L-CNG Refueling Machine

The L-CNG Refueling Machine integrates LNG direct filling and LNG-to-CNG compression systems for stations serving both LNG and CNG vehicles. It uses a low-temperature high-pressure LNG pump, gasifier, high-pressure storage cylinders, sequence control panel, and dual fuel dispensers to provide metered vehicle refueling.

Final configuration, flow capacity, pressure rating, electrical requirements, and station layout can be confirmed according to project conditions and applicable local regulations.

Dual LNG & CNG Refueling
Supports both LNG liquid filling and CNG gas filling in one integrated station system, reducing the need for separate refueling equipment.
Efficient LNG-to-CNG Conversion
LNG is pressurized and vaporized through the high-pressure gasifier before entering the high-pressure storage system, enabling CNG production from stored LNG.
High-Pressure Gas Storage
The CNG storage cylinder group is designed for a working pressure of 25 MPa and provides buffer storage for stable vehicle refueling.
Sequence-Controlled Gas Distribution
The CNG sequence control panel manages gas flow between the storage cylinder group and dispenser to improve filling efficiency and pressure utilization.

For CNG production, LNG is extracted from the storage tank by the low-temperature high-pressure pump. The pressurized LNG then passes through the high-pressure air-temperature gasifier, where it is converted from liquid LNG into high-pressure natural gas. The resulting CNG enters the high-pressure gas storage cylinder group through the sequence control panel.
During vehicle refueling, the sequence control system manages gas distribution from the storage cylinders to the CNG dispenser. The dispenser meters and delivers CNG to the vehicle at the required filling pressure.
For LNG vehicles, LNG can be supplied directly from the low-temperature side through the dedicated LNG filling line and filling gun.
