380V 1.5KW explosion proof immersion heater

Short Description:

An Immersion heater is used to heat liquids, oils, or other viscous fluids directly. Immersion heaters are installed into the tank holding a liquid. Since the heater comes in direct contact with the fluid, they are an efficient method of heating liquids. Immersion heaters can be installed through a variety of options in a heating tank.
