The hand dryer without heating device is suitable for the temperature requirements of the more demanding places, common hand dryer use frequently, such as: frozen vegetables, quick vegetables, hand dryer, hand dryer, hand dryer, hand dryer, hand dryer, hand dryer. For example: frozen vegetables, frozen dumplings packaging workshop.

2、PTC heating

PTC thermistor heating will be with the ambient temperature changes, PTC heating power also changes, winter time PTC heating power
PTC is characterised by good temperature constancy, but also has a certain disadvantage. PTC is characterised by good temperature constancy, but also has a certain disadvantage, no electric heating wire temperature up quickly.

3、Heating by electric wire

The traditional electric heating wire, the wind temperature rises quickly, but the wind temperature constancy is poor, easy to wind temperature is high, the hands have burns. High-speed hand dryer. The use of electric heating wire plus CPU with temperature sensor control *, to achieve the effect of fast and constant wind temperature rise, even if the wind speed up to The hand dryer is able to blow a constant warm air even when the wind speed is up to 100 m/s. Generally speaking, the noise level of air-based and heating-based hand dryers is relatively high, while the noise level of heating-based hot air hand dryers is low.
