Refcomp SRC-S(W)-133 SRC-S-133-L4 Semi-Hermetic HVAC Screw Compressor

The SRC-S(W)-133 hvac screw compressor provides versatile capacity adjustment options to handle dynamic cooling loads. It supports both 4-step capacity regulation (100%, 75%, 50%, 25%) and continuous stepless control from 100% down to 25%. This design allows precise output matching to actual system demands, improving partial-load efficiency and reducing operational energy consumption in commercial and industrial systems.

Built for high-efficiency refrigeration and water-chilling setups, this hvac screw compressor incorporates standard auxiliary connection interfaces for system optimization:

22 mm Economizer Port: Facilitates subcooling circuit integration to expand cooling capacity and boost overall COP during peak load operations.

10 mm Liquid Injection Port: Enables direct liquid injection to control discharge temperatures during demanding operating conditions.

Standardized Piping Connections: Features a 54.1 mm (2-1/8") suction connection and a 42.2 mm (1-5/8") discharge connection for straightforward piping integration.

Equipped with an integrated INT69 SNY protection device, the compressor actively monitors motor winding temperature and operating parameters to prevent thermal damage. Supported by a 6 dm³ internal oil charge and a 200W-230V crankcase heater, the assembly ensures smooth mechanical lubrication and dependable startup under cold conditions.
