Radiant Emission Patterns of Ceramic Emitters

Salamander
ceramic emitters are manufactured with three basic emitter faces: concave, flat, and
convex. These emitter face styles will result in the specific radiant emission patterns as
shown above. Note: Infrared radiation is emitted at right angles
to the emission surface.
Concentrated: The concave surface will emit a "concentrated"
radiant pattern which is highly effective when zone heating is desired as well as radiant
heating in general.
Uniform: The flat surface will produce a "uniform" pattern for
even heating at a close proximity between the emitter and the target being heated.
Wide Area: The convex shape gives off a "wide area" pattern which
is desirable in comfort heating or other applications that require a dispersed radiant
emission pattern.

Salamander Radiant Emission Grid
The
Salamander radiant emission grid can be used to determine the proper ceramic
emitter spacing when used in an application such as an infrared panel. In order to achieve
an even heat pattern it is critical that the emitters are spaced so that their radiant
emission patterns overlap when reaching the target. The more overlap that occurs, the more
even the heat will be across the face of the product being heated. The area of highest
radiant emission intensity for a single emitter is shown within the two dark crossed lines
on the grid. In order for element emissions to overlap, the dashed line shows an
intersection point at a distance of 7" will occur if the emitters are placed a
distance of 2" apart from edge to edge. This same concept should be used to either
determine the distance to place the product if using an existing panel, or placement of
emitters if building a panel to guarantee radiant emission
overlap.
