Product Features
Factory Pre-Assembly
Pre-installed and tested piping, valves, and electrical systems minimize site civil works, eliminate field welding, and reduce commissioning duration.
Stable LNG Transfer Performance
A submerged cryogenic pump delivers continuous LNG transfer with reduced cavitation risk, stable outlet pressure, and reliable operation during frequent fueling cycles.
Operational Safety Systems
Configured for hazardous gas zones with emergency shutdown (ESD) valves, gas leak detection interfaces, thermal expansion relief routing, and pressure interlocks.
Boil-Off Gas (BOG) Management
Vacuum-insulated piping and low-leakage cryogenic valves limit ambient heat ingress and reduce boil-off gas generation during stand-by and transfer.
PLC Automation & Control
Automated system pressurization, VFD pump speed control, fault alarm logic, and data logging enable low-intervention station operation.
Containerized Transportability
Standard container dimensions match sea and road freight specifications, allowing equipment relocation and station capacity scaling.

FAQ
Q: How many LNG dispensers can one containerized pump skid support?
A: The configuration depends on pump capacity and station layout. A single skid can typically supply one or multiple dispensers, and customized solutions are available according to daily fueling demand.
Q: What site preparation is required before installation?
A: Normally only a concrete foundation, electrical power supply, LNG pipeline connection, grounding, and communication interfaces are required. Because the skid is factory assembled, on-site mechanical installation work is significantly reduced.
Q: Can this skid be integrated with an existing LNG fueling station?
A: Yes. The skid can be supplied as a standalone module for new projects or integrated into existing LNG stations during capacity expansion or equipment replacement.
Q: What spare parts are recommended for long-term operation?
A: Recommended spare parts typically include pump seals, valve repair kits, sensors, transmitters, filters, electrical components, and other wear parts based on the operating environment and maintenance schedule.
Q: What information should I provide to receive an accurate quotation?
A: To recommend the correct configuration, suppliers usually require:
Required LNG flow rate
Number of dispensers
Operating pressure
Local power supply
Installation location
Ambient temperature
Required certification (ATEX, IECEx, etc.)
Q: What is the typical manufacturing lead time?
A: Lead time depends on the project configuration, control system, and certification requirements. Standard configurations are generally delivered faster than fully customized systems.
Q: Do you provide commissioning and technical support overseas?
A: Yes. Technical documentation, remote commissioning support, operator training, and on-site service can be provided according to project requirements.
