Product Overview

MINGXIN’s LNG Vehicle Cylinders are high-performance, cryogenic on-board fuel storage systems engineered specifically for heavy-duty commercial vehicles. Designed to safely store Liquefied Natural Gas (LNG) at -162°C, these cylinders empower logistics fleets, city buses, and heavy-duty trucks to transition from traditional diesel to clean, cost-effective natural gas. By utilizing advanced thermal insulation and a rugged, vibration-resistant structure, MINGXIN provides the ultimate solution for extending driving range while significantly reducing carbon emissions and fuel costs.

Key Features & Design Highlights

  • Exceptional Thermal Insulation: Wrapped with high-vacuum multi-layer super insulation materials, these cylinders guarantee an exceptionally low daily evaporation rate. This extended "holding time" virtually eliminates Boil-Off Gas (BOG) venting, preventing fuel loss even when the vehicle is parked for several days.

  • Vibration & Shock Resistant: Engineered for the harshest road conditions. The inner vessel features a specialized multi-point suspension system designed to absorb extreme shocks and vibrations, ensuring structural integrity and safety during long-haul highway transit or off-road mining operations.

  • Integrated Safety System: Equipped with a comprehensive dual-safety relief valve system. In the event of abnormal pressure buildup, the primary and secondary safety valves automatically vent to prevent over-pressurization.

  • Ergonomic Valve Shroud: All critical components—including the fill receptacle, vapor return valve, liquid level gauge, pressure gauge, and economizer regulator—are neatly integrated into a protective, easily accessible stainless steel shroud at the end of the cylinder for quick and safe refueling.

  • Lightweight for Maximum Payload: Constructed entirely from premium S30408 / 304L stainless steel, the cylinder is optimized to maintain high strength while reducing tare weight, ensuring that your vehicle's payload capacity is not compromised.
