Item Component Description
1 Lamphead The lamphead consists of a bulb housing, UV bulb, wave guide,
reflectors, light detector, starter bulb, and the magnetron assembly.
The patented wave guide also couples RF energy to the bulb and
provides cooling for the bulb. The lamphead reflects the emitted UV
light onto the substrate.
2 Ultraviolet Bulbs
NOTE: The system warranty is void if genuine Nordson UV bulbs are
not used. Contact a Nordson UV representative for ordering
information.
The system uses medium-pressure mercury bulbs. The bulbs consist
of high-purity quartz and have various fills (including doped spectrally
enhanced metal halide) to produce light at different wavelengths.
Bulbs and controls are carefully matched to give optimum UV output
and wavelength requirements.
Use genuine Nordson replacement bulbs with this system. Alter-
native bulbs may damage the control or overheat the reflector
system.
3 Reflectors Refer to Reflectors on page 2-4 for more information. Elliptical
shaped focus reflectors are used to guide the UV light in a tight band
across the surface of the material being cured. The reflectors are
manufactured from borosilicate glass, with a dichroic coating to give
maximum UV reflectivity while minimizing infrared radiation.
NOTE: A wider band of light can be produced by using optional flood
reflectors. Contact a Nordson UV representative for details.
4 Starter Bulb The starter bulb acts as the ignitor for the ultraviolet bulb. The starter
bulb is powered with 220 Vac at the same time the magnetron is
energized. After the UV bulb reaches full power the starter bulb turns
off automatically.
5 Pressure Switch Sets the minimum lamphead pressure for cooling the magnetrons and
bulbs for each lamphead.
6 Magnetrons The magnetrons are 3 kW, 2450 MHz frequency generators that
convert high voltage electrical inputs to RF energy. The wave guide
cavity is designed to couple the RF energy with the UV bulb, thus
exciting a UV emitting plasma within the bulb.
7 External Blowers
for Cooling
External blowers are used to cool the UV bulb and magnetron. The
lamphead requires approximately 350 cfm at 7 in. W.C. of cooling air
per lamphead in order to function properly. The external blowers must
be sized appropriately to provide adequate cooling.
NOTE : Installation of a device that monitors the airflow and pressure
is recommended. In the event of cooling air loss the device will shut
the system down.
