connections, ensuring a precise fit in high-performance suction lines. With a 300 PSI maximum working pressure and a 430°F fusible plug, it maintains structural integrity under rigorous thermal cycles, operating efficiently within an evaporator temperature range of -40°F to +40°F.

For technicians managing refrigerant oil return, the A-AS4105 utilizes an internal U-tube with a screened metering orifice to prevent debris from clogging the oil passage while ensuring steady lubrication back to the crankcase. The corrosion-resistant epoxy powder finish provides a durable barrier against moisture and harsh environments, making it a reliable refrigeration component for HFC, HCFC, and CFC systems. This liquid-vapor separator is essential for heat pump applications or systems subjected to frequent hot gas defrost cycles, effectively trapping liquid charge before it reaches the compressor valves.

• Enhanced Compressor Longevity: Prevents liquid slugging by intercepting excess refrigerant before it can enter the cylinders.
• Efficient Oil Management: High-quality oil return orifice ensures positive oil flow without allowing excessive liquid return.
• Robust Construction: Solid copper connections and an epoxy-coated shell offer superior corrosion resistance for long-term field use.
• Low Pressure Drop: Engineered internal geometry minimizes suction side resistance to maintain overall system COP.

Is the A-AS4105 compatible with R-410A?
This model is rated for a 300 PSI max working pressure, which is typically standard for HFC and HCFC refrigerants like R-22 and R-404A. Always verify your high-side and operating pressures against the 300 PSIG limit before retrofit or installation.

Where should this suction accumulator be installed?
For maximum HVACR system protection, install the unit in the suction line as close to the compressor as possible, ensuring it is positioned vertically to allow for proper U-tube functionality and oil metering.

What is the holding capacity of this unit?
The model A-AS4105 has a nominal holding capacity of approximately 4.0 lbs of liquid R-22 at 40°F, making it suitable for systems requiring medium-volume liquid storage.
