PTC Thermistors (thermal resistor), also called PTC stone, are ideal heating elements. Thanks to self-regulation properties, heating devices based on PTC thermistor technology can generally dispense with control and regulating components as well as with over-temperature protection, PTC thermistor heating elements are used wherever measurement and regulating equipment as well as heating devices must be housed in tight confines. PTC Heating elements can be designed to be square, rectangular, round, ring or doughnut form, or housed in aluminum, stainless steel, silicon casing.
PTC Heater Features:
Safe through temperature limiting characteristics.
No danger of fires since there are no glowing parts.
Dynamic, self regulating, and therefore energy efficient.
No excess temperature protection required.
Voltages from 6V to 480 V; Special voltage applications up to 800 V.
PTC surface temperatures can be set from 50C to 320C.
Compact design.
Long service life.
