Features: high quality refractory insulation materials, high temperature belt with imported nano insulation materials, good thermal insulation effect. Wide break and free from burning, can automatically adjust the air-fuel ratio to achieve the best combustion effect (oxidation and reduction can be achieved). Full automatic control by microcomputer, adopting the high efficient heat exchangers, combustion-supporting wind temperature of 300 ° C, low energy consumption, than the similar furnace energy saving 20% 30%.
