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.
