Emerson Alco 060827 Accumulator

The Emerson Alco 060827 (Model A-AS61411) is a high-performance vertical suction line accumulator engineered to protect commercial compressors from catastrophic liquid slugging. Constructed with a 6-inch diameter and a 14-inch shell height, this unit acts as a critical temporary reservoir for liquid refrigerant and oil, preventing floodback during high-load periods or defrost cycles. It features 1 3/8" ODF sweat connections made of solid copper to ensure rapid, leak-free brazing in the field. With a 300 PSI maximum working pressure and a nominal capacity for systems up to approximately 18.8 tons (R-22), it is fully compatible with CFC, HCFC, and HFC refrigerants, including R-410A, R-134a, and R-404A. The internal U-tube design, complemented by a screened orifice and inlet deflector, ensures metered oil return to the crankcase while maintaining system efficiency across an evaporator temperature range of -40°F to +40°F. The durable epoxy powder paint finish provides superior corrosion resistance for demanding mechanical environments.

• Superior Compressor Protection: Prevents liquid refrigerant from entering the compressor, eliminating the risk of broken valve reeds or crankshaft failure.
• Efficient Oil Management: Utilizes an internal suction accumulator U-tube with a screened orifice to ensure consistent oil return at a controlled rate.
• High-Durability Construction: Features a corrosion-resistant epoxy coating and solid copper 1 3/8" ODF connections for long-term reliability in the field.
• Versatile Compatibility: Rated for a wide variety of HVAC refrigerants and high-pressure systems up to 300 psig.

What is the primary function of the A-AS61411 in a commercial system?
The unit serves as a buffer to trap liquid refrigerant before it reaches the compressor, allowing only vapor to exit while metering oil back to the crankcase through a calibrated orifice.

Can this accumulator be used with R-410A systems?
Yes, it is designed for use with high-pressure HFCs, though it is critical to never exceed the 300 PSI nameplate maximum working pressure during operation.

Is the internal orifice protected against debris?
Yes, the metering orifice is equipped with a fine-mesh screen to prevent contaminants from clogging the oil return path, ensuring consistent lubrication for the compressor.
