Portable CNG Fueling Station | MRU-2000 Mobile Refueling Unit

✅ 20ft Container-Integrated Design | ✅ 2,000 Nm³/h High-Throughput | ✅ Oil-Free Hydraulic Compression | ✅ Dual Dispensers + Unloading Post | ✅ ATEX/CE Certified Safety

Our portable CNG fueling station (Model: ZXRY1000-II) is a complete mobile refueling unit (MRU) engineered for rapid deployment in remote locations, fleet operations, and temporary gas supply projects. All critical components-including the DRY1000 hydraulic piston compressor, 1.5m³ CNG storage cascade, dual-hose dispensers, single-hose unloading post, and Siemens PLC control system-are pre-integrated into a waterproof 20ft ISO container (6058×2438×2600mm).

With a designed refilling capacity exceeding 20,000 Nm³/day (based on 10+ hours operation), this portable CNG fueling station accepts trailer-supplied CNG at 30–250 bar inlet pressure and delivers vehicle-grade gas at ≤250 bar. The oil-free lubrication technology ensures zero contamination of compressed gas, while the two-stage hydraulic compression system achieves industry-leading energy efficiency with only 2×45kW motor power. Ideal for mining sites, construction camps, emergency response, and areas without pipeline infrastructure.

1. Fully Integrated 20ft Container Design

All components-compressor, storage cascade, dispensers, unloading post, PLC cabinet, and cooling system-are factory-assembled on a single detachable skid inside a weatherproof 20ft container. 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; full commissioning completes within 3–5 days.

2. Oil-Free Hydraulic Compression & Zero Contamination

The unique DRY1000 compression cylinder design physically separates the gas chamber from the hydraulic oil chamber using multi-stage sealing (Parker/SKF/Simrit). Even in the event of seal degradation, oil cannot enter the gas stream. Post-compression oil content remains close to 0 ppm, eliminating the need for downstream oil-gas separators and protecting dispensers, vehicle pipelines, and engines from carbon buildup.

3. Instant Start Without Depressurization

Unlike traditional mechanical compressors that must vent cylinder pressure before startup to reduce motor torque, our hydraulic drive system isolates motor operation from compression cylinders. The unit starts instantly at full pressure with zero gas waste, reducing compressor cycling by up to 20% and improving daily throughput.

4. Dual-Hose Dispensing + Single-Hose Unloading

Equipped with two JQD-B30B(3MSW) three-line dual-hose dispensers (1–20 Nm³/min flow rate, ±1.0% accuracy) and one CSXQZD11 single-hose unloading post (1–56 kg/min), the MRU supports simultaneous fueling of two vehicles while efficiently transferring gas from tube trailers. The three-line cascade refueling logic maximizes trailer gas utilization, reducing compressor runtime and electricity costs.

5. Fully Automated PLC Control & Remote Monitoring

Siemens CP1H-XA40D PLC with Smart700 touchscreen manages auto-start, pressure sequencing, cascade storage switching, and fault diagnostics. The integrated DRNET remote service platform enables real-time performance tracking, predictive maintenance alerts, and free lifetime software upgrades via TCP/IP or 4G/5G connectivity-reducing manual intervention and downtime.
