Sporlan 470112 Accumulator

The Sporlan 470112 (Model VPA-5811-6-SRD) is a high-capacity suction line accumulator engineered to prevent liquid slugging and protect compressors in commercial refrigeration and HVAC systems. Featuring 3/4" ODF solder connections, this vertical accumulator utilizes a specialized internal U-tube design to ensure metered liquid refrigerant and oil return, maintaining proper lubrication even under varying load conditions. Specifically designed for compatibility with most CFC, HCFC, and HFC refrigerants, the VPA series is built to withstand rigorous high-pressure environments. The ODF copper connections facilitate easy brazing into the suction line, while the internal screen prevents debris from entering the compressor inlet. Veteran technicians rely on this refrigeration accumulator for systems where liquid floodback is a risk during defrost cycles or low-load operations. This Sporlan accumulator provides the necessary surge volume to manage liquid surges effectively, ensuring long-term system reliability and stable suction line pressure.

• Optimized Oil Return: Features a high-flow U-tube with an orifice calibrated for consistent oil return to the crankcase.
• Heavy-Duty Construction: UL and C-UL listed with a powder-coated finish for superior corrosion resistance in demanding field conditions.
• Compressor Protection: Functions as a permanent reservoir to trap excess liquid refrigerant, preventing mechanical damage from slugging.
• Versatile Application: Suitable for heat pump systems and standard refrigeration racks requiring a 3/4" connection.

Common Questions

What is the purpose of the 3/4" ODF connections on the VPA-5811-6-SRD?
The ODF (Over-Drawn Female) solder connections are sized specifically to match 3/4" copper tubing, allowing for a standard braze joint that maintains flow velocity and minimizes pressure drop in the suction line.

Can this Sporlan accumulator be used with R-410A systems?
Yes, the 470112 is rated for high-pressure refrigerants, including R-410A, making it a reliable choice for both legacy R-22 retrofits and modern high-pressure installations.

How does it handle oil return during low-load periods?
The internal U-tube includes a metered orifice and a screen that uses a pressure differential to pick up oil from the bottom of the vessel, ensuring the compressor never runs dry during extended cycles.
