Fibreglass Hopper Heater

Hopper Surface Heating Systems keep temperatures over the dew points for moisture and acids. For ESP Hoppers, Bag House Hoppers, Material & Dust Collector Hoppers, and Fiberglass Cloth Hopper Heaters, we develop and manufacture these heaters. It provides even heat transfer over the surface, preventing any hot spots or carbonization of the substance. It is simple to manage and has a consistent temperature. The elements loosely follow the vessel surface temperature and are made to operate in the black-heat area.

The electrical Fiberglass Hopper heating pad is made up of highly resistivity of wire heating components and are insulated by two braids of glass-fiber yarn/ PTFE/PFA/FEP these type of fluoropolymer. The element is once more sandwiched between two layers of tightly woven glass cloth and distributed out over the carrier at a consistent pitch. The heating element is connected to power supply through fiberglass insulated and silicon rubber sheathed cable. Series /parallel type of circuit are used in heating element design.
