Blowing air heater

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）Please tell us, if PTC heater is intended to use in very low ambient temperature, or in very strong air blowing. 3）PTC heater does not be damaged without air blowing, but the power is very low. 4）The power could be adjusted by air blowing speed, applied voltage, or the number of heaters. 5）The surface temperature on heater without blowing would be very higher than with blowing. A thermostat could be assembled on the heater, preventing the damage of the holder. 6）The outlet air temperature depends on surface temperature on heater, intake air temperature air speed. Normally outlet air temperature is between 80~110℃; Other outlet air temperature could be special made. 7）The radiator of non-insulated PTC air heater is electriferous. 8）Higher is the surface temperature of PTC, the larger is the power; but the reliable, and life time are worse.

Notice:

 1) Customer’s required power, and dimensions, outlet air temperature were possible, the thickness can be 15mm, 20mm, 24mm, 30mm; for larger area of radiator, thicker, more PTC ceramic, larger air speed, lower inlet air temperature, the heating power would be larger; 2) 6~600V of rated voltage, DC or AC, are possible; 3) UL file for PTC pellet is E207611; 4) 80~250℃ of switch temperature is possible; the power is proportional to temperature difference (ΔT = switch temperature－inlet air temperature). 5) This type of heater is with low wind drag, and low noise, but the power density is lower.
