The refrigeration screw compressor features a 25-bar housing with optimized internal gas passages to reduce flow resistance. Its compact structure integrates the suction filter, shut-off valve and temperature sensor.
This semi-hermetic screw compressor uses matched bearing assemblies to support axial and radial rotor loads. Precision rolling elements and wear-resistant raceways help minimize friction, vibration and operating noise.
A built-in 100 μm suction filter captures impurities from incoming refrigerant gas, helping protect the motor. Its accessible suction-side position allows convenient inspection and replacement during maintenance.
The refrigeration screw compressor incorporates an internal safety valve connecting the high- and low-pressure sides, helping prevent excessive pressure differentials and supporting safer operation.

Q1: How can I determine whether the class="lazy" src="/myres/images/load_icon.gif" data-original-S(W)-553 meets my refrigeration capacity requirements?
For refrigeration screw compressor selection, provide the required cooling capacity, refrigerant, evaporating and condensing temperatures, and operating frequency. The class="lazy" src="/myres/images/load_icon.gif" data-original-S(W)-553 has a displacement of 600 m³/h at 50 Hz and 720 m³/h at 60 Hz, but actual cooling performance must be verified against the manufacturer's selection data.
Q2: What should be considered when connecting the class="lazy" src="/myres/images/load_icon.gif" data-original-S(W)-553 to an economizer system?
The RefComp screw compressor provides a 42 mm economizer connection and a 10 mm liquid injection connection. Verify the economizer piping arrangement, control requirements and operating conditions before integrating these connections into the refrigeration circuit.
Q3: What preparations are necessary before the first startup of the class="lazy" src="/myres/images/load_icon.gif" data-original-S(W)-553?
Check the oil level, electrical connections, motor protection settings and refrigerant piping. Confirm that the 275 W crankcase heater is operating as required, and complete system leak testing and evacuation before commissioning.
Q4: What should I investigate if the class="lazy" src="/myres/images/load_icon.gif" data-original-S(W)-553 delivers insufficient cooling capacity?
Check the evaporating and condensing pressures, refrigerant supply, capacity control settings and actual operating load. Compare the measured conditions with the manufacturer's performance data to identify possible system or compressor operating issues.
