Infrared heaters: as good as heat from the sun!

BURDA infrared radiant heaters and ‑systems offer all climate solutions from one single source

As a pioneer in the field of short-wave infra­red tech­no­lo­gy, BURDA WTG has the bene­fit of over 25 years of pro­duc­tion expe­ri­ence. Sin­ce the ear­ly days, our hea­ters have deve­lo­ped into very effi­ci­ent high-tech sys­tems, used in prac­ti­cal­ly all con­ceiva­ble are­as. Indoors or out­doors, for house­hold, com­mer­ci­al, indus­try and public envi­ron­ments with per­ma­nent or tem­pora­ry instal­la­ti­ons, from sin­gle units up to mul­ti­ple instal­la­ti­ons. With offer opti­ons with ligh­t­ing , heat con­trol with blue­tooth and our uni­que and paten­ted hea­ting & coo­ling sys­tems for vir­tual­ly all are­as and envi­ron­ments.

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
