It delivers better performance, more reliable regulation, and uniform temperatures than other comparable heating technologies on the market today.PTC materials are known for their high thermal stability, meaning they can maintain a consistent temperature even when subjected to variations in input power. PTC technology uses electricity to convert heat into infrared energy. Heating materials are known for their high efficiency and safety, making them a popular choice for space heaters.

What is a PTC Ceramic Heater?

Ceramic heaters are electric heaters that utilize a positive temperature coefficient (PTC) ceramic heating element and generate heat through the principle of resistive heating. Ceramic materials possess sufficient electrical resistance and thermal conductivity to generate and conduct heat as current flows through them. They have high strength and durability. Hence, they perform well when used as a heating element. The heating element of ceramic heaters are made of pure ceramic material, but most are composite materials that consist of the encapsulation of metal and ceramic materials. The ceramic material in the latter acts as an insulator but conducts heat to the surroundings simultaneously, which minimizes the heat and energy losses associated with uninsulated resistance wire.

Ceramic heaters are used in a wide range of industrial processes such as drying, boiling, molding, and melting products. They are widely utilized in space heating. They provide a quick, safe, and clean source of heat.

Heating principle of PTC Ceramic Heater

PTC ceramic material is semi-conductive and when voltage is applied to it, the power decreases quickly as it reaches a certain temperature according to the particular composition of the ceramic. The ceramic elements are in contact with aluminium fins, thereby heating the fins. A fan blows air across the fins, cooling the fins as they heat the air.

PTC Ceramic Heater Types:

The constant temperature heating PTC thermistor can be made into a variety of shapes and structures and different specifications, the common ones are wafer shape, rectangle, strip shape, ring and honeycomb porous shape, etc. The combination of the above PTC heating elements and metal components can be formed Various forms of high-power PTC heating elements.

PTC heating elements are divided by conduction method

(1) PTC ceramic heating element based on heat conduction. It is characterized by an electrode plate (electrical conductivity and heat transfer) and an insulating layer (electrical insulation and heat transfer) that are mounted on the surface of the PTC heating element. Thermal conductive glue) and other multi-layer heat transfer structures, which transfer the heat emitted by the PTC element to the heated object.

(2) Various PTC ceramic hot air heaters that use the formed hot air to conduct convective heat transfer. It is characterized by large output power, and can automatically adjust the blowing air temperature and output heat.

(3) Infrared radiation heating element. Its characteristics actually use the heat quickly emitted from the surface of the PTC element or the heat-conducting plate to directly or indirectly stimulate the far-infrared paint or far-infrared material that touches its surface to radiate infrared rays, which constitutes the PTC ceramic infrared Radiant heating element.

PTC heating elements are divided according to structural characteristics

(1) Ordinary and practical PTC ceramic heating elements. Such appliances mainly include: electric mosquito repellent, hand warmer, dryer, electric heating plate, electric iron, electric soldering iron, electric heating adhesive, curling iron, etc. Its characteristic is that the power is not large, but the thermal efficiency is high and it is practical.

(2) Automatic constant temperature type PTC heating element. This kind of appliances mainly include: small crystal device constant temperature bath, constant temperature incubator, electronic thermos bottle, incubator, thermos cup, insulation tray, insulation cabinet, insulation table, etc. It is characterized by automatic heat preservation, simple structure, good constant temperature characteristics, high thermal efficiency, and wide operating environment temperature range.

(3) Hot air PTC heating elements. This type of hot air PTC heating elements mainly include: small warm air heaters, hair dryers, heating machines, dryers, drying wardrobes, clothes dryers, industrial drying equipment, etc. Its characteristic is output The hot air has high power, rapid heating, safety, and can automatically adjust the air temperature and power consumption.

Advantages of Ceramic Heaters

• Ceramic heaters are powered by electricity, thus providing a clean source of heat. Fuel-powered heaters generate smoke and toxic gases as a by-product of combustion, which is harmful to the environment and health when released. Hence, gas treatment and ventilation are required. The price of fuels such as propane, gasoline, diesel, and kerosene is also increasing.

• Ceramic heaters are easy to operate. They can start heating spaces and objects right after they have been plugged and switched on. With the appropriate rating and specifications, ceramic heaters can quickly and effectively warm spaces and objects.

• Ceramic heaters are safe. Unlike fuel-powered heaters, which involve combustion, there are fewer risks of fires when electric heaters are used. Since ceramic insulators are used, there is a low possibility of creating sparks that can ignite flammable materials. However, the safety protocols in operating electrical appliances must be observed. One must keep a distance from the glowing heating element of the ceramic heater.

• Ceramic heaters can conveniently and flexibly warm spaces and objects. They can be installed in industrial equipment to heat materials and products.

• Ceramic heaters are compact. They can produce a lot of heat despite their size. Space heaters can be placed in tabletops, floors, shelves, and walls.

• Ceramic heaters can be equipped with thermostats, thermocouples, thermistors, control panels, and other devices to provide better control of the heating process and safety. Thermostats prevent overheating by blocking the flow of current if the maximum allowable temperature is reached. These features are hard to incorporate into fuel-powered heaters.

Differences from other electric heaters

Electric heating elements made of resistance wire also have a positive temperature coefficient of resistivity, but do not increase their resistance enough to be self-regulating; they are typically used with the wires red-hot. The ceramic, on the other hand, increases its resistance sharply at the Curie temperatures of the crystalline components, typically 120 degrees Celsius, and remains below 200 degrees Celsius, providing a significant safety advantage. Ceramic heaters also have thermostats that switch power to the PTC array on and off in response to the temperature of the room, like other types of heaters.
