Below is a list of Infrared Heating Elements manufacturers from Streamwood, Illinois. Used in infrared heaters, infrared heating elements run electrical currents through specially prepared resistors in order to convert electrical currents into infrared rays. These infrared rays may be short, medium or long-waved depending on the application and the distance. In addition, infrared rays are able to easily travel through air as well as being absorbed naturally by dense materials such as wood or skin.
