Infrared radiant energy is transferred through space by electromagnetic waves. It does not require the use of a conductive media; in other words, energy is directly carried from the heater to the product without the need for contact or a medium such as air. All the heaters in this section fall into the medium wave spectrum. This wavelength is absorbed very efficiently by plastics and water based products. This makes the heaters ideal for drying and curing paints, melting plastics and heating food products. Radiant Heaters are used for spot heating, continuous web heating, and indexing systems. From a small to a large installation, ASB Heating Elements Ltd. has the expertise to help you size the project and advise on the correct installation and control system required.
