1. High Combustion Efficiency

Equipped with high quality and reliable international brand burner, the fuel could burn sufficiently, high combustion efficiency, low harmful gas emission and noiseless operation.

2. Large Diameter Furnace

Adopts horizontal type three pass structure and large diameter corrugated furnace. Large combustion space, the fuel could burn sufficiently. The large radiant heating surface to ensure the high thermal efficiency.

3. Unique Seal of Front and Rear Smoke Box

The smoke box is double door design, open conveniently. It uses multistage labyrinth seal technology, the seal material is special, has good compressibility, no smoke leakage.

4. Multi-function Safety Equipment

Equipped with explosion proof equipment at the back of boiler, prevent deflagration in furnace, discharge high energy, and automatic reset as well, to ensure the boiler operate safety and efficiently.

5. Good Heat Preseration Effect

The boiler shell use aluminium silicate board for heat preservation, the thickness of board is 8cm, high thermal shielding efficiency but low heat loss, to increase the boiler thermal efficiency.

6. Full Automatic Interlock Protection Program

has the protection function of water shortage, over pressure, over temperature, gas leakage, flame out, electric leakage, and phrase-lacking or overloading of motor, etc.,to ensure boiler safe operation.

7. Economizer

Equipped with economizer, make full use of the heat of flue gas, decrease the exhaust smoke temperature, the thermal efficiency could be increased to as high as 98%.
