EASE OF CONTROL
Through the use of time proportioning controls, with
closed loop feedback, product temperature can be maintained
within ±2°F across the web. A thermocouple is located within
a quartz thermo-well, to accurately measure the emitter temperature of
the heater. Power to the heater is provided through SCR power controllers
or solid state relays, with optical pyrometers further enhancing the process
control.
HEATER EMISSION MATCHED TO THE PRODUCT
Casso-Solar Infrared Heater®, Type “C” & “C+”,
has a tunable emission, to match the peak absorption point of the material
being processed. Special multi zone heaters can program a temperature
profile into the product, if desired.
DESIGN FLEXIBILITY
Each Casso-Solar Infrared Heater®, Type “C” & “C+”,
is individually designed to the application. Sizes vary from as small
as 2" x 2", up to 20" x 20", with the most common
sizes in the 12” x 12" range. Wattages are available up to
50 watts per square inch, with voltages to match the power supply up to
600 volts. Multiple zoning is available, as are special thicknesses and
custom mounting brackets, for easy installation.
REDUCED MAINTENANCE
The simple, compact and sturdy construction of the Casso-Solar Infrared
Heater®, Type “C” & “C+”, allows it to
be easily utilized in most applications. It does not require external
reflectors, which must be periodically cleaned or replaced, to maintain
high efficiency, nor does it require external cooling to prevent damage
to the heater terminals or wiring. The fused quartz surface is self-cleaning,
retaining high output efficiency throughout its long life.

With
new product and process technology under continuous development, production
equipment is required to give precise and flexible control over production
quality, while operating efficiently with minimum maintenance. For over
forty years, Casso-Solar Corporation has been providing our customers
the competitive edge. |

TRIPLE POWER WITH GROOVED
QUARTZ
Every Casso-Solar Infrared Heater®, Type “C” & “C+”,
has the backside of the used quartz emitter plate specially grooved
to generate the required characteristics demanded by the heater. Precision
resistance coils are placed in the grooves, being surrounded on three
sides by the fused quartz window, maximizing the energy output of the
heater. The grooving pattern defines the coil layout and secures the
coils in position, maintaining uniformity over the life of the heater.
These combined characteristics, along with accurate controllability,
can provide system efficiencies of up to 89%. Consequently, power consumption
can be reduced up to 50% on typical systems over conventional infrared
heaters and special applications can realize a 60-70% savings.
FLAT QUARTZ MAKES
THE DIFFERENCE
The Casso-Solar Infrared Heater®, Type “C” and “C+”,
incorporates a flat fused quartz emitter plate, manufactured through
a patented process, that has the characteristics of being virtually
transparent to the infrared energy generated within the module over
the usable wavelengths of 2.25-6.0 microns. This corresponds to emitter
temperatures of up to 1750°F (960°C) and 40 watts per square
inch (6.2 watts per square centimeter) for Type “C” and
50 watts per square inch (7.75 watts per square centimeter) for Type
“C+”. Being a very poor conductor of heat, the fused quartz
emitter plate acts like a thermopane window, isolating the emitting
source that is within the Casso-Solar Infrared Heater® module, from
the ambient surroundings, keeping convection losses to a minimum. The
Type “C+” Heater is made from a high purity quartz material,
allowing higher radiant efficiency and output.
