Abstract (en)
The device has trapezoidal shaped heatable profile strips (2) including electrically conducting heating foils (4). The foils along with air ducts form a block (5). Air to be heated passes through the air ducts, and a temperature sensor measures the temperature of the air. A current switch controls the switching-on or switching-off of the device by using a relay when the air temperature value exceeds or is below a threshold value.
