Refcomp SRC-S(W)-413 SRC-S-413-L4 Heavy-Duty Screw Refrigeration Compressor
Heavy-Duty Screw Refrigeration Compressor
,Refcomp SRC-S-413 Screw Compressor
,Screw Type Compressor
RefComp's 5/6 asymmetric rotor profile helps the screw refrigeration compressor achieve smooth compression with reduced gas pulsation, vibration and operating noise.
This industrial refrigeration screw compressor incorporates a multi-stage oil separator with layered oil-mist filtration, achieving a stated separation efficiency of 99.85% while reducing oil carryover and maintaining internal lubrication.
The screw refrigeration compressor features a 25-bar housing with optimized internal gas passages to reduce flow resistance. Its compact construction integrates the suction filter, shut-off valve and temperature sensor.
Six series-connected PTC thermistors work with the INT69 SNY module to provide motor temperature monitoring and protection against overheating, reverse rotation and phase loss in this semi-hermetic screw compressor.

Q1: What information is required to select the SRC-S(W)-413 screw refrigeration compressor?
Provide the required cooling capacity, refrigerant, evaporating and condensing temperatures, and operating frequency. The model has a displacement of 445 m³/h at 50 Hz and 534 m³/h at 60 Hz, but actual cooling capacity must be verified against the manufacturer's performance data.
Q2: How can the SRC-S(W)-413 be integrated with a refrigeration capacity controller?
The SRC-S series specifies 100%, 75%, 50% and 25% capacity stages, with stepless control from 100% to 25%. Confirm the supplied regulation configuration, controller compatibility and required safety interlocks before integrating the refrigeration screw compressor into the control system.
Q3: What should be verified before installing the SRC-S(W)-413?
Check the 92.5 mm suction and 80.0 mm discharge connections, mounting arrangement and available service clearance. Confirm the standard three-phase power supply of 400V/50Hz or 460V/60Hz, and complete the required piping inspection, leak testing and evacuation before commissioning.
Q4: What should I check if the compressor's motor protection module trips repeatedly?
Inspect the power supply, phase sequence, motor temperature and PTC sensor circuit to identify the cause. Do not bypass the protection module; resolve the fault and follow the manufacturer's reset procedure before restarting.
