DT-100M
Membrane separation technology — no condensing equipment required.
Ideal for small gas stations — stable control of tank pressure and exhaust emission concentration.
GreenGuard is Datian’s Stage III vapor-processing unit. It monitors underground storage tank pressure, condenses excess gasoline vapor through cooling and membrane separation, and returns it as liquid fuel — cutting VOC emissions by 95%+ while generating measurable savings.
The latest GreenGuard generation is built for stations that want compliance, lower emissions and a fast payback.
95%+ VOCs reduction: from 1,000–2,500 g/m³ down to <30 g/m³. Helps meet China, EU and Middle East environmental standards.
Typical fuel recovery 0.2–0.4%. Stations often see USD 3,000–20,000/year profit with low energy consumption.
24/7 autonomous operation, 4HP condenser module, optimized oil-gas separation and IoT remote control.
Role-based access, real-time safety alerts, tank-pressure trend tracking, VOCs emission analysis and 2+ years data storage.
Sensors measure underground storage tank pressure in real time. When pressure exceeds the set threshold (recommended 500 Pa / 5 mbar), the unit activates automatically.
The vapor/air mixture passes through an air-cooled heat exchanger and refrigeration unit, then membrane modules. High-concentration vapor returns to the tank; cleaned air is discharged safely.
Recovered liquid drains back into the tank. The cloud dashboard logs every cycle, fuel savings and alarm event — accessible anywhere.

Membrane separation technology — no condensing equipment required.
Ideal for small gas stations — stable control of tank pressure and exhaust emission concentration.
Pressure-auto or pressure & scheduled operation. Monitors tank pressure and starts according to regulation. Compact condensation unit with cloud interface. Ideal for stations with existing Stage I and Stage II systems.
Includes Stage I assist: during tanker unloading, vapor passes through the condensation unit to recover more fuel.
| Model | Stage I assist | Operation modes | Best for |
|---|---|---|---|
| DT-100M | No | Pressure-auto, Pressure & Scheduled | Moderate-temperature regions; pure membrane separation without condensing equipment |
| DT-VR26M1 | No | Pressure-auto, Pressure & Scheduled | Stations with existing Stage I & II systems that need tank pressure control, regulatory compliance and a cloud-connected condensation unit |
| DT-VR26M2 | Yes | Pressure-auto, Pressure & Scheduled + Stage I | Strongly recommended — stations with or without Stage I seeking maximum recovery |
