Sporlan 470093 Accumulator

The Sporlan 470093 VA356S Suction Line Accumulator is a critical preventative component for professional HVACR systems, engineered to stop liquid slugging and protect compressor valves from catastrophic failure. Built with a rugged steel shell construction, this 3/4" ODF sweat connection accumulator acts as a temporary reservoir, capturing excess liquid refrigerant and oil before they can reach the compressor crankcase. The internal U-tube design is optimized for maximum refrigerant flow and features a precision metering orifice that ensures a consistent, safe return of oil to maintain proper lubrication levels throughout the refrigeration cycle.

Designed for field-proven durability, the VA-35-6S accumulator includes an integrated inlet flow deflector that guides incoming refrigerant against the side wall for a smooth, tangential flow. This prevents high-velocity liquid from bypassing the vessel and entering the suction line. With a holding capacity of approximately 3.69 lbs and a compact 3-inch diameter, it is an ideal fit for heat pump systems and commercial refrigeration units where system charges vary. The solid copper connections facilitate reliable brazing in the field, making this a standard HVAC replacement part for technicians prioritizing system longevity and efficiency.

• Liquid Slugging Protection: Effectively separates liquid refrigerant from vapor to prevent compressor damage during startup or defrost cycles.
• Optimized Oil Return: Features a metering orifice protected by a 50x60 mesh screen to ensure safe oil return without excessive refrigerant dilution.
• Superior Flow Dynamics: Tangential flow pattern and U-tube entrance positioning minimize pressure drop across the suction line.
• Corrosion Resistance: Finished with a powder paint coating capable of withstanding 500 hours of salt spray testing for harsh environments.
• Universal Compatibility: Suitable for a wide range of refrigerants and applications, including standard residential and commercial air conditioning setups.

• Where should this accumulator be installed? It must be installed vertically in the suction line, between the evaporator and the compressor, as close to the compressor as possible.
• How do I size this for a system? The VA-35-6S should typically be sized to hold at least 50% of the total system charge for TXV systems or 70% for capillary tube systems.
• Does this model include a fusible plug? Yes, standard Sporlan VA series accumulators are equipped with a fusible alloy plug to comply with UL safety standards for overpressure protection.
