II. Core Product Advantages

1. Large Flow & High Pressure – Regional Gas Supply Hub

• Flow rate: 1320–6700 Nm³/h, supports simultaneous filling of multiple tube trailers.
• Directly connected to high‑pressure city pipeline network for stable, low‑cost gas supply.
• Designed for 24‑hour continuous operation.

• Air-cooled: no water needed, suitable for arid & cold areas.
• Water-cooled: high heat exchange efficiency for long‑time running.
• Dual cooling: strong adaptability to high temperature & humidity.
• Eliminates overheating and water shortage failures.

3. Full‑Process Safety Design

• Triple safety protection:
• Compressor: overtemp, overload, oil‑gas separation.
• Gas circuit: safety valve, emergency shut‑off, breakaway valve.
• Control: gas leakage detection + automatic shutdown.
• Certified with A1 pressure vessel, MOGE, and TS licenses.

• Fully assembled, tested and debugged in factory.
• Installation & commissioning within 7–15 days on site.
• Occupies only 50% space of traditional mother stations.

• SCADA + PLC control: automatic operation, fault diagnosis, remote monitoring.
• Easy online maintenance without shutdown.
• Expandable to LNG‑CNG composite station with dehydration, odorization and storage.

1. High Flow: 1320–6700 Nm³/h for large‑scale filling.
2. Low Energy Consumption: 8%–15% lower than industry average.
3. Ultra Safe: full interlocks and national certifications.
4. Fast Delivery: skid‑mounted for quick commissioning.
5. Local Service: direct factory supply + 7×24h technical support.
