Temperature control: The system temperature fluctuation can be controlled within ± 1 ° C, meeting the requirements of rigorous processes such as semiconductor material synthesis and polymer reactions;

Multi fuel adaptation: flexible and compatible with clean energy sources such as natural gas, diesel, and biofuels;

Energy efficiency leap: Integrated heat exchange and low nitrogen combustion technology, comprehensive thermal efficiency exceeds 90%;

Low carbon gene: The carbon emissions per unit of production capacity are reduced by 20% -30% compared to traditional boilers, and the nitrogen oxide emissions are better than the national standard limits.
