LNG Single Gun Refueling Machine

The LNG Single Gun Refueling Machine is a low-temperature liquid dispensing unit designed for LNG and compatible cryogenic media such as liquid nitrogen. It integrates a cryogenic filling hose, liquid filling gun, gas recovery line, metering system, and control unit for controlled liquid transfer.

The system uses stainless steel low-temperature hoses and dedicated cryogenic filling components to handle pipeline temperatures from -196°C to 55°C.
The adjustable flow range accommodates different filling requirements while supporting controlled transfer for commercial and industrial applications.
The dispenser measures liquid by mass, with a minimum reading division of 0.01 kg. Single and cumulative measurement functions support transaction records and operational monitoring.

The LNG Single Gun Refueling Machine controls the transfer of cryogenic liquid from the storage system to the receiving vehicle or equipment through the dedicated filling line.
During filling, LNG passes through the cryogenic liquid pipeline and filling gun while the metering system records the transferred quantity by mass. The gas recovery line provides a separate return path for the gas phase generated or displaced during the filling process.
The operator can monitor the filling quantity and use the preset function to control the target filling quantity or transaction value. After filling, the liquid and gas-phase connections can be disconnected through their respective filling and quick-connect interfaces.

LNG Fleet Depots
Suitable for controlled LNG dispensing at centralized fleet fueling facilities.
Industrial LNG Facilities
Used for liquid LNG transfer and dispensing where a metered filling interface is required.
Cryogenic Liquid Distribution
Applicable to controlled dispensing systems for compatible cryogenic liquids.
Liquid Nitrogen Filling Systems
Can be configured for liquid nitrogen applications when the complete system, materials, seals, and filling components are confirmed to be compatible.
Energy and Cryogenic Equipment Projects
Suitable for integration into customized LNG or cryogenic liquid filling installations.
