CNG Compressor
The MINNUO CNG compressor is a reciprocating piston-type compression device specifically designed for demanding industrial environments. It is capable of handling multiple mediums, including natural gas, sour gases, and biogas.
With its high-pressure output and wide flow range, it meets the full spectrum of requirements from urban refueling stations to offshore platforms. The ISO-certified heavy-duty structural design ensures stable operation in extreme environments, 24/7.
High-Pressure CNG Compressor
The MINNUO CNG compressor utilizes reciprocating piston technology to achieve efficient compression through a four-step cycle:
- Suction: The piston moves backward to expand the cylinder volume, opening the intake valve, allowing natural gas to enter the cylinder.
- Compression: The piston moves forward to reduce the volume, gradually increasing the gas pressure to the preset value.
- Exhaust: The high-pressure gas pushes open the exhaust valve, transferring the gas to the downstream system.
- Expansion: The piston resets, preparing for the next cycle. This continuous reciprocating motion ensures stable, continuous gas compression output.
