LNG Truck Fueling Station

Qingdao Lenado Intelligent Equipment Co., Ltd. is one of the most reliable manufacturers and suppliers of lng truck fueling 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 truck fueling station from our factory.

The LNG Truck Fueling Station – Heavy-Duty Dual-Pump Skid is engineered specifically for high-throughput logistics hubs, freight corridors, and heavy-duty truck fleets. Designed to eliminate bottlenecks and maximize station turnover, this integrated skid-mounted system delivers rapid, simultaneous refueling for two trucks at once, dramatically reducing vehicle downtime and queue wait times.

Built with PLC + Variable Frequency Drive (VFD) technology, the station operates in fully automatic unattended mode while delivering smooth, shock-free pump starts. Its compact outdoor skid design enables rapid deployment with minimal civil engineering, making it the ideal solution for logistics operators seeking reliability, speed, and low total cost of ownership.

1. Cryogenic Submerged Pumps (Dual)

Immersed directly in the LNG storage tank for optimal cooling and cavitation prevention

High-efficiency multi-stage centrifugal design

Optional Brands: American ACD, French Cryostar, or certified domestic manufacturers

Engineered for continuous heavy-duty cycling with extended MTBF

2. Temperature-Increasing Vaporizer (300 Nm³/h)

Ambient air-heated finned tube heat exchanger

Converts a controlled portion of LNG to gas for tank pressure regulation and station purge

Zero external power consumption; recovers cold energy efficiently

3. EAG (Emergency Air Gas) Vaporizer (150 Nm³/h)

Critical safety component for rapid depressurization during emergency shutdowns

Safely vents and vaporizes LNG without atmospheric liquid discharge

Ensures compliance with NFPA 52 / EN 13645 safety standards

4. PLC + VFD Control System

Industrial-grade programmable logic controller with touchscreen HMI

VFD Soft-Start: Eliminates electrical surge, reduces mechanical stress on pumps and piping, and cuts peak power demand by 20–30%

Real-time monitoring of flow, pressure, temperature, and liquid level

Automatic fault diagnosis, data logging, and remote communication capability (Modbus/4G optional)

LNG Storage Tank → Cryogenic Submerged Pumps → VFD-Regulated Flow → Dual Dispensing Nozzles → Heavy-Duty Truck Cylinders

Step-by-Step Operation:

1. Storage & Supply: LNG is stored at ~-162°C in a vacuum-insulated tank. The submerged pumps draw liquid directly from the tank base.

2. Pressurization & Metering: Dual pumps pressurize LNG to 0.8–1.2 MPa. High-precision cryogenic flow meters track exact dispensed volume.

3. Simultaneous Dispensing: Two independent dispensing lines allow two trucks to refuel concurrently. Operators simply connect the nozzles; the PLC auto-manages flow distribution.

4. Cold Energy Recovery: The temperature-increasing vaporizer uses ambient air to warm excess LNG, maintaining optimal tank pressure without external heaters.

5. Safety Venting: In emergency or overpressure scenarios, the EAG vaporizer instantly converts vented LNG to gas, preventing liquid release and ensuring safe atmospheric discharge.



✅ Key Advantages for Logistics Operators

Double the Throughput, Half the Wait Time

Dual-pump, dual-nozzle architecture enables simultaneous refueling of two heavy-duty trucks. Cuts average station dwell time by 40–50%, dramatically improving fleet turnover.

⚡ High-Flow Precision (Up to 350 L/min/Nozzle)

Optimized hydraulic design delivers rapid filling without pressure spikes or cavitation. A standard 1,000L truck cylinder fills in 3–4 minutes.

 VFD Energy Savings & Soft Start

Variable frequency control matches pump speed to real-time demand. Eliminates grid shock during startup, extends equipment life, and reduces monthly electricity costs by 20–30%.

️ High-Durability Cryogenic Pumps

Pumps are rated for continuous heavy-cycle operation. Optional premium brands (ACD/Cryostar) deliver 20,000+ hours MTBF, minimizing unplanned downtime.

Fully Automatic & Unattended

PLC automation handles sequencing, safety interlocks, and dispensing calculations. No constant operator presence required-ideal for 24/7 highway or depot stations.

 Rapid Outdoor Skid Deployment

Factory-tested, pre-piped, and pre-wired. Requires only foundation, power, and tank connection. Installation time: 3–5 days. Zero complex civil works.

Pro Tip: For stations targeting long-haul trucking networks, we recommend pairing the TYL-2×22 + Cryostar configuration with a card-payment POS module and cloud-based remote monitoring. This combination delivers enterprise-grade uptime, automated billing, and fleet management integration.
