An infrared ray reflective coating for application to insulative materials comprising aluminum particles in an aqueous acidic binder slurry, a hardener, and a coating cement having about 96% of a mixture of Al. sub. 2 O. sub. 3 and SiO. sub. 2.
A radiant heater modules comprises a plurality of quartz iodide bulbs projecting from an air cooled housing and a reflector to direct heat from the bulbs toward the pipe. This housing is of a generally box-like configuration and includes a top cover plate. The bulbs are mounted in sockets which are attached to the bottom side of the top cover plate and the sockets are electrically connected to a plug which is fixedly attached to the top side of the top cover plate. Means are also provided for rigidly securing the housing to the reflector.
A portable radiant heating apparatus includes a pair of linearly extending members pivotally attached to one another adjacent a first end thereof and pivotal about the pivotal attachment to be generally parallel to one another. A lamp receiving electrical socket supported on the other end of each of the members receives a high intensity infrared lamp electrically arranged to receive power from its socket via means for connecting each of the sockets to an electrical power source. A concave infrared reflective shield is provided about each of the lamps and shaped to direct the light from each of the lamps generally uni-directionally. Thermal insulation means are also provided to protect the members and shields from the heat generated by the lamps.
