Technical Features & Automation
High-Pressure Fuel Supply
Cryogenic LNG is pressurized by a high-pressure pump and vaporized into stable CNG at up to 25 MPa, ensuring consistent fueling performance during continuous operation.
Optimized Fueling Efficiency
The intelligent priority control system automatically switches between high-, medium-, and low-pressure storage banks, shortening vehicle filling time while maximizing gas utilization.
Flexible Project Configuration
Each station can be engineered according to daily fueling demand, available installation space, local regulations, and future expansion requirements.
Reduced Site Installation Time
Factory-integrated skid-mounted modules minimize on-site piping, wiring, and commissioning work, helping reduce project schedules and installation costs.
Intelligent Safety Monitoring
The PLC control system continuously monitors operating conditions and automatically activates alarms or emergency shutdown procedures if abnormal conditions are detected.

FAQ
Q: What information is required before requesting a quotation?
A: To recommend the most suitable solution, we typically require your estimated daily fueling demand, vehicle types and quantity, installation location, available utilities, local design standards, and any project-specific requirements.
Q: What factors determine the price of an L-CNG refueling station?
A: Project cost mainly depends on LNG storage capacity, daily fueling throughput, number of dispensers, automation level, certification requirements, and the scope of engineering services. Transportation and site conditions may also influence the overall investment.
Q: How long does manufacturing and delivery usually take?
A: Lead time varies depending on station capacity and customization level. Standard configurations generally require less production time, while large EPC projects may need additional engineering, factory testing, and documentation before shipment.
Q: Can the station comply with my country's regulations?
A: Yes. The station can be designed to meet applicable regional standards and certification requirements, including pressure equipment, explosion protection, and electrical safety regulations, subject to local project specifications.
Q: What maintenance is required after commissioning?
A: Routine maintenance includes periodic inspection of cryogenic pumps, valves, instrumentation, safety devices, and control systems. Preventive maintenance schedules and operating manuals are supplied with every project to help maximize equipment availability.
Q: Do you provide spare parts and long-term technical support?
A: Yes. We offer recommended spare parts packages, remote technical assistance, troubleshooting support, software updates where applicable, and engineering consultation throughout the equipment's service life.
Q: Can engineers provide overseas installation and commissioning?
A: Yes. Depending on project requirements, we can provide on-site technical supervision, commissioning support, operator training, and remote assistance to help ensure efficient project startup.
Q: Can the station be expanded in the future?
A: Yes. The modular design allows additional LNG storage, CNG storage cylinders, dispensers, or auxiliary equipment to be integrated as fueling demand increases, helping protect long-term investment without replacing the entire station.
