What Is ‘Ex D’ Protection Type for Flame Proof Motors
The presence of explosive atmospheres is very common in processing industries. Therefore, such industries having explosion-oriented environments need special precautions for choosing motors. The motors designed under ‘Ex D’ category provide an optimal protection solution for the industries having possibility of explosion because of the presence of gases, chemicals, fumes, etc in the environment. The prime objective of an Ex d class motor enclosure is preventing an internal explosion from spreading out. The Group D hazardous areas are subjected to the presence of gases like benzene, butane, acetone, ammonia, ethanol, gasoline, natural gas, naphtha, propane, etc. The ‘Ex D’ protection stops flame and sparks.
