1. Product Description

PTC components are glued with wave aluminum tube by heating. It highlights in small thermal resistance, fast warming-up and long life length. MZFR series can be applied to window air conditioner, bathroom warmer, washing machine, sterilizer, heating apparatus and vehicle devices.
Usually we provide customized solutions.

Rated frequency (Hz): 50(60Hz)
Range of length (mm): 80~500
Power range (W): 500~3000
Tolerance of power (%): +5~-10
Max initial current (A): ≤ 1.5 Ie
Withstand voltage (V): 450
Power decay rate (%): ≤ 10%/1000h
Max surface temperature (degree): 270.




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.

Uninsulated air heater with low windage resistance.

Notice:

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 ratio with temperature difference (?T = switch temperature-ambient temperature).
