PTC heaters for refrigerator is one product of PTC heater base PTC. The resistance, voltage and the pow are customized. We can make many kinds of PTC ceramic heaters, as customers' request.
PTC (Positive Temperature Coefficient) is the acronym means that the temperature coefficient is, the great pan-corrected temperature coefficient of semiconductor materials or components.
Advantage as follow:
1. It is safety.
2. It has high power.
3. It has high reliability.
4. It doesn't turn to red or get fire when it is working.
5. It uses wide range of ambient temperature.
6. It can be manufactured to have different fixed temperatures at which the dramatic resistance change take place..
7.Even with the regard to voltage changes, the constant temperature mechanism will be effective.
8. It can be an effective low cost solution.
9.It has a virtually unlimited service life, and do not generate RFI noise.
10 Dynamic heating output and self-regulating function in correlation to the ambient temperature.
Special:
Unlike traditional heating elements that use a resistance wire such as Nichrome to generate heat,PTC heating elements are made as ceramic stones, ase on barium titanate. They have unique characteristics as semeconductors and their ferro-electric propertise can be precisely determined during their design.
