What is infrared?

Infrared radia­ti­on is a sub-area of the light spec­trum gene­ra­ted by the sun. This type of light, howe­ver, is invi­si­ble to the human eye; it only ser­ves to radia­te heat. This means that infrared rays, respon­si­ble for the human sen­sa­ti­on of heat, are posi­ti­ve rays and can­not be com­pared with UV or micro­wa­ve radia­ti­on or with X-rays.

Owing to their vary­ing wave­lengths and resul­ting mode of action, a distinc­tion is drawn bet­ween three types of infrared rays:

Infrared-A, short wave
780 – 1.400 nm (0,8 – 1,4 µ) 3620 K – 2070 K

Infrared-B, medi­um-wave
1.400 – 3.000 nm (1,4 – 3 µ) 2070 K – 965 K

Infrared-C, long-wave
3.000 – 10.000 nm (3 – 10 µ) 965 K – 290 K

Advantages of infrared heating!

  • Instant heat: 90% of the heat is available in short wave (IRA) within one second. Medi­um and long wave emit­ters (IRB and IRC) requi­re a lead time of up to a maxi­mum of 20 minutes.

  • Effec­ti­ve: 92% radia­ti­on effi­ci­en­cy! Over 85% of the ener­gy is con­ver­ted to heat. Medi­um and long wave radia­tors release some of the heat ener­gy to the cir­cu­la­ting air (con­vec­tion heat)

  • Low bud­get: free of maintenance

  • Pre­cise: Heat can be direc­ted in any direction

  • Ver­sa­ti­le: Even par­ti­al are­as can be effec­tively heated

  • Per­for­mance: Wide power ran­ge up to 18 000 watt

  • Cus­to­mi­sed: Inten­si­ty adjus­ta­ble from 0 – 100 %

  • Relia­ble: Life span of tubes up to 5,000 h – even with con­stant swit­ching on and off

  • Secu­re: Shock­pro­of due to use of quartz tubes

  • Envi­ro­m­ent:  Hard­ly any emis­si­ons and no oxy­gen consumption

  • Clean: No pol­lu­ti­on from blasts of air or dust
