3.5K 30MM Plastic Resin Coating PTC Positive Temperature Coefficient Thermistor Heater

Aluminum Ceramic Plastic Resin Coating Shell Thermistor PTC Heater For Wax Melting Heater

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

aluminum 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.

Description 

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

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.

Current products

Ceramic shell PTC heating element

PTC heater with temperature controller

Aluminium 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;
