For screw compressor HVAC applications, RefComp's 5/6 asymmetric rotor profile supports smooth compression with reduced gas pulsation, vibration and operating noise.
The built-in multi-stage oil separator uses layered oil-mist filtration to achieve a stated separation efficiency of 99.85%, helping the air conditioning screw compressor minimize oil carryover and maintain internal lubrication.
This semi-hermetic screw compressor features an internal safety valve connecting the high- and low-pressure sides, helping protect the compressor housing against excessive pressure differentials.
The RefComp screw compressor uses an INT69 SNY module with six series-connected PTC thermistors to monitor motor temperature and provide protection against overheating, reverse rotation and phase loss.

Q1: What operating data should I provide when selecting the class="lazy" src="/myres/images/load_icon.gif" data-original-S(W)-503 for an HVAC system?
For screw compressor HVAC 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)-503 has a displacement of 562 m³/h at 50 Hz and 674 m³/h at 60 Hz, while actual cooling capacity must be verified against the manufacturer's performance data.
Q2: How can the class="lazy" src="/myres/images/load_icon.gif" data-original-S(W)-503 handle fluctuating cooling demands?
This HVAC screw compressor supports 100%, 75%, 50% and 25% capacity regulation stages, with stepless adjustment from 100% to 25%. Confirm the supplied capacity control configuration and controller compatibility to ensure proper operation under varying loads.
Q3: What should be verified before connecting the class="lazy" src="/myres/images/load_icon.gif" data-original-S(W)-503 to an existing refrigeration system?
Check the 105.5 mm (4-1/8") suction and 80.0 mm (3-1/8") discharge connections against the existing pipework. Verify the motor starting arrangement, electrical protection and compatibility with the standard 400V/3/50Hz or 460V/3/60Hz power supply before installation.
Q4: What should I check if the class="lazy" src="/myres/images/load_icon.gif" data-original-S(W)-503 operates with unusually high discharge temperatures?
In screw compressor HVAC systems, elevated discharge temperatures may result from excessive condensing pressure, abnormal suction conditions or insufficient refrigerant flow. Check the condenser performance, refrigerant charge and actual operating conditions against the manufacturer's specified limits before continuing operation.
