FACE
OPTIONS
OPAQUE QUARTZ
is the standard face on the Q-SERIES panel heaters. For over 40 years,
Solar Products has been an original manufacturer of fused silica (opaque
quartz). The properties of quartz make for a very efficient radiator of
infrared energy. Our expertise with infrared heaters, combined with our
ability to fuse quartz allows Solar Products to be the only company in
the world to manufacture this unique heater. The back of each fused
quartz face is precision machined to hold the resistance coil. With the
coils resting in the grooves, the coils are surrounded by three walls of
quartz, thereby maximizing the energy output of the heater. A reflective
insulating fiber board is added behind the heating element to direct the
IR energy forward through the quartz face. Double layer insulation is
installed behind the insulating board to decrease back heat loss.
Aluminized steel casings and welded stainless steel terminations are
standard throughout.
Orientation of the Q-Series heater must be controlled. The heating
elements are not cemented in place. Therefore, it is important to assure
that the heating elements are not placed in a vertical orientation. This
will result in slumping of the coils and a greatly reduced life
expectancy. |

Q-SERIES
SPECIFICATIONS
Dimensionally, the heater can be as wide as 12" (305mm) and as
long as 24" (610mm). A more common dimension is 12" (305mm) x
12" (305mm) or smaller, for this series of heater. The QP model has
a maximum watt density of 40 wsi (62 kw/m2). The QH model has
a maximum watt density of 60 wsi (93 kw/m2). Durability is
defined by a typical life expectancy of 25,000 hours. The heater has a
high radiant efficiency of 82%. Because the heater design does not
depend on an external reflector, the heater maintains efficiency over
time. The Q-Series heat transfer rate at 60 wsi (93 kw/m2) is
6.04 Btu/sq. ft./sec. delivered to the product. |

| There
are two grades of quartz available in the Q-Series heaters. The QP model
uses 98.5% pure quartz and the QH model uses a very high purity 99.998%
quartz. The QH model is often used for semiconductor applications due to
the high purity level of quartz, the temperature uniformity, and the
ability to create unique shapes. The Q-Series heater is additionally
used in many applications that require high intensity heat, such as high
speed drying or curing lines.

Q-Series
Panel Heater - Models: QP and QH
The Q-Series line of IR panel heaters offer the highest power density
output available in an IR panel heater. High purity, fused, translucent
quartz is used as the emitter face. |
