PTC Heater

Introduction

PTC (Positive Temperature Coefficient) heater is a smart heating element that utilizes the property of PTC ceramic materials — resistance rises sharply when temperature increases. This unique characteristic enables automatic constant temperature control without the need for additional controllers.

Core definition

A PTC (Positive Temperature Coefficient) heater is an electric heating element made by taking advantage of the characteristic of PTC ceramic material that "resistance increases sharply when temperature rises".

Core advantages

Constant temperature: After the temperature reaches the set value, the resistance increases sharply and the power drops sharply. It can automatically control the temperature without an additional temperature controller, avoiding overheating.

• Safety: No open flame, controllable surface temperature, reducing the risk of fire and scalding.

• Energy efficiency: Fast heating rate, high heat conversion efficiency, and low power consumption during the constant temperature stage.

Main application scenarios

• Household appliances: air-assisted heating, electric heaters, humidifiers, dryers, etc.

• Automobiles: On-board air conditioning heating, battery pack insulation (commonly used in new energy vehicles).

• Industrial/Commercial: constant temperature heating for equipment, heating for small Spaces, etc.
