Description:
Also known as CNG Compressor, the ordinary natural gas compressors have type L, ZW, D, W and so on with their own characteristics and advantages.

Features of L Type Natural Gas Compressor:
1. L type Compressor is designed for small or middle sized conventional CNG stations.
2. This CNG compressor has many advantages, such as compact structure, appealing configuration, energy saving, and less oil lubricating.
4. Gas pipelines, water pipelines and meter lines integrally link the main body and coolers.
5. Air cooling or water cooling is available.

Features of ZW Type Natural Gas Compressor:
1. This type is a middle speed compressor with upright structure.
2. Output efficiency is increased by the non-balance sect designation.
3. With oil-free lubricating, ZW type can leads to stable performance and less vibration.

Features of D Type and 4M Type (Horizontal Structured) Compressor
1. The horizontal natural gas compressor is a middle speed compressor with skid-mounted package.
2. It mainly applies to CNG mother station with large supply production.
3. D type CNG compressor can operate stably and reliably due to the horizontal balanced structure.
4. The horizontal structured natural gas compressor with less vibration and noise is easy to maintain.
5. Average working speed of piston is 2.7m/s, and the PV value is very low under the same combined rod load.
6. It can prolong service life of wearing parts and reduce the running costs with high reliability.
7. Direct driving and flying wheel promote machine operate quickly and effectively.

Functions of PLC Cabinet:
1. PLC cabinet can provide over/less pressure protection for inlet pressure.
2. PLC cabinet can offer over-pressure protection for discharge of every stage.
3. PLC cabinet can support over-temperature protection for last stage outlet and lubricant oil.
4. PLC cabinet can give less-pressure protection for cooling water.
5. PLC cabinet can provide over-load protection for the motor.
6. PLC cabinet can automatically start or stop.
