The FOCUS HEAT^TM System uses infrared energy as its heat source. Infrared energy is thermal radiation consisting of wavelengths longer than those of visible light. It is part of the electromagnetic spectrum with wavelengths between 0.7 and 400 microns.

Infrared energy travels at the speed of light, is totally pure radiation, and can be transferred without physical contact with the heat source or heating the intervening air.

The energy is harmless and is transferred via invisible waves. When these waves strike the object to be heated, the radiation is absorbed and converted into heat energy.

The other major element of the FOCUS HEAT^TM System is the patented focusing grid. The grid is a lightweight stainless steel 1" x 1" x 1/2" deep device installed on the face of the emitter. The grid performs three functions. It acts as an insulator against heat losses, it triples the emitting area per unit area, and it redirects energy that would not normally hit the product.

The FCIR HEAT^TM System uses both convection and infrared energy as its heat sources.

The second major element of the FCIR HEAT^TM System is the employment of a convective energy heat source within the element. Convective heat is defined here as precisely heated IR delivered to the product in a controlled airflow. In the FCIR HEAT^TM System, The convective energy is directed to the work via a grid of holes drilled into the emitter face. The plenum is under positive pressure from a re-circulating blower (return is from oven tunnel). This assures that each hole in the emitter dispenses an equal flow of air into the tunnel. See figure 3 for details.

The CHIR HEAT^TM System employees the same emitter panel as the FCIR HEAT^TM System. In the CHIR HEAT^TM System the panel face is affixed to a high temperature glass panel. This system is primarily for use in ovens going into a clean room environment.
