Convecting type: moistureproof and dew proof for electronic equipments, heating for electronic controll case, room heater.

3. Notice in appliance. 

Blowing type:

1)This type of PTC air heater need a fan to blow, usually the faster is the air blowing speed, the larger is the power;

2)When PTC is used in very low ambient temperature, it have to be special designed;

3)PTC heater do not be damaged without air blowing, but the power is very low;

4)The power could be adjusted by air blowing speed; or it could be adjusted by voltage; or changing the number of heaters.

5)The surface tempetature on heater would be higher without air blowing. A thermostat could be assembled on the heater, preventing the damage of the holde;

6)The surface temperature on dispersion plate is closed to the curie temperature, without air blowing; but the surface temperature on dispersion plate will be lower than the curie temperature very much, with air blowing;

Convecting type.

1)Heating power depends on assembling methods, direction of the heater;

2)Keep air flowing itself for heat could be diffused;

3)The heating power will be increased 2~4 times, when the heater is blowed;

4)The heating power will be increased, when the heater is assembled on a metal holder.

4. Current products.

Blowing type.

Uninsulated air heater.1) Customer’s required power and dimensions was possible; the larger is the area of radiator, the larger is the heating power;

2) 6~400V of rated voltage, DC or AC, are possible;

3) UL file for PTC pellet: E207611;

4) 80~250°C of switch temperature is posible; the power is direct radio with temperature difference (ΔT = switch temperature-ambient temperature).

Uninsulated air heater with low windage resistance.1) Customer’s required power and dimensions was possible; the larger is the area of radiator, the larger is the heating power;

2) 6~400V of rated voltage, DC or AC, are possible;

3) UL file for PTC pellet: E207611;

4) 80~250°C of switch temperature is posible; the power is direct radio with temperature difference (ΔT = switch temperature-ambient temperature).
