PRODUCT ADVANTAGE
2-STAGE SEMI-HERMETIC RECIPROCATING COMPRESSOR
- The right choice for extensive range of low-temperature application, 7 models available
- Adopt Bitzer second generation of 2-stage compressor, highly efficient and reliable
- The refrigerant first undergoes initial compression in the low-pressure cylinder, then cools down by intermediate cooler liquid injection, and finally enters the high-pressure cylinder for secondary compression. Enhanced efficiency, high refrigeration capacity, and low energy requirement.
- Evaporation Temperature is -50℃ for R22 and -70℃ for R404a
PRACTICAL DESIGN
- Feature a system-optimized condenser
- Come with a constant pressure valve, which adjusts the steam flow rate according to the outlet pressure, to avoid the suction pressure at the inlet of the compressor from exceeding the specified value, prevent the compressor from operating under high suction pressure, and hence provide overload protection for compressor motor
- High quality refrigeration parts and comprehensive protection
- Wide range of refrigerants
- Easy installation, commissioning and maintenance
COST PERFORMANCE
- Very low operating costs due to outstanding high energy efficiency
- Long lifetime due to high robustness
- Low maintenance costs by service-friendly design
