Features

Designed for low-temperature refrigeration conditions with evaporation temperatures below -25°C, offering significantly higher efficiency compared to single-stage screw compressor units with economizers.
Versatile ratio options tailored to different conditions and refrigerants, with R717 high-to-low-pressure ratios ranging from 3 to 4 and R507A ratios from 2 to 3.
Energy regulation devices on both high- and low-pressure stages ensure efficient and economical operation across all low-temperature conditions.
Features staged startup for high- and low-pressure compressors, resulting in reduced startup current.
Low-pressure compressors utilize differential pressure oil supply for enhanced performance.
High-pressure stage can operate independently for rapid cooling with high efficiency.
Standard configuration includes automated controls to minimize manual intervention and improve operational efficiency.
Multiple configuration options available to meet specific user requirements.
