RF Detector
See Figure 3-2.
S
One RF detector is normally required for every
16 networked units within one curing enclosure.
However, some applications and systems may
require a RF detector on each unit. Contact
your Nordson representative for more
information.
S
Mount the RF detector so that the antenna
faces the lamphead screen and is between the
operator and the lampheads or the lampheads
and any opening (the major source for RF
leakage).
S
The minimum distance should be eight inches
to prevent excessive heat on the detector
surface.
S
Do not mount the RF detector directly below the
lamphead.

For RF detector connections, refer to RF
Detector on page 3-11.

Lamphead Cooling
Lamphead cooling is critical to the operation of the
lamphead. There are two types of lampheads
available:
Internal Blower : requires no external cooling
air.
External Blower : requires an external source
of cooling air ducted to each lamphead.
The following specifications must be maintained for
all applications at all times regardless of which type
of lamphead is used:
S
constant flow of cooling air through the
lamphead with no restrictions at the exit end of
the lamp face
S
a constant static pressure of 2.5-in. water
column from the inside of the lamphead to
ambient or the lamp face
S
225 CFM of airflow through the lamphead
S
280 CFM of ventilation airflow
If you are using an exhaust box or any other type of
lamp face attachment that can impede the airflow
through the lamphead, you must monitor the
pressure and CFM on the lamp face.
The specified cooling air static pressure and CFM
requirements must be maintained. If not, the life of
the lamphead will be greatly reduced with the
possibility of failure.
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.
For more information on lamphead cooling, contact
your Nordson UV representative.
