II. Core Product Advantages

1. Hydraulic‑assisted Unloading · Near 100% Gas Utilization

• Hydraulic cylinder tilts the tube bundle to fully empty residual gas.
• Unloading speed more than 2x higher than conventional stations.
• Mechanical lock + pressure interlock ensures safe tilting and retraction.

• Works directly with CNG tube trailers – ideal for suburbs, counties, industrial zones.
• Prefabricated skid design: commissioning within 72 hours.
• 60% lower investment than traditional CNG stations.

3. Full‑process Safety Protection

• Multi‑level interlock: emergency shut‑off, breakaway valve, safety relief, leak detection.
• High‑precision regulation (AC1) and metering (error ≤ ±1.5%).
• Anti‑corrosion & weather‑resistant design for 20+ years outdoor service.

• PLC + SCADA for automatic unloading, pressure control, statistics, alarm.
• IC card / mobile payment supported; unattended operation available.
• Modular layout for online maintenance without shutdown.

5. Flexible Adaptation · Wide Application

• Customizable flow and dispenser quantity for small to large stations.
• Upgradable to LNG‑CNG composite station or emergency supply station.
• Movable skids and flexible tube trailers support mobile gas supply.
