The Tubular Electrical Heating Elements is the most adoptable of all the variations of Heating Elements.It offers wide scope of ratings, sheath materials and shape that can be applied to practically any specified temperature, whether heating solids, liquids or gases.
The construction of these tubular heater provide prompt formation of different shapes, providing a improved heat distribution, greater compactness  and easy installation and maintenance in all Industrial heating applications. (Conduction, Convection, Radiation heating)
Technical ceramics are advanced ceramic materials that help in making the any applications possible which were thought to be nearly impossible ever before. Thermostat and Control is a pioneer in the field of technical ceramics and all of its potential, along with the numerous innovations with ceramics materials. In common terms technical ceramics groups together a wide range of different ceramics materials whose properties have been synthetically optimized and matched to suit various industrial technical applications challenges.
Technical ceramics are being used in a wide variety of applications in the automotive industry, medical technology, electronics or general equipment and machinery industry.
Technical ceramics materials therefore are the best options in direct competition to metals or plastics and are used where these materials do not fulfill existing requirements.

Classification of Technical Ceramics

Technical ceramics can also be classified into three distinct material categories:

  • Oxides
  • Non oxides
  • Composite materials

The range of ceramic heater parts produced are Steatite Ceramic Interlocking Insulating Beads in various shapes and sizes, Steatite Sealing Bushes for sealing the ends of tubular type electrical heaters.

Steatite and Cordierite Ceramic Band Heater Insulators with single and multibores for manufacture of Electrical Band Heaters for plastic molding machines.

Ceramic Tubes and Formers with single and multibores in various patterns and sizes in Steatite, Cordierite and Aluminum Oxide materials.

High Alumina Ceramic stress relieving interlocking insulators for electrical Pre-and-Post - Heating mats.
The use of ceramic insulating components has become an absolute necessary in order to meet with today's requirements in the field of Electrical Heating Engineering Technology, due to importance of high temperatures, insulation, size limitations and safety standards.

In today's Automobile, House hold and Industrial appliances Ceramic parts are considered of most importance due to its typical properties such as, high temperature resistance, high die-electric, high mechanical strength and corrosion resistance.

Ceramic heater parts are produced from the proprietary developed ceramic recipes formulated from the most selected quality raw materials to ensure that the components possess all the necessary physical, chemical and electrical properties as per the international quality standards.

Most of the ceramic heater components are produced from the company's owned molding tools, however we welcome your enquiries for specific type components. We suggest before designing your end product, please consult us, to discuss about the component material, its geometry etc. to offer the components at an economical cost made from most suitable ceramic.

We provide all the necessary services required for developing suitable ceramic components for your application.
