Our washdown and explosion-proof heaters are ideal for applications that involve hazardous materials or equipment that needs to be washed or hosed often. Washdown heaters are great for dirty/dusty environments where the ability to easily clean the heater is critical. Simply spray the heater down and it will remain long lasting. Explosion-proof heaters are ideal for hazardous environments where the presence of flammable gases, vapors, or dusts exist. These explosion-proof heaters operate with surface temps below the ignition temperature of the hazardous environment and are housed in appropriate enclosures.
