Refcomp SW3L-13000 130HP R134a Refrigeration Screw Compressor

Bearings: This high-efficiency refrigeration screw compressor is engineered with a paired axial bearing layout that effectively absorbs combined radial and axial operating forces. The high-precision rolling elements and specialized raceway profiles maintain tight running tolerances and low friction, delivering exceptional durability with a design bearing lifespan reaching up to 40,000 hours under t0=-35/40°C R507A conditions.

Suction Gas Filter: To protect internal components from contamination, this refrigeration screw compressor incorporates a high-precision 100 μm suction filter built directly inside the housing. It effectively collects particulate matter and solid debris from incoming suction gas, safeguarding the precision rotors and motor chamber against mechanical wear.

Safety Valve: Designed for maximum operational safety, the refrigeration screw compressor features an internal safety valve connected between the high and low-pressure chambers. The high-standard sealing structure ensures precise opening, stable full flow, and immediate reseating after pressure relief to prevent dangerous housing overpressure.

Motor: The custom motor supports part-winding start or Y/Δ start configurations to ensure low starting current and low energy consumption across regional power grids. Constructed with materials compatible with R22, R134a, R507A, R404A, and R410A refrigerants, it utilizes cold suction gas flowing through optimized internal channels to maintain continuous thermal stability.
