Sporlan 470110 Accumulator

The Sporlan 470110 Accumulator, also cataloged as VPA589-6SRD, is a heavy-duty suction line accumulator designed to prevent liquid refrigerant floodback from damaging the compressor. Featuring 3/4" ODF solid copper connections, this unit utilizes a vertical U-tube design that ensures maximum refrigerant flow with minimal pressure drop. The internal metering orifice is precision-engineered to facilitate consistent oil return, while a built-in inlet flow deflector directs liquid toward the shell wall for gradual expansion and safe evaporation. Built for longevity in demanding environments, the steel shell is finished with a powder paint coating that exceeds 500-hour salt spray tests. This HVAC compressor protection component is compatible with standard refrigerants like R-410A and R-22, making it a reliable choice for field replacements in both residential heat pumps and commercial refrigeration equipment.

• Enhanced Compressor Life: Effectively captures liquid slugs before they reach the compressor crankcase.
• Optimized Oil Return: Includes a protective screen and calibrated orifice to maintain lubrication without siphoning excess liquid.
• Corrosion Resistance: High-grade powder coating provides superior protection against rust in outdoor condenser environments.
• Low Pressure Drop: Large internal volume and high-flow U-tube geometry maintain system efficiency.
• Direct OEM Replacement: Fully interchangeable with Parker Sporlan VPA589-6SRD for seamless installation into existing 3/4" suction lines.

What causes a suction line accumulator to fail?
Outside of physical corrosion leading to leaks, the most common failure point is a clogged internal orifice or screen. This restricted oil return often leads to nuisance oil safety trips or premature compressor wear. If the system has experienced a severe burnout, technicians should replace the accumulator to ensure no contaminated oil or acid remains trapped in the U-tube.

How do I size this accumulator for my system?
The Sporlan 470110 should be sized based on the system's total refrigerant charge. As a general rule for field service, the accumulator should hold at least 50% of the total system charge to provide adequate protection during defrost cycles or low-ambient cooling operations.

Can this be mounted horizontally?
No, this model is a vertical accumulator. Proper orientation is critical to allow the internal U-tube and inlet deflector to separate liquid from vapor effectively. Mounting it horizontally will bypass the internal safety features and could allow liquid to enter the compressor.
