Description
1. Configuration.
| Type | Specialty | Excellence | shortcoming | Others |
| Aluminium shell | Aluminium shell, with wire and insulating film | Fast heat conduct, large power | The shell is electric 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 | 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 a temperature 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 for controlling 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, safety, 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. Other aluminium shell heater, such as water heater, diesel heater, air heater, hair straightener, hair crimper, see other page in this website.
2) Ceramic shell. It is very appropriate for low power and 50~250℃, Main appliances: mosquito destroyer, aroma emanater, massager, hair straightener.
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) The surface temperature increases (or decreases) about 8℃, when supplied voltage increases (or decreases) 2 time.
4) 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.
5) Parallel connection is necessary for two or more PTC connection.

PTC 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.
Notice:
1) Surface temperature can be selected between 50℃~280℃. Rate voltage is 220VAC;
2) UL file of PTC ceramic: E207611.
