- Precision Sleeve Bearings: High-precision sleeve bearings and thrust washers minimize shaft wear, reduce operating noise, and support a long service life of 50,000 to 80,000 hours.
- Internal Safety Protection: As a reliable semi-hermetic compressor, it features an internal safety valve connecting the high- and low-pressure chambers to safely balance internal pressure surges.
- Versatile Motor Design: Engineered with flexible multi-voltage and frequency support to deliver low starting current and stable performance across diverse low-temperature applications.
- Optimized Refrigerant Flow: This semi-hermetic compressor utilizes suction gas flow channels to efficiently cool internal motor windings before compression, enhancing overall efficiency.

A: Selection requires confirming the required cooling capacity, evaporation and condensation temperatures, refrigerant type, power supply compatibility, and operational load.
A: Ensure site connections match the 16 mm (5/8″) discharge pipe and 28 mm (1-1/8″) suction pipe to prevent excessive pressure drops in the suction line.
A: The 230V-120W PTC crankcase heater keeps the oil warm when idle, preventing liquid refrigerant condensation and ensuring immediate lubrication upon startup.
A: Check that the supply voltage matches motor ratings, verify thermal protection wiring, and ensure the 49 A starting current and 10 A maximum operating current limits are observed.
