Three Layers Coil Tubes + 3-Pass Design

Effectively use the high temperature, smoke stay inside boiler to heat thermal oil 3 times, greatly reduce temperature of outlet  smoke, improve boiler thermal efficiency, energy saving, reduce fuel cost


Oil Cover Fire Structure + Wet Back Type

1. Pipline oil surround the fire, endothermic sufficient, heating up fast and evenly 2. Smoke transfer room is wet back structure, avoid burning deformation, ensure boiler lifespan


Double Layer 12cm Aluminum Silicate Insulation

We use double layer 12cm aluminum silicate insulation cotton, boiler surface temperature is not higher than 40 ℃, energy saving and high efficiency


Intelligent Monitoring, 100% Safe Running

PLC control, automatic data collection analysis system, over oil temperature/over smoke temperature/low flow alarm, easy for operate and make sure the safe
