Energy-saving Hopper Dryer SHD-EH

Having over temperature tripping function, it will automatically cut off the power supply to protect the material against blocking when the drying temperature exceeds the set deviation value. The energy-saving heater uses a special made resistance to heat up. When the heating temperature reaches to a critical value, the resistance value will go up rapidly, sometimes even increase by several orders of magnitude. Consequently, the current going through the heater will rapidly decrease, which actually makes the power reduce to make its temperature not go up any more and keep it in a certain temperature to ensure safe operation.
