Box-type multi-purpose furnace

The box - type design of the furnace is a key factor in its superior performance. It provides excellent heat retention, reducing heat loss during operation and significantly enhancing energy efficiency. By minimizing heat dissipation, the furnace can maintain the desired temperature more effectively, resulting in lower energy consumption and reduced operational costs. Moreover, the enclosed structure of the box - type furnace acts as a barrier, protecting the internal components from external co...
