HEATERS WITH FLAME PROOF ENCLOSURES
Flame-proof heaters are designed in such a way that they could be operated in hazardous environments where there is a risk of explosion. These are constructed to contain any potential ignition source within the heater’s enclosure, preventing it from igniting flammable gases or vapours in the surrounding atmosphere. So, a flameproof heater is a type of heating element that is designed to withstand high temperatures and is used in industrial processes. It is typically encased in a metal or ceramic enclosure and is connected to an electric power source. It is resistant to explosions and is used widely in hazardous environments.
