Infrared heaters use a reflective shield to direct radiant heat onto a heated surface.  Common types of infrared heaters include metal-sheathed tubular heaters, quartz tubes, quartz lamps; gas fired catalytic, flat-faced panels and ceramic emitters.  Infrared flat panel heaters are used to heat objects via radiant heat transfer.  Infrared heater elements are replacement heater elements used with radiant flat panel heaters and radiant reflective heaters. Replacement elements are of the same types and configurations used in full heating systems.  Infrared reflective process heaters use a reflective shield to direct radiant heat onto a heated surface. Many infrared reflective process heaters are so precise that heat can be directed to pinpoint locations.  Infrared reflective process heaters are used in food service, as well as in a variety of other applications.
