With a professional production team, we are able to meet the needs of the majority of our customers. Welcome to wholesale bulk customized lng filling station from our factory.
Product Overview
A modern LNG filling station requires more than just a pump; it demands a fully integrated, turnkey ecosystem that ensures safety, efficiency, and uninterrupted fleet operations. Our Complete LNG Filling Station Solution positions our advanced skid-mounted pumping unit as the operational heart of your station, seamlessly integrated with cryogenic storage, precision dispensing, and intelligent safety systems.
Designed for bus depots, logistics hubs, and highway service corridors, this solution delivers PLC + Variable Frequency Drive (VFD) automation, fully unattended operation, and rapid outdoor deployment. Whether you're launching a new site or upgrading existing infrastructure, our modular approach eliminates complex civil works, reduces commissioning time, and guarantees long-term ROI.
Complete LNG Filling Station Solution – Skid-Mounted Core Unit
SEO Information
Title: Complete LNG Filling Station Solution | Turnkey Skid-Mounted Core Unit | PLC+VFD
Meta Description: Deliver a fully integrated LNG filling station with our advanced skid-mounted pumping core. Features PLC+VFD control, dual-pump redundancy (up to 350 L/min), premium ACD/Cryostar pump options, and complete station ecosystem integration. Fully automatic & outdoor-ready.
Station Process Flow
Our solution manages the complete LNG delivery chain from tanker arrival to vehicle departure:
Unloading Stage: LNG tanker connects to the unloading station. Cryogenic flexible hoses transfer liquid to the main storage tank.
Cryogenic Storage: Vacuum-insulated storage tanks maintain LNG at ~-162°C and low pressure (0.3–0.8 MPa), minimizing boil-off losses.
Core Pumping (Skid Unit): Submerged cryogenic pumps draw LNG from the tank base, pressurize it to dispensing levels (0.8–1.2 MPa), and route it through precision flow meters.
Dispensing: LNG flows to outdoor dispensers where operators connect dual-hose nozzles to vehicle receptacles. Mass flow meters ensure billing-grade accuracy.
Vehicle Fueling: LNG enters onboard cylinders, completing the refueling cycle. Average fill time: 5–12 minutes depending on vehicle capacity.
Key Advantages of Our Solution
VFD-Driven Energy Efficiency
Variable frequency technology matches pump speed to real-time demand. Eliminates grid surge during startup, reduces peak power consumption by 20–30%, and extends motor lifespan.
Dual-Pump High Availability
Two independent submerged pumps operate simultaneously or in standby mode. If one requires maintenance, the other continues at 50% capacity, ensuring zero station downtime.
International-Grade Pump Options
Choose from American ACD or French Cryostar submerged pumps for extreme-duty cycles, or opt for certified domestic alternatives for optimized CAPEX. All rated for continuous LNG service at -162°C.
Fully Automatic & Unattended
PLC automation handles sequencing, safety interlocks, pressure regulation, and fault diagnostics. Touchscreen HMI provides real-time status; no constant operator presence required.
Modular Skid Design
Factory-tested, pre-wired, and pre-piped. Requires only foundation, power, and tank connection. Cuts installation time by 60% compared to traditional stick-built stations.
Cold Energy Recovery
Integrated temperature-increasing and EAG vaporizers utilize ambient air heat, eliminating external energy consumption while safely managing tank pressure and emergency venting.
