Product Description

Ultra-low Nitrogen Condensing Vacuum Hot Water Boiler
Our technology adopts the revolutionary planar combustion ultra-low nitrogen tube bundle water-cooled furnace body. The planar combustion is composed of tens of thousands of flames, combined with the unique tube bundle type furnace body structure, allowing the flames to cool rapidly. This inhibits the generation of nitrogen oxides, reducing emissions to below 30mg/m3. The boiler can produce hot water within 5 minutes of startup, reducing heat loss during cleaning by 20%. Operating efficiency reaches as high as 104%, achieving low noise and high efficiency.
