Gas compression (with screw-type compressor)

Screw compressors are generally installed at the inlet of purification units to boost normal-pressure or slightly positive-pressure biogas to the pressure suitable for membrane module purification. Featuring low cost and high efficiency, they serve as the optimal choice for biogas pressurization.

Screw Compressor Parameters

Inlet Pressure: Atmospheric pressure / Slightly positive pressure

 Discharge Pressure: ≤4 MPa

Medium: Biogas

Transmission Mode: Direct motor coupling

Cooling Type: Air cooling / Water cooling

Control System: PLC logic control

Mounting Type: Chassis mounting on skid base

Product Advantages

1. Stable & Durable: Free of reciprocating impact structures with minimal wear. Capable of long-term full-load continuous operation, perfectly suited for heavy-duty industrial working conditions.

2. Energy-Saving & High Efficiency: High volumetric efficiency of rotors. Variable frequency models automatically adjust power output according to load with low no-load loss, delivering outstanding energy-saving performance.

3. Low Vibration & Low Noise: Smooth rotary compression operation with slight vibration and low noise. No special foundation required for easy installation.

4. Hassle-Free Maintenance: Low overall failure rate and long service life. Only regular replacement of standard consumables is needed, resulting in low long-term operating costs.

5. High-Quality Gas Supply: Multi-stage purification and separation design ensures stable discharge pressure and high gas cleanliness, meeting both standard and precision gas supply requirements.
