Metal flat heater
High Temperatures – right where they are needed.
Metal flat heaters, designed for use in the temperature range up to 500°C, can be rapidly heated up and cooled down nearly as quickly as desired due to their robust construction and resistance to thermal shock*, without suffering any damage.
For higher temperatures of up to 1100°C our high-temperature ceramic heaters are used.
* Thermal shock refers to the destruction of a solid object due to rapid heating or cooling, as the resulting stresses in the material cannot be absorbed or dissipated quickly enough. The result is the failure of the component through fracture or bursting.
Basic structure of a metal flat heater
Metal flat heaters are manufactured using the so-called thick-film process. Multiple layers with various functions are applied to a metallic substrate using screen printing.
In addition to standardized solutions, our stainless steel substrates can also be custom-made and printed according to individual customer specifications. The conductive path is designed by our highly motivated team based on the desired performance data and tailored to the heater’s geometry. Custom solutions such as the precise integration of sensors are faithfully implemented from single pieces to large-scale production.
Cleanroom manufacturing, from substrate preparation to soldering the contacts, ensures the highest quality standards. The result is a durable and light-weight resistance heater with high energy efficiency. Our commitment to quality is completed by a functional test.

* PTC: positive temperature coefficient. As the temperature increases, the resistance also increases, thus regulating the flow of current. The heater’s temperature is autonomously regulated by this effect.

Mechanical protection as well as electrical and thermal insulation in one – Mica sheet made of micanite
Securing the heaters with screws carries the risk of mechanical damage to the functional layers of the heater. To evenly distribute the forces occurring during the screwing and to prevent a short circuit from the fastening to the heater, a micanite mica sheet is commonly used as a standard. This serves as mechanical protection and simultaneously guards against one-sided radiation from the side facing away from the body to be heated.
