Ceramic Cartridge Heaters

Ceramic Cartridge Heaters

Elmec Ceramic Cartridge Heaters are custom made and are used in various applications including heating of Ovens, Dryers, Water and Oil heating. Ceramic cartridge heaters are good at places where indirect heating is required. We have developed heaters to a maximum capacity of 320 KW. Ceramic cartridge heaters assembled in SS 304 tube sheath and assembled to ANSI flanges of various sizes for oil heating applications.

We use high quality ceramic insulators, Nichrome / kanthal D resistance wires.

We can also supply with outer casing and flange of thread type or disc type as per customer specifications. These heaters come with screw terminals.

Elmec Ceramic cartridge heaters are used by leading OEMs and Cement, Pharmaceutical, Food processing, Metal processing industries, plating shops. We are supplying to Indian and overseas industries / markets.

Do's and Don’ts
  • Please take care while fixing heaters and selecting watts check Volts rating of heaters before connection. Heater rated for particular volts should never be connected to higher volts rating.
  • These heaters are flexible and heat transfer is by conduction from inside surface so perfect matching of dia is important.
  • No foreign materials such as polymer, oil, water etc, should fall over the heaters. They should be well covered.
  • Choose appropriate watts as per calculation. Under rated watts will result in heater failure.
  • Temperature control should be taken care. For higher temperature application do inform us while ordering.
  • All heaters come with internal ceramic fiber insulation for energy saving. Additional cover can be provided upon request at additional cost. Do infor at enquiry stage. Good only for sizes bigger than 100mm dia.

Frequently Asked Questions

Ceramic cartridge heaters are high-performance heating elements that use ceramic core insulation to deliver superior heat transfer, high watt density, and longer life compared to conventional cartridge heaters.

These heaters operate by passing electric current through a resistance wire wound around a ceramic core. The heat generated is transferred to the sheath and then radiated or conducted to the surrounding area, making them effective for both air and liquid heating applications.

These heaters are ideal for high-temperature industrial applications such as hot runner systems, injection molds, packaging machines, printing equipment, and scientific instruments requiring precise heat control.

Ceramic cartridge heaters are ideal for indirect heating because they transfer heat by both conduction and radiation from their outer surface, ensuring an even and efficient temperature distribution without direct contact with the substance being heated.

The ceramic core provides excellent thermal conductivity and electrical insulation, allowing uniform heat distribution while reducing energy loss and improving the heater’s durability.

Proper fixing and clamping are essential for efficient heat transfer. The heater should be placed horizontally unless specifically designed for vertical installation. The tube must be cleaned before installation, and the heater should be fully secured to avoid movement and ensure safety.
