Condenser & Evaporator
Uses high-efficiency shell-and-tube or evaporative cooling. Siphon structure in the evaporator ensures saturated refrigerant supply and high heat transfer factors.
Throttle Valve & Shell
Advanced imported control valve groups for automatic adjustment. 3D printed metal tools ensure high casting accuracy and low exhaust noise.
Oil Management
Patented oil-gas separator reaches less than 5PPM oil content. Efficient oil cooler design reduces maintenance needs.
Fully automated control with PID energy regulation, real-time data monitoring, and historical alarm query. Supports Modbus RTU, Modbus TCP, and Profinet protocols.
Widely used in food freezing, process cooling, gas liquefaction, building aggregate cooling, scientific research, and mine heat hazard treatment. Real-time cloud monitoring and adjustable volume-reduction ratios are available.
Our high-efficiency screw compressors have won numerous first prizes for scientific and technological progress. We maintain over 60% domestic market share in the cold chain field and serve customers in over 80 countries.
