Integrative combustion configuration system
This series boiler adopts horizontal internal-combustion, and three-pass full wet-back structure, and also adopts advanced threaded flue heat transfer technology. The front and rear smoke boxes are equipped with removable doors. The product is consisted of chassis, shell, thermal insulation layer, burner, electric cabinet and corresponding water and electricity lines. Heavy oil, light oil, natural gas and urban gas are all suitable for this product. And it can meet heating and air conditioning and production needs of many buildings.

Advanced full-automatic control function
Adopt the full-automatic microcomputer program control, and intelligent control of integrated automatic pressure control, flame detection, water deficiency protection, automatic alarming, etc. The intelligent one-key control brings easy operation, and you need only to press the key gently, and then the boiler will enter the full-automatic operation state, and all safety protection devices will start to work without person on duty, making the operators feel more secured and assured.

Safe and scientific structural design
It is equipped with multiple interlock protection devices such as safety valve, pressure controller, water level controlling protector, etc., ensuring absolute safety and reliability. Adopt the rectangular fin tube and tubular furnace structure which can compensate the thermal expansion effectively, prevent thermal stress, make the boiler structure be safe and reliable, and lengthen the service life of the boiler.

High-quality and fast steam
The unique design of small water volume and large steam kiln bring fast steam generation within shortest time, and the built-in steam-water separating device guarantees top-quality steam of high dryness.
