VOLTAGE,
PHASE, AND OTHER OPTIONS
VOLTAGE
Solar Products is a custom manufacturer of heaters and can therefore
provide the heaters designed for all commercially or industrially
supplied voltages - 120, 208, 220, 230, 240, 277, 380, 415, 460, 480,
575, 600 or whatever voltage is required. In many cases, heaters are
provided in dual voltage. This helps to reduce the heater stocking
requirements. Dual voltage heaters must always be a derivative of two,
namely 120/240 or 240/480. There are some cases where three voltages can
be available. This is only true for heaters with a minimum of 6 heating
elements and 7 terminals. This wiring arrangement can be configured for
3 voltages and dual phase. Consult Solar Products for your specific
heater requirements. |

PHASE
Solar
Products can manufacture the heaters for single, three, or in some
instances dual phase. Consult Solar Products for your specific heater
requirements.
FREQUENCY
Fixed
resistance heaters operate independent of frequency with no change in
design. Therefore, frequency is not an issue.
FIXED RESISTANCE
The
heaters are all fixed resistance. This means that the wattage achieved
is a direct result of voltage applied. W= V2/R. If the voltage varies,
the heater wattage will vary by a squared relationship of the voltage,
unless properly controlled. Proper control makes use of a temperature
controller or a power controller that can maintain a constant power
output. Solar Products heaters are designed for hot resistance ensuring
true power output.
ZONING
The
heaters can be separated into multiple zones in one given panel. An
example would be the use of (3) 12" x 24" (305mm x 610mm)
zones in a 12" x 72" (305mm x 1829mm) heater or (2) 6" x
48" (152.4mm x 1219mm) zones in a 12" x 48" (309mm x
1219mm) heater. The heater would be divided up in this fashion to
accommodate different widths in a web application. Sometimes a heater is
divided up into an outer zone and an inner zone. A last option would be
to apply multiple oddly shaped zoned to match a specific heating
profile.
EDGE COMPENSATION
Another
option that is applied to infrared heaters is the use of edge
compensation. This approach places a slightly higher watt density along
one long edge of a 24" x 36" (610mm x 915mm) heater, as an
example. To help compensate for heat loss along that open edge, a higher
watt density is constructed into the heater design for reduced edge heat
loss.
DEPTH
There
is no standard thickness for Solar Products heaters. The most common
depth is 3" (76mm). Heaters are manufactured as thin as 1.250"
(32mm) and as thick as 6" (152mm). The heater depth is most often
determined by available space and/or a required back temperature.
WAVE LENGTH
The
wavelength output from Solar Products heaters ranges from 2.3 microns to
6 microns. Wavelength is inversely proportional to temperature. That is
to say, as temperature goes up, wavelength goes down. All heaters output
energy over a range of wavelengths as depicted in the Heater Output
Curves. Heater A displays a typical short wave heater. Heater B displays
a typical medium wave heater. Heater C displays a typical long wave
heater. All of the curves have one common characteristic. If a line were
drawn vertically through the peak of the curve, then the area left of
the line represents 25% of the total energy output being shorter than
the peak wavelength and the area to the right of the curve represents
75% of the energy at a longer wavelength than the peak. Solar Products
panel heaters output the majority of the energy in the medium
wavelengths when operating at higher watt densities and higher
temperatures. When the temperature is reduced below 900°F (482°C), the
majority of the energy falls into the long wavelengths. Medium
wavelength ranges from 2-4 microns. Long wavelength ranges from 4-1000
microns. The effective process heating range for long wavelength IR
would be from 4-6 microns. Six microns relates to a temperature of 500°F
(260°C). An infrared heater with a surface temperature below 500°F
(260°C) has little use in industrial process heating applications. |

and the typical positioning of the components. All options, however,
would not be used simultaneously on a production heater.
