The continuous, progressive scroll compression process minimizes clearance volume losses and suction/discharge pressure losses.
Both volumetric efficiency and adiabatic efficiency reach industry-leading levels.
The flexible scroll design adapts to minor pressure fluctuations, further reducing internal leakage.
Digital scroll and variable frequency technology enable stepless capacity modulation from 10% to 100%, delivering outstanding energy efficiency, especially under part-load conditions.
Exceptional Reliability
Utilizes a high-strength cast iron body and precision-machined crankshaft/connecting rod.
Fewer moving parts (only orbiting and fixed scrolls), eliminating vulnerable components like suction and discharge valves.
Low mechanical wear, extremely low failure rate, and significantly longer lifespan than traditional reciprocating compressors.
The internal motor features special insulation materials and vacuum impregnation, offering excellent heat and voltage surge resistance.
II. Operational Performance Advantages
Low Noise and Vibration
Smooth operation as the continuous compression process replaces intermittent impacts.
Significantly reduces noise and vibration levels, enhancing user experience.
Equipped with bottom elastic vibration dampers to effectively minimize vibration transmission.
Strong Starting Capability
Ensures reliable start-up even under conditions with significant pressure differentials.
Crucial for heat pump system restart after defrosting in extreme cold weather.
Good oil and liquid return tolerance improves overall system operational stability.
III. Maintenance and Safety Advantages
