Principle and function of PTC heater:
The PTC ceramic heater produced by the company using patented technology is composed of PTC ceramic heating components and corrugated aluminum strips bonded together at high temperatures. This type of PTC heater has the advantages of low thermal resistance and high heat transfer efficiency, making it an automatic constant temperature and energy-saving electric heater. One of its prominent features is its safety performance. In any application, it will not produce the phenomenon of "redness" on the surface of electric heating tube heaters, which may cause safety hazards such as burns and fires.

PTC heatercharacteristic：
1．Cost saving, long lifespan.
The heating control of the heater can be achieved without the need for specialized temperature sensors such as temperature controllers and thermal resistance thermocouples for temperature feedback. Its temperature regulation relies on its own material properties, thereby enabling the heating of the heater
The product has a much longer service life than other heaters.
2．Safe, green and environmentally friendly.
The design of the heater body has multiple levels of heating temperature below 200 degrees Celsius. Under no circumstances will the body turn red and there is a protective isolation layer. No asbestos or other insulation materials are needed for cooling in any application. It can be used with confidence without causing burns or fires to the human body.
3．save electrical energy.
Comparing electric heating tubes and resistance wire heating products, this product relies on the characteristics of the material itself to adjust its thermal power output according to changes in ambient temperature. Therefore, it can optimize and control the energy consumption of the heater to the minimum, and the high heating efficiency material also greatly improves the utilization efficiency of electrical energy.

·Rapid temperature rise, able to control temperature even in case of fan failure, long service life
·Wide voltage range, can be designed between 12V-380V as needed
·Easy to design, can be designed from low power to high power, and the appearance can also be designed according to requirements
·Non combustible, safe and reliable, PTC does not turn red or open flames when heated
In small and medium power heating scenarios, PTC heaters have advantages that traditional heating components cannot match, such as constant temperature heating, no open flame, high heat conversion rate, minimal influence from power supply voltage, and long natural life. Their application in electric heating appliances is increasingly favored by research and development engineers.

Precautions for use
(1) PTC heating elements have the characteristic of automatic constant temperature, and do not require a temperature control system. Simply power on the PTC heating element.
(2) When PTC heating elements are used to heat liquids (such as water), The PTC heating element will not be damaged.
(3) If PTC heating elements are used to heat cold air without air supply, The PTC heating element will not be damaged.
(4) Long service life, used in normal environments, with a lifespan of over 10 years.
(5) Reliable operation, utilizing the internal characteristics of PTC heating elements for temperature control, never exceeding the temperature limit.
(7) The working voltage is very wide: when the working voltage changes by 2 times, the change in surface temperature is very small.
(8) When multiple PTC heating elements are used together, they should be connected in parallel and not in series.
(9) Different heat dissipation conditions result in significant differences in the heating power of PTC heating elements.
(10) The heating power decreases from high to low after being powered on, and finally stabilizes. The stable power is related to the usage conditions. For the same PTC heater, the power may differ by several times depending on the usage conditions. The faster the heat dissipation, the greater the stable power; The higher the surface temperature of PTC, the higher the power.
(11) The surface temperature of PTC heating elements is controlled by PTC itself or by disconnecting the circuit, but cannot be controlled by adjusting the voltage.
(12) PTC itself has high reliability and long lifespan, but if assembled improperly, the product may experience unstable power and temperature.
(13) When multiple PTCs are used together, they should be connected in parallel and not in series.
