LNG Mobile Refueling Machine

The LNG Mobile Refueling Machine is a trailer-mounted LNG storage and dispensing system designed for flexible fuel supply where a fixed LNG station is unavailable or temporary fueling capacity is required. It integrates an LNG storage tank, metering and dispensing system, pressure-building gasifier, control system, and safety devices on a semi-trailer or truck-direct trailer chassis.

A semi-trailer or truck-direct trailer configuration allows the equipment to be transported between fueling locations and deployed for temporary, remote, or supplementary LNG supply.
An integrated small self-pressurized gasifier helps maintain the required tank pressure during dispensing and supports stable LNG transfer without requiring a separate external pressure-building system.
The control interface supports functions such as preset quantitative filling, amount setting, operating-status monitoring, and data uploading, helping operators manage routine fueling operations.

LNG is a cryogenic and flammable fuel, so the mobile refueling unit must be operated according to the applicable LNG handling, pressure equipment, electrical, transportation, and fire-safety requirements.
Key considerations include:

• Installation and operation should follow the approved equipment documentation and applicable local regulations.
• The refueling area should provide adequate ventilation and appropriate separation from ignition sources.
• Emergency shutdown functions should be accessible to trained operators.
• LNG hoses, valves, connectors, and seals should be inspected according to the operating and maintenance schedule.
• Gas detection and other safety devices should be tested periodically.
• Operators should receive appropriate training in LNG transfer, cryogenic hazards, emergency procedures, and equipment operation.
