Explosion — proof heaters are heating installations that externally represent a metal block, inside which heating elements and an electric motor with a fan impeller are located. Explosion-proof terminal boxes, equipment for connecting power supply and controlling the heater are located outside the housing.

The installed fan allows you to control the direction of the heated air, increase heat exchange from the surface of the heating elements and ensure uniformity of the air temperature inside the room.

They are used for heating industrial premises, warehouses, and mobile buildings where explosive gas mixtures may occur during operation.

Explosion-proof heaters can operate in explosive zones 1 and 2 of categories IIA, IIB and IIC with temperature class T2…T6. Explosion protection is provided by the use of explosion – proof components and terminal boxes with a degree of explosion protection-Exd explosion-proof shell, which does not allow the explosion to spread beyond the shell into the atmosphere.

Depending on the characteristics of the environment, the temperature class of heaters is selected – the maximum permissible temperature of the heating elements and the temperature of other parts of the equipment in contact with an explosive environment.

To prevent overheating of the heating elements above the permissible temperature, the heating group is equipped with surface temperature monitoring sensors.
