Item Component Description
1 Lamphead with
external blower
The lamphead consists of a bulb housing, UV bulb (4), wave guide,
reflectors (3), light detector, starter bulb (5), and the magnetron (6)
assembly. The patented wave guide couples RF energy to the bulb
and provides cooling for the bulb. The lamphead reflects the emitted
UV light onto the substrate. 225 CFM @ 2.5 in. W.C. of cooling air
from an external source is required at each lamphead.
NOTE: For more information on the lamphead, refer to the CW306
Lamphead manual.
2 Lamphead with
internal blower
This lamphead is the same as the external blower lamphead but
contains an internal blower to cool the UV bulb and magnetron. The
internal blower is sized to provide a minimum of 225 CFM at 2 in. W.C.
NOTE: For more information on the lamphead, refer to the CW306
Lamphead manual.
7 External Blowers
for Cooling
External blowers are used to cool the UV bulb and magnetron on the
external blower lamphead. The lamphead requires approximately
225 CFM at 2.5 in. W.C. of cooling air per lamphead in order to
function properly. The external blowers must be sized appropriately to
provide adequate cooling air.
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. Refer to Power
Supply on page 3-1 for details.
9 RF Detector An RF detector monitors microwave energy levels. The system will
shut down when RF levels above 2mW/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. Refer to the RF
Detector on page 3-2 for details.
NOTE: The CoolWave lamphead produces heated
air and ozone, which must be safely ventilated
away from the work area. (Refer to page 1-5 for
more on ozone gas.) The minimum ventilation
requirement for each lamphead is 125% of the
cooling air or 280 cfm @ 2-in. W.C. to properly
evacuate the heat and ozone from the lamphead.
