Refcomp SW3L-20000 R22 Cold Room Semi-Hermetic Screw Compressor

Bearings: Engineered for heavy-duty industrial freezing, this semi hermetic screw type compressor relies on a paired axial bearing layout designed to absorb combined radial and axial operating forces. Featuring high-precision rolling elements and specialized raceway profiles, the bearing system maintains tight running tolerances to support the high-capacity demands of the semi hermetic screw type compressor over extended operating cycles.

Capacity Regulation: To achieve precise thermal load adaptation under fluctuating operating conditions, this semi hermetic screw type compressor incorporates an internal slider valve supporting 4-step capacity regulation or continuous stepless control from 25% to full load. This advanced mechanism ensures tight internal sealing and minimizes gas bypass, optimizing the part-load efficiency of the semi hermetic screw type compressor across diverse refrigeration demands.

Suction Gas Filter: Protecting internal precision mechanisms from contamination, this semi hermetic screw type compressor integrates a built-in 100 μm high-precision suction filter directly within the housing. The filter actively screens out solid particles and debris from incoming refrigerant gas, safeguarding the internal components and extending the operational reliability of the semi hermetic screw type compressor.

Safety Valve: Engineered for maximum operational safety, this semi hermetic screw type compressor features a built-in internal safety valve connected between the high-pressure and low-pressure chambers. The high-standard engineering ensures precise opening pressure, stable full-flow release, and immediate reseating after pressure relief, effectively protecting the casing of the semi hermetic screw type compressor against unexpected overpressure spikes.
