Explosion-proof electric heater guide

The heaters are explosion-proof heaters designed and manufactured according to standard components . They are used in hazardous environments and have the following explosion-proof certificates.

To select the right heater, you need to know the following questions :

Conduction: Conductive heaters use less energy than convection heaters with heat sinks. Heat transfer through metal is much more efficient than through air. Because the air inside the incubator surrounds the measuring instrument, air is a good thermal insulator. In order to facilitate heat transfer, the surface of the conductive heater is flat, and therefore it is required that the heated device part also has a flat surface for mounting the fixed heater.

Convection: The air in the protection box acts as a heat transfer medium from the heater to the heated instrument.

Advantages : Renke shaped devices ( regular or irregular ) can be heated.

Disadvantages : The protection box must be fully insulated so that the heat loss is reduced. The primary factor is the seal of the protective box.

Heat Loss Calculation Formula Maid Under IN Protection of ERTEC Protection Box ): Household = Thermal Conductivity x 1m Degree Difference = K' delta Th

When calculating the required heating power, the K value has retained a safety factor of 20 % . As much as possible is not suitable for explosion-proof heaters. A thermostat must be used to control the electric heater to prevent the heater from getting too hot and close to the melting temperature.
