Sporlan 470115 Accumulator

The Sporlan 470115, recognized by model number VPA-5815-7-SRD, is a high-capacity suction line accumulator engineered to prevent liquid slugging and protect the compressor in residential and commercial refrigeration systems. This unit features a 7/8" ODF solder connection, making it compatible with standard copper piping used in high-pressure R-410A systems as well as R-22 and R-134a applications. Its vertical orientation utilizes a precise internal J-tube with a metered orifice and screen-protected oil return to ensure consistent lubricant flow back to the compressor crankcase. Built for durability, the VPA series accumulator provides essential protection during defrost cycles or low-load conditions when refrigerant flooding is most likely. Integrating this HVAC suction accumulator into your liquid management strategy ensures reliable refrigerant floodback protection and extends the lifecycle of critical system components.

• Liquid Slugging Prevention: Acts as a dedicated reservoir to trap liquid refrigerant and prevent hydraulic shock to compressor valves.
• Optimized Oil Management: Features a calibrated metering orifice to return oil at a controlled rate, preventing oil logging in the evaporator.
• High Pressure Rating: Designed to withstand the rigorous operating pressures associated with modern high-efficiency heat pumps.
• Corrosion Resistance: Finished with a powder-coated exterior to withstand harsh environmental conditions in outdoor condensing units.

What is the maximum operating pressure for the Sporlan VPA5815-7SRD?
This model is rated for a Maximum Rated Pressure (MRP) of 450 psi, making it suitable for most R-410A and R-22 field installations.

Can this accumulator be installed in any orientation?
No, for effective liquid trapping and oil return, this vertical-style accumulator must be mounted upright as specified by the manufacturer's flow direction indicators.

How do I ensure proper oil return through the J-tube?
Proper sizing is critical; the suction line velocity must be maintained to ensure the internal pressure differential allows the metered orifice to pick up oil from the bottom of the vessel.
