Frequently Asked Questions

What details should be provided when selecting this refrigeration screw compressor for a system build?

Please specify your target cooling capacity, operating evaporating and condensing temperatures, refrigerant selection, and project site electrical specifications.

What piping precautions should be observed when connecting this compressor to the refrigeration circuit?

Match connections to the 80.0 mm discharge and 105.5 mm suction lines, install rigid supports to prevent line vibration, and verify check valve alignment to avoid reverse rotation on shutdown.

What pre-start checks are essential before initial system commissioning?

Confirm that the 20 dm³ oil charge is visible at the proper level in the sight glass, verify control loop wiring for the INT69 SNY protection module, and ensure the 275W crankcase heater has energized for adequate time.

What routine maintenance steps help ensure long-term operational stability?

Inspect the 100 µm suction filter element for pressure drop, check oil cleanliness and differential pressure, and verify motor overload safety circuits during scheduled maintenance cycles.
