Welcome to Krelus AG.

The fast medium wave KRELUS IR-heaters are superior

Due to the physical properties of almost all materials which can be treated by infrared, the medium-wave radiation in the range of 2,5 µm - 3,5 µm gets the best results. This is just the emission range where our KRELUS-IR-heaters gets the highest performance

Our modular and custom made IR-heaters leave all opportunities for the individual, almost endless applications.

The KRELUS-IR-heaters are working with the shortest reaction time ON/OFF. This guarantees the highest economical use of electrical energy and fastest adaption to required temperatures on product surfaces. Consequently our IR-heaters are highly active with gentle action for treated products and even more important: they are energy saving.

• highest energy efficiency
• fast respond ON/OFF
• no increased start-up current
• medium wave energy in the best absorption range
• continuously controllable from ambient to 850°C (1562°F) 2,5 µm - 9,6 µm
• power density up to 50 kW/m2 (5 W/cm2)
• full area heating / radiating
• modular sizes and custom made
• from 250 mm (10") to 9500 mm (374")
• all voltages from 10 Volt to 660 Volt
• fully controllable

• coating of plastic, textile, paper, etc.
• thermoforming
• activating of glue
• lamination
• melting of plastic powder
• curing of plastics (gelification)
• preheating before embossing
• welding of car parts (also in 3D)

generally: everywhere in the industry where the energy saving factor becomes important for the infrared application.
