Item Component Description
1 Lamphead The lamphead consists of a bulb housing, UV bulb (2), wave guide,
reflectors (3), light detector, starter bulb (4), and the magnetron (6)
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.
7 External Blowers
for Cooling
The customer supplied 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: Lampheads with external blowers require a device to monitor
the air flow and static pressure. In the event of cooling air loss the
device will shut the system down.
8 Power Supply The power supply is fully modular. One power supply must be
provided for each lamphead. The power supply can operate as a
standalone system or part of a Master/Remote circuit.
9 RF Detector An RF detector monitors microwave energy levels. The system will
shut down when RF levels above 5mW/cm
2
are measured. Systems
operated as standalone units require one RF detector per power
supply unit. If multiple systems are networked then the master power
supply unit must be connected to one RF detector.
