Core Features

Wide Operating Temperature Range

Operates reliably at -50℃ evaporation temperature (compatible with R22/R404A) and up to 50℃ condensing temperature, suitable for cold storage and heat pump applications.

Thermal-resistant coatings on valve plates and a dedicated oil cooling loop prevent overheating in high-temperature environments.

Low Vibration & Noise

Features dynamic balancing technology that reduces vibration to <3.5 mm/s, minimizing stress on pipelines and installations.

Noise levels reach only 72 dB(A) at 1 meter, complying with ISO 3744 standards—ideal for noise-sensitive industrial areas.

Flexible Capacity & Power Compatibility

Offers 25%-100% stepless capacity regulation (optional) to match variable cooling demands, reducing energy waste.

Supports dual power supplies: 380V-420V (3PH/50Hz) and 440V-480V (3PH/60Hz), adapting to global industrial power standards.
