The heating pipe is a new type heater designed by our company,which shell is not limited by material,you can choose copper,iron,aluminum and ceramic etc according to your requirment.The inner microconductor ceramic heating core(PTC heating core),the resistance will increase while temperature rising until constant temperture current not work longer,needn't addition temperature controller,saving cost and energy,the service life up to 10 years,can refixed,suitable for 12V to 380V,25 to 280℃.

The principle of constant temperature heating PTC thermistor self heating temperature,and then the resistance enter the active zone,the surface temperature of constant temperature PTC heating thermistor will remain constant. The temperature only depend on the Curie temperature of PTC thermistor and applied voltage.  The PTC heater just is heating element which design by the characteristics of constant heating PTC thermistor to heating constantly,in occasion of small or medium power heating,The advantages of is is below:constant heating,no open flame,high heat conversion rate,the supply voltage with minimal impact,long service life and other traditional heating elements incomparable advantages,it is applied more abd more in the electric heating appliance engineer's favor.
