Flexible Capacity Regulation
The SW3H-9000 refrigeration screw compressor supports four-stage capacity regulation at 25%, 50%, 75% and 100%, or stepless adjustment from 25% to 100%, allowing output to match changing cooling loads.
-
Compact High-Pressure Housing
The semi-hermetic screw compressor features a 25-bar working pressure design with optimized suction flow passages to reduce resistance and support motor cooling. Its compact construction integrates key components for convenient system installation.
-
INT69 SNY Motor Protection
An INT69 SNY protection module works with six series-connected PTC thermistors to monitor motor temperature and provide protection against overheating, reverse rotation and phase loss.
-
Integrated Pressure Safety Valve
An internal safety valve connects the high- and low-pressure sides, helping prevent excessive pressure differentials within the compressor housing and supporting reliable operation in industrial refrigeration systems.

Q1: What information is required to select the correct compressor for a refrigeration system?
For refrigeration screw compressor selection, provide the required cooling capacity, refrigerant, evaporating and condensing temperatures, and operating frequency. The SW3H-9000 has a displacement of 237 m³/h at 50 Hz and 284 m³/h at 60 Hz; actual cooling capacity should be confirmed using manufacturer performance data.
-
Q2: How should capacity regulation be matched to changing refrigeration loads?
Choose between four-stage regulation and stepless capacity adjustment according to the system's load profile. Confirm that the refrigeration controller supports the selected regulation method before finalizing the system configuration.
-
Q3: What electrical requirements should be checked before commissioning?
The standard motor uses star-delta starting with 400V/3/50Hz or 460V/3/60Hz power supplies. The specified star-delta starting current is 193/580 A, and the maximum operating current is 140 A; verify starter selection, cable sizing and electrical protection before startup.
-
Q4: What should I check if the refrigeration screw compressor trips during operation?
Check the INT69 SNY protection indication, PTC sensor circuit, phase sequence and motor operating temperature. Identify and correct the underlying electrical or operating fault before resetting the protection module and restarting.
