Features of PTC heating element 

 High Reliability and Security. The temperature of PTC heating element will rise when wind speed is zero. Due to self-limiting of PTC, temperature rise can control between 100-300 ℃。When use nichrome as heating element, the temperature will reach 700-800 and may catch fire easily.



◪ Calorific Value can be adjusted easily. The heating power of PTC can be adjusted by the dissipation coefficient, such as change the product appearance structure, wind speed, air delivery and so on.



◪ Low requirement on stability of power supply. PTC has the characteristic of hyperbola on the volt-ampere characteristic curve, it can make the power basically stable when the voltage fluctuates. When nichrome is used as heating element, the heating power is proportional to the square of voltage. So when the power supply voltage changes, it has a great influence on the heating power.

 



◪  Calorific value can be adjusted automatically with the change of ambient temperature. That is, energy saving and environmental protection. When the ambient temperature increases, the heating power of PTC will decrease, and vice versa. This not only saves energy, but also keeps wind temperatures stable.

 



◪  High thermal efficiency; Thermal efficiency can reach 92% commonly, individual structure can achieve 99% above.

 



◪ Durable with non-oxidation and high service life. Continuous work on and off 100,000 times, the aging rate shall not be more than 50%.Continuous dry burning for 1000hours,the aging rate is not more than 10%.
