Carrier KH74HV160 Accumulator

The Carrier KH74HV160 Accumulator is a critical suction line component designed to protect compressors from liquid slugging in residential and commercial HVAC units. Featuring a 7/8" ODF connection, this suction line accumulator acts as a temporary reservoir, trapping excess liquid refrigerant and oil before they can reach the compressor’s internal valves. As a veteran-grade OEM Carrier replacement part, it is engineered for high-pressure environments, maintaining an operating threshold up to 450 PSI. Its internal U-tube design ensures a consistent oil return to the crankcase via a precision-sized orifice, preventing oil starvation during low-load conditions. This HVAC accumulator is compatible with a wide range of refrigerants, including R-410A, R-22, and R-407C, making it a versatile choice for heat pumps and packaged RTUs where system charge fluctuations are common during defrost cycles or low ambient operation.

• Total Compressor Protection: Prevents catastrophic liquid slugging by ensuring only superheated vapor enters the suction inlet.
• Efficient Oil Management: Utilizes a metered 7/8" ODF U-tube assembly to facilitate reliable oil return, extending the service life of the compressor.
• Broad Compatibility: Factory-authorized for Carrier and Payne packaged units, heat pumps, and standard split systems.
• Robust Construction: Built with high-strength steel to withstand the mechanical stresses of high-pressure refrigerant accumulator applications.

Is this part compatible with R-410A systems?
Yes, the KH74HV160 is rated for modern high-pressure refrigerants including R-410A and R-134a, as well as legacy R-22 systems.

Can this accumulator be mounted horizontally?
No, this suction line accumulator must be mounted vertically to allow the internal U-tube and oil return orifice to function properly by gravity separation.

What is the primary cause of accumulator failure?
While the Carrier KH74HV160 is highly durable, failure typically occurs due to external corrosion or internal clogging of the oil return orifice from system debris; always install a suction line filter-drier when replacing this component.
