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.
