A CNG (Compressed Natural Gas) supply system is a complete turnkey unit that purifies natural gas, compresses it to 20–25 MPa for storage in specialized high-pressure vessels, and then delivers a stable gas supply to various end-users through processes such as pressure reduction, regulation, and metering. Functioning as a "virtual pipeline," it effectively addresses the challenge of providing gas to areas beyond the reach of pipeline infrastructure.
Its core operating principle involves processing high-pressure gas from storage cylinders through regulation, metering, and odorization before feeding it into the natural gas distribution network or directly supplying it to engines for combustion.
As a high-pressure gas stored at ambient temperature, CNG is ideally suited for medium-to-short-distance transportation and small-to-medium scale consumers.
