Our Advantages

Two-stage Screw Compressor Units

Two-stage Screw Compressor Unit

1. The unit adopts a modular design, compact structure, reasonable layout, and reliable operation.

2. Circulation mode: incomplete cooling in the middle of two-stage compression and one-stage throttling, low-pressure stage with economizer

3. High Reliability

– Sliding bearing, long operating life
– Less wearing parts, smooth operation, suitable for long-term operation

4. High efficiency

The exhaust temperature of the unit is low, high volumetric efficiency
– World’s leading screw compressor rotor profile, high efficiency
– Energy step-less adjustment
– Adopt a high-efficiency oil separator and high-efficiency oil cooler to ensure low oil consumption and high heat exchange
the efficiency of the unit

5. Intellectualized:

– Manual control and microcomputer automatic control
– The special microcomputer controller, strong control capability. And realize modulation and networking

Single-stage Screw Compressor Units

Single-stage Screw Compressor Unit

1. Perfect structure and reliable performance
– Single compressor realized two-stage compression, compact structure, reasonable layout, nice appearance, and simplifies the configuration of the refrigeration system. (can be equipped with Bitzer/Mycom compressor)
– Imported mechanical seal, simple structure, easy installation, excellent sealing performance to ensure continuous and
long-term stable operation of the compressor
– Advanced processing equipment and technology to ensure more accurate processing accuracy and higher efficiency, improve the reliability of the compressor operation
– The whole rolling has low noise, small vibration, rotor precise, which ensures continuous operation and long life of the
compressor.
– Oil cooler can adopt water cooling or thermal siphon cooling

 

2. High efficiency and energy saving
– Small single-stage pressure ratio and high COP value in large pressure ratio condition
– World’s leading screw compressor rotor profile, high efficiency
– Compressor differential pressure oil supply, saving power consumption, improving the reliability of the oil pump
– Both high and low stages use step-less adjustment energy to ensure efficient operation
– Adopting high efficient oil separator to ensure that oil fuel consumption is ≤5ppm, ensuring unit with low fuel consumption
– High precision suction and oil filter element

3. Ultra low-temperature screw compressor unit
– Evaporative temperature is as low as -55 ℃

4. Intellectualized
– Automatic microcomputer control, run faster, more reliable, more powerful control, has achieved a modular, network, and also has a beautiful appearance, convenient operation, friendly interface, etc
