Explosion-Proof Heaters (ATEX certified) provide neutral convection solutions of heating for electrical equipments in hazardous industrial locations where potential for explosion exists due to the presence of flammable gases, vapors, powder-metals or dusts.
Explosion-Proof Heaters are also designed to eliminate the moisture in enclosures or designated spaces. Moisture, especially when combined with aggressive gasses and dust, causes atmospheric corrosion and can result to failure of components such as circuit breakers, busbars, relays, integrated circuit boards, transformers and so on.
Failure of components is generally caused by changing resistances, flashovers, creepage currents or reduced insulation properties. Moisture and corrosion will remain at low level if air humidity does not exceed 60%. To eliminate moisture in an enclosure, the temperature inside the enclosure must be approximately 5°C higher than the outside temperature. Ex-proof heaters provide constant temperature for optimal operating condition at hazardous enviroments.
