Rheem-Ruud VA-35-6S Accumulator

The Rheem-Ruud VA-35-6S Suction Line Accumulator is a critical preventative component designed to protect compressors from liquid slugging during HVAC system operation. Featuring a 3/4" ODF connection, this vertical suction accumulator ensures regulated refrigerant flow back to the compressor, specifically during low-load conditions or defrost cycles in heat pump applications. Engineered for high-pressure R-410A systems, the heavy-duty steel construction provides a high burst pressure rating, ensuring reliable performance in demanding commercial and residential environments. The internal metering orifice and copper tube design allow for balanced oil return while preventing liquid refrigerant from entering the compressor crankcase. For technicians performing compressor replacements or system retrofits, verifying the Brazed connection sizing and internal volume is essential for maintaining proper HVAC refrigerant cycle integrity. This Protech-certified component is the standard for maintaining Rheem HVAC part compatibility and long-term mechanical reliability.

Key Technical Benefits

• Maximum Liquid Protection: Effectively traps excess liquid refrigerant to prevent compressor slugging and mechanical failure.
• Optimized Oil Return: Features a calibrated J-Tube with a metering orifice to ensure consistent compressor lubrication.
• High Pressure Rating: Specifically designed to handle the rigorous pressure demands of modern R-410A refrigerant.
• Corrosion Resistance: Durable powder-coated finish prevents rust and degradation in high-moisture outdoor environments.
• Direct OEM Fit: Ensures exact installation alignment for Rheem and Ruud condensing units and heat pumps.

Common Questions

What is the primary function of the VA-35-6S in a heat pump?
During the defrost cycle, the VA-35-6S acts as a temporary reservoir for liquid refrigerant, preventing a sudden surge from damaging the compressor valves.

Is this accumulator compatible with older R-22 systems?
While designed for high-pressure 410A, it is functionally compatible with R-22 systems provided the 3/4" suction line sizing and total system charge limits are observed.

Can this unit be mounted horizontally?
No, the 3/4" Suction Line Accumulator must be mounted vertically to ensure the internal baffle and oil return mechanism function correctly.
