A cubical furnace has two parts, one is nonmoving shell with combustion system, the other part is used to load, carry, and unload the material to be heated. A furnace used for all other standard applications as mentioned. It also can be used in the applications of specialized treatment processes. Advantages: our furnaces are designed in such a way to reduce the fuel consumption. Combustion/ heating equipments are designed with the thermal equations. Our heating systems will be positioned in order to better heat transfer rate through circulation and re-circulation. Our furnaces are designed for skin temperature of 65?c (maximum) Lining: refractory and insulation bricks and ceramic fiber blankets based on the temperature and operation of the furnace. As per the ISO standard packing.
