Unlike traditional heating elements that use a resistance wire such as Nichrome to generate heat, PTC heater is made of PTC ceramic heating element and aluminum tube. It is an automatic constant temperature heater and does not need any additional temperature applications.it is a new kind heater in the market .It is fixed by a pair of metal electrodes with leads on both sides of PTC element.
PTC heater is widely used in:
Hot milk device coffee heater
Water heater the physiotherapy device
Warm foot device extruding machine
fan heater heat preservation cup
physical therapy apparatus
The main advantage :
1.High effective,
2.protects rank high
3.It can control the temperature by itself
4.Used in large range of voltage from 12V to 240V
5.leaks electric current small,life long and do not generate RFI noise.
6. It doesn't turn to red or get fire when it is working.
7.Even with the regard to voltage changes, the constant temperature mechanism will be effective.
