Flat Panel Infrared Heaters

General Description
Flat panel infrared heaters are comprised of a resistance wire elements embedded in a body of ceramic base material. This construction guarantees a reliable infrared radiant emitter because the resistance wire can be “casted” into the surrounding ceramic base material. The element is backed by layers of insulation to minimize back heat loss. They are typically mounted into heavy gauge aluminized steel and can be mounted as close as 2 – 4 in from the material. Gas catalytic heaters (instead of electric heaters) are gaining popularity because of their huge potential economic advantages, especially for lower temperature applications such as drying.
The flat panel advantages versus other radiant heating elements such as quartz tubes, metal sheathed tubular heaters or ceramic is the complete, wide area, uniform coverage provided.

The emitter face is available in:

This infrared heater has a woven quartz cloth surface, finished with a black ceramic coating for high emissivity. The quartz face has the properties of being transparent to the infrared energy generated within the module, over the usable wavelenght of 2.5 - 6 microns. This corresponds to emitter temperatures of up to 1600 degF and 25 Watts per square inch. This type "FB" heater can be tuned to match the peak absorbtion point being heated. This standard flat panel heaters are manufactured in different sizes and different wattage.  Power to the infrared heaters need to be provided through SCR's and process temperature is best controlled by a Pyrometer (also known as "spectralmeters" or "IR sensor").

Type C and type C+ infrared heaters

This type of infrared heater has the backside of the used quartz emitter plate specially grooved to generate the required characteristics demanded by the heater. Resistance coils are placed in the grooves, being surrounded on three sides by the fused quartz window, maximizing the energy output of the infrared heater. This construction increases efficiency up to 89% and consequently reduces power consumption up to 50% compaired to conventional infrared heaters. This infrared heater emitts energy in the 2.5 - 6 micron wavelength which corresponds to emitter temperatures of to 1750 degF and up to 40 Watts per square inch for type "C" and 50 Watts per square inch for type "C+". Power to the infrared heaters need to be provided through SCR's and process temperature is best controlled by a Pyrometer (also known as "spectralmeters" or "IR sensor").

White quartz

This infrared heater is designed as a replacement for less efficient ceramic infrared heaters. (This type of heater provides 30 - 50% more usuable energy than standard type ceramic infrared heaters)  The fused quartz emitter face is similar to the type "C" infrared heater. This IR heater features tunable emissions to match the peak absorbtion point of the material being processed, and are designed with an internal refractory, eliminating the need for external reflectors. The heater face is self cleaning with a life expectancy of up to four times that of ceramic infrared heaters. This single phase (120V / 240V) heater will go up to 1700°F and allows for up to 40 W / sqin.

Panel heaters are available in wide range of standardized sizes, which make them suitable for many applications.

This type of heater produces medium wavelength radiation. It is a fantastic choice for drying and curing of different material.
