FP Flat Panel Infrared Heaters are very efficient infrared heat sources in that as much as 80% of the applied energy is converted into radiant energy. Typical ratings are 10-15 watts per square inch. The FP Flat Panel Infrared Heater's advantage versus radiant elements such as quartz tube, metal sheath tubular and ceramic is the complete, wide area, uniform coverage provided. A broad range of standard sizes and ratings can form the modular base of a radiant heating system. Custom sizes and ratings can also be designed for special or unique applications. The standard material, Quartz Cloth, a cleanable Black Glass and extra-durable Stainless Steel emitter surfaces are available. Because of the rugged construction, FP Infrared Heaters are resistant to shock and vibration. No reflectors are required, eliminating maintenance requirements. Without insulation, the overall thickness is 1-1/2" - with insulation, 3". Thermowells can be installed near the surface for precise control of the sheath temperature. By controlling the sheath temperature, the wavelength can be matched to the specific absorption characteristics of the material being heated.

Specifications:
Quartz Cloth, Black High Temperature Glass or Stainless Steel Emitter Surfaces.
Quartz Cloth and Stainless Steel surfaces have a black, high emissivity coating.
Stainless Steel Frame for continuous high temperature operation.
Minimum Frame dimensions allow little interruption in the radiant heat pattern
when two or more panels are mounted together. 5/16" of frame overlaps the
emitter's surface.
Refractory Board with Channels for mounting Resistance Helix.
1-1/2" is standard thickness; 3" thick units include High Temperature Insulation.
1/4-20 x 1" long Stainless Steel Screw Terminals. Standard position of terminals
depend on rating of heater. Terminal enclosure available.
10-32 Mounting Studs located in the corners and along the edge as required or
as specified.
Minimum Width - 4"; Maximum width - 24".
Minimum Length - 6": Maximum length - 70".
Standard 5" long, .24" I.D. quartz tube thermowell installed from the side slightly
off center of the panel. Special thermowells can be supplied.
Type K Thermocouple to monitor or control emitter surface temperature -
ordered separately.

Average Emitter Surface Temperatures:

Watts/Square Inch	Quartz Cloth Surface	Glass Surface	Stainless Steel Surface

15	1400°F (760°C)	1200°F (649°C)	1400°F (760°C)
20	1650°F (900°C)	1300°F (704°C)	1600°F (872°C)

An FP Panel Heater, positioned vertically, is energized in 70°F (21°C) ambient air. A Type K thermocouple is installed in a thermowell in the standard position next to the resistance element. A temperature control used in conjunction with the sensor and a solid state output will maintain the constant temperature required for the maximum radiant energy transfer to the process. This will also compensate for ambient temperature changes and voltage fluctuations.
