High efficiency and energy saving: Utilizing highly efficient Korean vacuum hot-water boiler technology, steam heating(condensing for heating) effectively improves heat efficiency with good ability to exchange heat and tri-circulation design, the rear smoke path installs surplus heat recycle equipment to increase resource usage rate. the heat usage rate is as high as 96%.
The Unit operates in a vacuum, the heat media is under vacuum conditions with no danger of expansion or explosion. The boiler also stores constant heat-media water without danger of burning out, there are many self-protection installations with un-matchable safety features by other boilers.
Send InquiryNo rusting, no accumulation to prolong useful life.
The heat exchange machines use stainless steel material for the heat media to operate under closed space. under high temperature, there is no rusting, no furring to prolong the life of the boiler, almost twice as the normal boilers, making it almost 20years.
Abundant models, various usage for one machine, Horizontal and vertical, fuel oil, gas, water, smokestacks variety of furnace type are available free choice。 heat exchange and the header separation, heating water, hor water shunt supply, to meet the users use of the heating water and clean hot water different requirements to ensure that hot water cleaning and stability.
Small volume, easy for installation: module design, high-quality heat exchange components, and the unit bulk are small, all these made transportation and installation easy, in a small space, many units can be used together.
Extraordinary environmentally friendly function: high electrical heating pipe to significantly prolong life.
Elimination of complicated inspection procedures, the unit operates under vacuum conditions, eliminating the reporting for inspection for pressured vessels. there is no annual inspection needed, and no special permit is needed for operation.
Intelligent control: touch screen display, simulated buttons, with Chinese and pictured display operating conditions, eliminating the reporting for inspection for pressured vessels. there is no annual inspection needed, and no special permit is needed for operation.
