Qingdao Lenado Intelligent Equipment Co., Ltd. is one of the most reliable manufacturers and suppliers of lng refuelling station in China. With a professional production team, we are able to meet the needs of the majority of our customers. Welcome to wholesale bulk customized lng refuelling station from our factory.
Product Overview
The LNG Refuelling Station is a standard integrated skid-mounted LNG dispensing system specifically designed for high-demand applications including bus depots, logistics centers, and heavy-duty truck terminals. Featuring a dual-pump configuration with simultaneous dual-nozzle dispensing capability, this station delivers exceptional filling speeds and operational reliability for commercial fleet operations.
Built with advanced PLC + variable frequency control technology, the system operates in fully automatic unattended mode, significantly reducing labor costs while ensuring consistent, safe operations. The outdoor-rated, weatherproof enclosure design makes it ideal for 24/7 operations in various environmental conditions.

Detailed Process
Storage: LNG is stored in an external vacuum-insulated storage tank at approximately -162°C and low pressure (0.3-0.8 MPa)
Pumping: The submerged cryogenic pumps draw LNG from the storage tank and pressurize it to dispensing pressure (0.8-1.2 MPa)
Metering & Control: High-precision cryogenic flow meters measure the exact volume dispensed, while the PLC system controls pump speed via VFD
Dispensing: LNG flows through insulated hoses to the dispensing nozzles, where operators connect to vehicle receptacles
Vaporization: The temperature-increasing vaporizer uses ambient air heat to warm a portion of LNG, providing boil-off gas for tank pressure management
Safety: The EAG vaporizer handles emergency depressurization, safely converting LNG to gas before atmospheric release
