efficient responsive modular economic The fast KRELUS infrared heaters

Leister’s KRELUS infrared heaters emit medium wave infrared radiation. This is particularly well absorbed by plastics, paper, wood and water. Special metal foils are used as emitters to ensure homogeneous energy distribution and high efficiency. Intensities of up to 60 kW/m² are achieved. Heater field, combined of different modular infrared heaters The outstanding properties apply both to modular heaters, which can be individually combined into heater fields, and to specific heaters, which are custom-made. Characteristics • very short reaction time • very good controllability • high...

KRELUS Infrared heaters Quartz heaters Ceramic heaters Radiation heating The infrared radiation is a part of the electromagnetic spectra and lies between the visible light and the microwave radiation in the wavelength range of ~1 1000 – µm. The technically relevant range for heating is typically given as 1 – 10 µm. A wavelength under 1.4 µm is referred to as short wave, between 1.4 µm and 3 µm as medium wave and over 3 µm it is called long wave radiation. Emission spectra of infrared heaters Relative intensity 1.0 1750°C 0.9 0.8 0.7 1550°C When the radiation interacts with material,...
