Energy saving infrared-heaters

For more than 35 years, Krelus AG has specialised in the supply of tailor-made infrared heater systems for applications such as:

  • Converting of paper, films and foils
  • Textil, film, paper and foil coating
  • Thermoforming
  • Embossing
  • Laminating
  • Pre-drying and heating equipment
The Krelus technology applies direct radiation from the heat source to the product. The special heater construction effectively blocks the heat loss to the reverse side of the heater. The fast medium-wave infrared-heaters allow operations with precise temperature control on product surfaces, says the company. Due to the rapid reaction time of these infrared-heaters, they can be switched off even for short breaks. With the optimised emission of the heat energy in the real medium wave range (+/- 3 microns) - where almost all products have best absorption - the infrared-heaters are more efficient and superior in comparison to traditional infrared-heaters and allow energy and cost savings, says Krelus.
The company has now extended its range of made-to-measure infrared-heaters with four standard models. Using identical technology, the company is now able to supply the sizes 248x248mm, 123x496mm, 123x248mm, and 78x396mm. These four new types of modules allow individually controlled radiation zones to be easily constructed to any desired size. These new infrared-heaters are of course particularly suited for use in thermoforming equipment and on continuous running lines to give accurate and consistent temperature profiles, says Krelus.
