Open CNG Gas Station | Outdoor Skid-Mounted Natural Gas Refueling Systems

✅ Weatherproof Outdoor Enclosure | ✅ Noise Reduction <75dB @ 1m | ✅ Modular Skid Design | ✅ Quick Deployment & Easy Maintenance | ✅ ATEX/CE Certified Explosion Protection

Our open CNG gas station solutions deliver robust, outdoor-ready natural gas refueling systems engineered for harsh environments and rapid deployment. Featuring integrated skid-mounted compressors housed in weatherproof, sound-insulated enclosures, these stations operate reliably in temperatures from -40°C to +55°C without requiring permanent buildings or extensive civil works.

The modular box design incorporates multi-layer acoustic insulation (high-frequency absorption + low-frequency blocking), electrostatic-sprayed corrosion-resistant panels, and an integrated rainproof roof with sealed joints. All electrical components meet ExdeIIBT3/ExdIIBT4 explosion-proof standards, while the water-circulating air cooling system ensures stable operation in extreme climates using ethylene glycol antifreeze.

Ideal for mining sites, ports, construction camps, and remote fleet depots, our open CNG gas stations combine 2,500 Nm³/h compression capacity with fully automated PLC control, remote monitoring via TCP/IP, and dual-system redundancy for uninterrupted 24/7 service.

1. Weatherproof Outdoor Enclosure Design

The integrated skid box features an electrostatic-sprayed exterior (after pickling, rust removal, and sandblasting) for superior corrosion resistance. Panel joints and door seams are fully sealed to prevent water ingress and noise leakage. The integrated roof design eliminates leakage risks, enabling reliable operation in rain, snow, dust, and high-humidity environments.

2. Advanced Noise Reduction <75dB @ 1m

Multi-layer sound insulation materials inside the enclosure absorb high-frequency noise and block low-frequency transmission. The frame structure minimizes panel vibration, while the self-ventilating design maintains cooling efficiency without compromising acoustic performance. Measured noise levels remain ≤75 dB(A) at 1 meter-suitable for urban, residential, and noise-sensitive locations.

3. Modular Skid Construction for Rapid Deployment

All components-hydraulic system, compression cylinders, cooling units, PLC cabinet, dispensers, and storage cascade-are pre-assembled on a single detachable skid. Connection pipelines and equipment mounts use quick-release fittings, enabling transport by truck, rail, or barge. Site preparation requires only a level concrete pad and utility connections; commissioning completes within 3-5 days.

4. Easy Maintenance Access & Serviceability

Movable access doors on all sides of the skid enclosure provide full access to compressors, filters, valves, and electrical panels without disassembly. The modular design allows individual component replacement without system shutdown. Integrated explosion-proof lighting and self-ventilation support safe nighttime or indoor maintenance.

5. Explosion-Proof Electrical Systems for Outdoor Safety

All motors, control cabinets, and junction boxes comply with ExdeIIBT3/ExdIIBT4 or ATEX standards. Cables between main motors and explosion-proof boxes route through galvanized steel pipes; other cables use plastic-clad metal hoses for vibration and corrosion resistance. Anti-surge protectors and ESD interfaces ensure coordinated emergency shutdown with station-wide safety systems.
