Ceramic Heaters

A reliable source for Electric Heaters information and leading Electric Heaters Companies & Manufacturers.

Ceramic heaters are electric heaters that produce heat utilizing the resistive heating theory and a ceramic heating element consisting of a positive temperature coefficient (PTC). As current passes through ceramic materials, they have enough electrical resistance and thermal conductivity to create and conduct heat. In addition, they are powerful and long-lasting; as a result, they work effectively as a heating element. Read More…

Ceramic Heaters Ceramic heaters are among the most widely used electric heater varieties. Ceramic heaters are used as heating elements in a variety of configurations to provide conductive and radiant heat. Conductive ceramic heaters can be combined with aluminum nitride or other compounds to form warming plates or bonding instruments for medical devices and semiconductor applications. Stand-alone ceramic heating elements may be packed with magnesium oxide and terminated with lead or copper wires for use in a number of industrial applications.

Ceramic heaters are electric heaters that produce heat utilizing the resistive heating theory and a ceramic heating element consisting of a positive temperature coefficient (PTC). As current passes through ceramic materials, they have enough electrical resistance and thermal conductivity to create and conduct heat. In addition, they are powerful and long-lasting; as a result, they work effectively as a heating element.

Ceramic heaters' heating elements are made of pure ceramic substance, but most are composite composites encapsulating metal and ceramic components. The latter's ceramic sense functions as an insulator while also conducting heat to the environment, reducing the heat and energy losses incurred with uninsulated resistance wire. Depending on the ceramic's composition, when voltage is given to the semi-conductive PTC ceramic material, the power rapidly reduces as the temperature rises. The ceramic components come in touch with the aluminum fins and heat them. The air is heated by a fan blowing out across fins.

Types of Ceramic Heaters

Contrary to its name, the ceramic heater is a type of heater that is not composed of ceramic. Most ceramic heater components are made of plastic, with some metal thrown in. The ceramic heaters are of two types:

  • Convective Ceramic Heaters

    A ceramic heating element is incorporated in aluminum fins and baffles in convective ceramic space heaters. They use convection. A fan is placed to swiftly heat the area, which circulates and disperses the warm air throughout the space.

  • Radiant Heaters

    Radiant heaters use infrared rays to warm items and people in a room, not air. As a result, they're perfect for quickly heating specific areas of a space or warming individuals sitting in front of them.

Materials in a Ceramic Heaters

The ceramic heater has two types of materials as the heating elements:

  • Ceramic Fin

    Metal fins are joined to a single block of ceramic material which is then heated by an electric current, warming the fins. The fins then heat the air.

  • Honeycomb Disk

    The ceramic block is perforated with many holes. As the air passes through the openings, it heats up. Honeycomb disk heating components do not require fins.

How does it work?

Ceramic heaters may be divided into Convective and Radiant, as both work differently.

The Convective Ceramic Heater has a simple working procedure:

  • The connective form of the ceramic heater's heating mechanism uses electricity to heat a series of metal fins.
  • The mechanism will then transfer the heat to a ceramic heating element. Meanwhile, the heater unit also draws chilly air from the base heater.
  • Then it blows cold air over the ceramic and metal components.
  • After that, it will disperse the heated air into the room.
  • Most convective heaters have a regulatory fan to regulate the warm air around the room or surrounding area.

On the contrary, the Radiant Ceramic Heater is ideal for industrial usage due to its heat properties. It works as follows:

  • Radiant ceramic heaters also need electricity to heat the ceramic plate.
  • However, they do not utilize the fan to circulate the air in the room; they emit heat directly at items in their path.
  • The nearby items are at a lower temperature than the heat provided by the radiant heater. After a while of the heat being directed at the things, their temperature rises.
  • The radiant heater does not heat as efficiently as a convection heater but does heat for a longer time.
  • The heat is contained in objects, not in the air, which may fade away quickly.

Benefits of Ceramic Heaters

  • Electricity powers ceramic heaters, making them a clean heat resource.
  • Ceramic heaters are simple to use. They may begin heating spaces and items as soon as they are plugged in and turned on.
  • Ceramic heaters are entirely safe. Electric heaters have a lower fire risk than fuel-powered heaters, which entail combustion.
  • Ceramic heaters may be used to warm places and items practically and flexibly. These heaters can be used to heat materials and products in industrial machinery.
  • Ceramic heaters are small and light. Despite their small size, they can generate a lot of heat.
  • Ceramic heaters can be fitted with thermocouples, circuit boards, thermistors, thermostats, and other devices to control the heating process better.

Applications of Ceramic Heaters

Ceramic heaters are used for various applications in different industries; a few are listed below.

  • In the plastic industry, thermoforming and vacuum forming are used to plasticize sheets and rolls.
  • Ceramic heaters are used to shrink polymers in PVC paste lamination and welding.
  • These heaters are used in the drying process of Nylon and Perlon threads.
  • They are used for car bodies' epoxy to be stoked or when the steel panels need heat with a lacquer finish.
  • These heaters are also used for the preheating and vulcanization of rubber sheets.
  • Ceramic heaters can also be used for adhesive activation and paper coating drying.
