PTC heater with shell

1. Configuration.






Aluminium shell

Aluminium shell, with   wire and insulating film

Fast heat conduct, large power

The shell iselectric conductor, may affect the circuit; it’s can not be very small in bulk

Suitable for liquid heating, air heating, heating a surface


Ceramic shell, with wire and ceramic insulation

Low cost, small bulk, insulating shell

Not suitable for large power, easy to crack

Suitable for very small bulk, low power

Plastic   shell

Plastic shell, with wire and plastic insulation

Low cost, small bulk, insulating shell

Not suitable for large power, and high temperature

Suitable for very small bulk, it can insert on a circuit board

Resin   coating shell

Resin coating, with wire, resin insulation

Low cost,small bulk, insulating shell

Very small power, bad heat conduction, low temperature only

Suitable for very small bulk, it can insert on a circuit board

Heater with temperature controller

With atemperature controller to control the temperature of heating object

the temperature of heating objectcan can be ±2℃ of accuracy

High cost, large bulk, more complex structure

Suitable forcontrolling the temperature in a small range

Other configurations are shown in the picture of “Various kinds of aluminum shells”

2. Some samples of uses. 

1) Aluminum shell. It is very easy to fit, constant temperature, safty, long last time. PTC heater is very appropriate under 260℃ temperature. Main appliances: hair straightener, hair curler (crimper), wax melting heater, humidifier, water boiler, liquid warmer, coffee warmer, polymer press-coating heater, hot glue gun, chocolate extruder. For detailed uses of PTC, air heater, hair straightener, hair curler, drink warmer, water heater, vapor generater, read other pages in this website.

2) Ceramic shell. It is very appropriate for low power amd 50~250℃, Main appliances: mosquito destroyer, aroma emanater, massager, hair straightener.

3) Hair straightener plate. There are several materials to be choosed, such as aluminum plate coated with ceramic paint, aluminum plate oxygenated, aluminum plate coated with teflon, aluminum plate electroplated, ceramic plate polished, ceramic plate glaze coated. Many color can be choosed. For details of hair straightener, read another page in this website.

3. Notice in appliance.

1) After switching on, the initial heating power is large, and then decrease, finally it become steady state. The steady state power depends on appliance conditions. Faster is the heat conduction, higher is the steady state power; higher is the surface temperature, higher is the steady state power.

2) The surface temperature of PTC can be controlled by itself, control circuit and protecting circuit may be omitted in most appliances.

3) It can be used for heating liquid, and it’s no problem when liquid was dried.

4) Very high reliable, over temperature was impossible. 

5) The surface temperature increases (or decreases) about 8℃, when supplied voltage increases (or decreases) 2 time.

6) Our PTC products are reliable, long aging, but if they are assembled improperly, the end product may be loose, power or temperature may be instable. 

7) Parallel connection is necessary for two or more PTC connection. 

Heater with temperature controller

Alumniunm shell, ceramic shell heating element could be controlled by a temperature controller. One type is temperature control type, needed temperature can be set by customer and controlled itself. Another type is voltage adjusting type, the applied voltage can be adjusted lower or higher, and then the temperature will be lower or higher.


a) Surface temperature can be selected between 50℃~280℃. Rate voltage can be 220~240VAC; 

b) UL file of PTC ceramic: E207611.
