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
