HIGH EFFICIENCY WITH THE BLACK QUARTZ FACE
The Casso-Solar Infrared Heater® Type “FB”, is 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 wavelengths of 2.5-6.0 microns. This corresponds to emitter temperatures of up to
1600°F (880°C) and 25 watts per square inch (3.9 watts per square centimeter). The quartz surface acts like a thermopane window, isolating the emitting source within, from the ambient surroundings, minimizing convection losses. Efficiencies of up to 80% can be realized in converting electrical power input to usable radiant energy.
MATCHING THE HEATER EMISSION TO THE PRODUCT
Like all Casso-Solar Infrared Heaters® , the Type “FB” can be tuned to match the peak absorption point of the material being heated. With the large surface areas available and the special coil layout design, uniform radiation on the product is achieved.
MAINTENANCE AND DOWNTIME MINIMIZED
The simple, compact and sturdy construction of the “FB” heater allows it to be utilized in most applications. It does not require external reflectors to be cleaned or replaced and there is no reduction in radiant output over its life. The “FB” heater is resistant to vibration and shock, due to its one piece bonded construction.
EASY TO INSTALL AND OPERATE
Standard “FB” heaters are available in convenient, lightweight, building block sizes. All standard heaters are provided with mounting studs and all necessary mounting and wiring hardware. Heaters can be mounted to radiate in any direction. In most applications, the “FB” heater can be positioned as close as 2" from the work, reducing the
overall system size and construction costs. The “FB” heater can be accurately controlled with a closed loop time-proportioning
temperature controllers. Standard thermowell heaters are provided with two locations for the thermocouple. The low mass of the heater allows rapid responses to requested changes in emitter temperature and minimized initial warm-up.
VERSATILITY IN SIZES, WATTAGES AND VOLTAGES
For most customers, we offer standard economical building block sizes. These standard heaters are stocked in both 15 watt per square inch and 25 watt per square inch power densities. Depending on size and total wattage, stock heaters are available at 120, 240 and 480 volts. Special sizes can be designed to system requirements, up to 25 watts per square inch and 600 volts. Custom housings, mounting attachments, wiring components, etc. can be provided.

	EMISSION OUTPUT CURVE The emission output curve at the left shows emitter temperature versus watt density and the corresponding wavelength emitted for a specific emitter temperature. For example, an emitter temperature of 12400F would correspond to a peak wavelength of 3.0 microns with a free air watt density of 15 watts per square inch. The key to efficiency is to select the emitter wavelength that best matches the peak absorption of the product to be processed.

WARM-UP CURVE The warm-up curve at right shows the response time of the Casso-Solar Infrared Heater®, Type FB, as measured by the thermocouple, from a cold start to a maximum temperature, for a 25 watt per square inch heater. Changes in temperature, or partial warm-up, will be along this characteristic curve.
