Frequently Asked Questions
Q: What details are required when selecting this screw refrigeration compressor for a new refrigeration plant?
A: Selection requires confirming the required cooling capacity, evaporating and condensing temperatures, target refrigerant, and project electrical power specifications.
Q: What piping considerations are essential during installation?
A: Ensure precise connection to the 80.0 mm discharge and 105.5 mm suction ports, provide rigid pipe anchoring to reduce vibration, and verify discharge check valve positioning to prevent liquid return on shutdown.
Q: What pre-commissioning checks must be performed prior to starting the compressor?
A: Check that the 16 dm³ oil charge is visible in the sight glass, verify proper signal wiring to the INT69 SNY protection module, and ensure the crankcase heater has energized for sufficient pre-heating time.
Q: What routine maintenance practices ensure stable continuous operation?
A: Inspect the internal suction filter for pressure drop, monitor oil differential pressure across internal flow channels, and check motor thermal protection circuits during periodic maintenance.
