The advantages in detail

Since our infrared radiators emit in the optimal infrared spectrum (infrared B or infrared C), the radiation is not only particularly pleasant for human skin, but also very well tolerated. Due to the direct radiant heat, dust whirling is avoided.

Infrared heating

To put it simply and without much technical ado, infrared radiation is radiant heat that heats people or objects directly without significantly affecting the surrounding air temperature. The heat therefore arrives specifically where it is needed. Learn more about it here!
