Principle and function of PTC electric heater

Features of PTC ceramic heaters
1. PTC ceramic heaters are cost-saving and have a long life.
The heater can be heated without special temperature controllers and temperature sensors such as thermal resistors and thermocouples for temperature feedback. Its temperature regulation depends on its own material properties, which makes the product have a much longer service life than other heaters.
2. PTC ceramic heaters are safe and environmentally friendly.
The heater body is designed to have multiple levels of heating temperature below 200 degrees Celsius. The body does not turn red under any circumstances and has a protective isolation layer. In any application, asbestos and other insulation materials are not required for cooling. It can be used with confidence without the problem of scalding the human body or causing fire.
3. PTC ceramic heaters save electricity.
Comparing electric heating tubes and resistance wire heating products, this product relies on the characteristics of the material itself to adjust its own thermal power output according to the change of ambient temperature, so it can optimize the electric energy consumption of the heater to a minimum, and at the same time, the material with high heating efficiency also greatly improves the utilization efficiency of electric energy.
·Rapid heating, automatic temperature control even when fan fails, long service life
·Wide voltage range, can be designed between 12V-380V according to needs
·Easy to design, can be designed from low power to high power, and the appearance can also be designed according to requirements
·Non-flammable, safe and reliable, PTC does not turn red when heating, no open flame

In small and medium power heating occasions, PTC heaters have the advantages of constant temperature heating, no open flame, high heat conversion rate, minimal influence of power supply voltage, and long natural life, which are the advantages of traditional heating components. Their application in electric heating appliances is increasingly favored by R&D engineers.

Notes on the use of PTC ceramic heaters
(1) PTC ceramic heaters have the characteristics of automatic constant temperature, no temperature control system is required, and the PTC ceramic heater can be directly powered on.
(2) When the PTC ceramic heater is used to heat liquid (such as water), the PTC ceramic heater will not be damaged after the liquid is dried up.
(3) If the PTC ceramic heater is used to heat cold air, the PTC ceramic heater will not be damaged when no air is supplied.
(4) Long service life. When used under normal conditions, the service life can reach more than 10 years.
(5) Reliable operation. The temperature is controlled by the internal characteristics of the PTC ceramic heater, and it will never overheat.
(6) The working voltage is very wide: when the working voltage changes by 2 times, the change in surface temperature is very small.
(7) When multiple PTC ceramic heaters are used together, they should be connected in parallel and not in series.
