Below is a list of Infrared Dryers manufacturers from St. Paul, Minnesota. Infrared dryers remove moisture from substances, materials and parts using electromagnetic radiation between 0.7 and 300 micrometers (µm) in wavelength. Infrared rays are just one part of the electromagnetic spectrum, which also includes gamma rays, x-rays, ultraviolet rays, microwaves and radio waves. Infrared rays have a longer wavelength than visible light and therefore cannot be seen. They can, however, be felt.
