Radiant Tube:
Radiant tubes are available in different forms, 'U' tube, 'W' tube,single linear tubes, double linear tubes, continuous tube
systems, etc., in a wide range of outputs, each to suit particular applications.
The radiant heater warms all solid objects and surfaces in its path. They are mounted overhead and produce infra red
radiant heat that is directed downward by a reflector.
