The prefix infra derives from the Latin word which means below. Thus, infrared means below red, indicating its position in the electromagnetic spectrum. Red is the color of visible light. Infrared is invisible to the human eye.
Also the sun produces many different type of rays (from Microwaves to Visible Light and X-Rays, see graph above). Only rays which fall in a certain spectrum (0.75 to 15 microns) do the heating. These rays are called Infrared Rays (A) Near-, (B) Medium- and (C) Far IR Rays. The best and most efficient spectrum for heating is the C Spectrum (Far IR rays, 6 to 10 microns).
Therefore, it is important that an infrared panel heater produces most of its IR rays in this optimum spectrum. INFRAPOWER panels produce 99,82% of its output in the C-range and more than 90% of it in the optimum spectrum of it (6 to 10 microns, see test report from Seibersdorf Laboratories, Austria).
CELINE POWER reaches this optimum spectrum with a patented formula of a very high grade Carbon Nickel mixture (developed by Austrian technicians) and a Nano Silver conductor (developed by Japanese technicians). All coated by dielectric layer and 100% PE protection. A unique reflector technology emits all IR to one side (no loss to backside, backside gets hot but no IR rays to backside).
Simple Test: Hold hand 2cm behind the panel and you will not feel heat. No IR rays are emitted to the backside through INFRAPOWERs unique reflector technology (optical mirror layer applied).
