Hotohms™PTC ceramic heater device for electirc heating furnace
The heater device adopts the ceramic PTC heaters as the heating material and uses the semiconductor hole principle to convert the electric energy into heat energy.
The ptc heater  through the liquid flow will increase the temperature and the heat of the PTC heater, PTC standard parts installed in a special alloy tube, the heat transfer to the container through a special alloy tube liquid, with a safe and reliable, water separation, the PTC, that is, long life, energy saving and environmental protection, etc., mainly used in household and industrial water heaters, other liquid heaters, auxiliary heating and other heating equipment.

Fast heating rate：2～3s  out of hot water  ，long working life

Characteristic :
-Separation of water and electricity: PTC heating plate on the outer wall of the heating water tank, realize the separation of water and electricity.
-High thermal efficiency: for heater heat transfer surface water with large contact area, so not on the contact surface of the produced water bubble (bubble water isolating heat conduction), so the thermal efficiency than that of electric heating tube is much higher; PTC heating elements in heating only generate heat, no light consumption; and heating wire in the heating pipe in addition to generate heat, but also light produces light consumption.
-Power self regulating: heater power changes with the change of the temperature of the water heater tank, if there is no water in the water tank,the heater to reach a certain temperature thermostat keeps the temperature. At this time, the basic no working current, basically there is no power.
