DEWEIT produces energy-saving thick-film heating elements (of any shape, power and voltage) having increased reliability and saving up to 40% of electricity compared to traditional heating elements.

DEWEIT heaters are able to intense, directed thermal (infrared) radiation, providing an opportunity to create efficient, compact, mobile, heat registers, calorifiers, convectors, dryers, heat guns, air curtains, fan heaters and infrared heaters. Direct heat transfer from the heating film to the heat receiver substrate provides a quick exit of the heating element to the operating temperature due to the extremely low structure thermal inertia.

Conductive pastes’ composition without the use of precious metals for heating elements has been developed by DEWEIT, which made it possible to make products available for use not only in industrial, but also in domestic heating equipment.

  • The DEWEIT heating elements’ design allows you to convert electrical energy into heat more efficiently due to the directed heat flow, avoiding heat dissipation (in different directions)
  • The DEWEIT form factor of heating elements makes it possible to create heating elements of any flat shape
  • The increased heat transfer area allows you to reduce the heater temperature, which significantly increases its term of exploitation
  • DEWEIT heating elements have a posistor effect, that is, their resistance increases when heated, the surface temperature rises, and the power consumption decreases
  • DEWEIT heating elements emit a long-wave infrared flux being most appropriate to human physiology
  • The heating elements’ technical parameters (supply voltage, power, operating temperature) can be varied over a wide range without changing the heater design, only by changing the resistive paste rated power. You can create several electrical circuits with different technical parameters on one substrate.
