Carrier 38AK500410 Accumulator

The Carrier 38AK500410 is a heavy-duty suction line accumulator engineered for large-tonnage commercial HVAC and refrigeration systems. Featuring 2 1/8" ODF sweat connections, this component is designed to manage high mass flow rates while protecting compressors from liquid slugging during flooded starts or defrost cycles. With a 390 PSIG maximum working pressure, it provides reliable performance across high, medium, and low-temperature applications. This HVAC suction accumulator is compatible with a wide array of refrigerants, including R22, R134a, R404A, R407C, R502, and R507. The internal U-tube design and precise orifice metering ensure consistent oil return to the crankcase, preventing mechanical failure in Carrier commercial condensing units. For technicians performing refrigeration system maintenance or 2 1/8" line set repairs, this OEM-spec component ensures the internal volume and pressure drop parameters meet the original equipment manufacturer's strict requirements for system longevity and efficiency.

• Multi-Refrigerant Compatibility: Rated for high-pressure synthetic and HCFC refrigerants.
• High-Flow Capacity: 2 1/8" ODF connections accommodate high-tonnage suction lines without excessive pressure drop.
• Compressor Protection: Prevents liquid refrigerant from entering the compressor suction inlet.
• Optimized Oil Return: Features an integrated metering orifice to maintain proper lubrication levels.
• Durable Construction: Built to withstand the thermal stresses of frequent cycling and high-vibration commercial environments.

Common Technical Questions

What is the maximum operating pressure for the 38AK500410?
This unit is rated for a Maximum Working Pressure (MWP) of 390 PSIG, making it suitable for standard commercial refrigeration and AC pressures.

Can this accumulator be installed in any orientation?
No, for proper liquid separation and oil return via the internal U-tube, this accumulator must be installed in a vertical orientation.

Is the Carrier 38AK500410 compatible with POE and MO oils?
Yes, the materials and internal design are compatible with Mineral, Alkylbenzene, and Polyolester lubricants typically found in R22 and R404A systems.
