JTEKT Thermo Systems (previously Koyo Thermo Systems) produces different kinds of heating elements, which have a very low thermal mass, caused by their type of construction. A rather thin resistance heating wire is molded directly into a special ceramic material, following a patented process. The ceramic material also serves as an insulator.
- Since the heating wire is arranged in a deepening and molded into the ceramic, no contact to component parts inside the heater can take place at normal conditions, without effecting heating performance. No short circuit can occur when using metal components inside the heater.
- The life time is increased compared to other heating elements, where the heating wire is attached on the surface. This is the case since extension or deformation of the molded wire is prevented over the life span of the heating element.
- Using this procedure, thinner heating wires can be used due to the stabilizing effect of the ceramic.
- The result is a lower energy consumption during heating.
- By using a thinner heating wire and the resulting lower heat capacity of the heating element, the heater is less sluggish and can react more quickly to signals from the controller.
- This enables better temperature control, which has a significant effect especially at "low" temperatures of up to 400 ° C.
- The temperature uniformity is increased.
- In addition, an overshoot of the temperature at the end of the heating period can be prevented.
Two types of Moldatherm® heaters are available. The plain type is used in JTEKT Thermo Systems conveyor furnaces. It can be used also individually by the customer for the construction of special furnaces or furnace chambers or heating areas. The half cylinder type of the Moldatherm heating elements can be used by customers to design high temperature heating mantles for tubes. A tube-like heating element is used by JTEKT Thermo Systems in a special setup for the production of tube heaters for semiconductor tube furnaces. These special LGO heating elements for semiconductor furnaces, tube furnaces and diffusion furnaces are described on a separate page, called "LGO heating elements".
This heating elements can be used for temperatures between 140°C and 1200°C.
Please note that the heating elements can only be offered as spare parts for existing customers
