What are EREMA (silicon carbide) Heating Elements and Industrial Furnaces?

The flat glass used in smartphone liquid crystal screens is made in a gas or oil furnace. It comes out of the furnace very hot and needs to be cooled down slowly. EREMA heating elements are responsible for that delicate temperature regulation. In 1927, EREMA became the first silicon carbide heating elements to be sold commercially in Japan. We have been improving their quality ever since and are now the biggest producer in the industry. Industrial furnaces are used to heat, melt and sinter glass, ceramics, electronic components, metals and powders. As a comprehensive manufacturer, we design and manufacture industrial furnaces as well as the heating elements and refractory materials that go in them. From small test furnaces to large scale industrial equipment, we enlist a wide range of technologies to produce furnaces and related products for all fields.

Applications

Industrial Furnaces

We custom manufacture all our industrial furnaces. In our design process, we insist on the following.

  • ・We select and computerize factors such as temperature, atmosphere and pressure appropriate to the product processing software.
  • ・We endeavor to automize product insertion and removal and to save on energy and space.
  • ・We prioritize safe design.
