Introducing
our new line of, compact, high-efficiency ballasts.
We're pleased to introduce Hanovia's latest
innovation in UV ballast technolog y,
a new line of compact, high-efficiency ballasts,
the state-of the art in UV ballast technology.
Maximum usable power and peak electrical
efficiency Unlike previous generations,
Hanovia's compact mercury vapor
lamp ballasts require only half
the usual cabinet space, and operate
with far greater electrical efficiency.
The result: increased design flexibility
in a system that operates at 95%
electrical efficiency, requiring
less power to operate (reducing
heat) and producing the same output
to the lamp.
Operates from any standard linevoltage
Their compact size is augmented
by the ability to operate from
any standard line voltage or frequency,
resulting in costsavings for equipment
design and eliminating the need
to stock more than one ballast
for different line-voltages. The
unit's variations will run standard
mercury vapor lamps at 300 watt/inch
up to a 20" arc-length and
200 watt/inch bulbs up to a 30" arc
length.
These state-of-the-art ballasts
are also available in versions
to run spectrally enhanced additive
lamps and will work beautifully
with Hanovia's "Quick-Start" fast
warm-up system, reducing downtime
during re-starts.

Irradiator
The
design of the Canrad-Hanovia irradiator allows
cooling of the work surface, lamp seals, sockets
and reflector without over cooling the lamp.
The irradiator is a lamp housing/reflector
assembly. It supports the lamp above the substrate
and reflects the UV energy in an efficient
curing pattern.
The irradiator consists of a stainless steel housing containing a linear
reflector with an elliptical cross section. The sockets are placed
so that the lamp arc is in one focal point of the ellipse. For optimum
utilization of the reflected UV energy, the irradiator should be mounted
so that the substrate is in the other focal point.
For proper performance the lamp
must operate at a rather high temperature.
However, the end seals must be
kept cool. The high operating temperature
would tarnish and warp an ordinary
fixture. The stainless steel housing
is designed to form an air-cooling
plenum. Air is exhausted from the
fixture through openings near the
lamp seals. This serves to cool
the seals and the reflector without
over-cooling the lamp body tube.
The reflector is made of specially
processed aluminum which has both
high UV reflectivity (about 90%)
and resistance to tarnishing and
corrosion. Speciallydesigned irradiators,
to satisfy specific applications,
are also available.
Power
supply and electrical control:
A
special electrical system must be employed
to operate the mercury lamp. The lamp requires
high voltage to initiate the arc and lower
voltage to sustain it while it is operating.
A current-limiting device is also necessary
to prevent excessive current during the "warm-up" period.
In order to get uniform curing, the electrical
system should be power reg ulated, or "stabilized".
A stabilized system will provide constant power
to the lamp even with fluctuations in the line
voltage.
The power supply used in conjunction
with the UV curing lamp is called
a stabilized ballast. It consists
of a transformer and a combination
of inductive and capacitive reactance.
These ballasts provide constant
power - ±3% variation in lamp wattage
when line voltage varies - 10%.
Ballasts are available for operation
with the complete line of Canrad-Hanovia
200W/in and 300W/in lamps. Options
include unencased ballas (user
supplies switching controls) and
encased ballasts. These latter
types are enclosed in a stee housing
and include switches and controls
for all lamp functions. Either
type may be wired to provid lamp
operation at reduced power.
In multiple lamp operations, it
may be convenient to remotely locate
the ballasts and operate the lamps
through control stations near th
curing line. Control stations are
available from Canrad-Hanovia for
this purpose. This equipment includes
all necessary controls for complete
systems operation.
Shielding,cooling
and safety equipment
To
insure safe and proper equipment performance,
careful consideration must be given to adequate
cooling and shielding. The irradiator(s) must
be enclosed so that no UV light may be seen
from the outside. Each irradiator must also
be connected to an exhaust system in order
to cool the reflector and lamp sockets. The
rate of cooling should be such that the temperature
inside the enclosure does not exceed 120°F.
Refer to the irradiator data sheet for specific
cooling requirements.
- Irradiators
for lamps from 6 to 77 inches with side or
center cooling, shuttered or unshuttered.

principle of Ultraviolet Curing
"
UV Curing" is a photochemical process
by which monomers harden upon exposure
to ultraviolet radiation. A specifically
formulated monomer will polymerize when
exposed to ultraviolet radiation. This
UV "Curable" monomer includes
a sensitizer which absorbs UV energy and
initiates a polymerization (cross linking)
reaction in the monomer.

The
science of photochemistry is based on the interaction
of molecules with quanta of light to produce
unique molecular changes. The benefits of photo
chemistry are high yields and simplicity of
control. Photochemical systems are ideal for
free radical" reaction mechanism. Applications
are: Halogenations of organic compounds Production
of primary mercaptans Oxydations Isomerizations
Polymerizations Photolysis of toxic wastes
The products of industrial photochemical reactions
a re
agricultural chemicals, intermediates, caprolactam,
and vitamin D, among other substances. Photochemistry
is also used in the curing (polymerization
) of specially formulated printing inks and
coatings.
Hanovia
has introduced the totallypackaged photochemical
system to simplify installation and increase
operating efficiency. A photochemical system
consists of four elements: 1) The ultraviolet
source; 2) Support equipment; 3) Power supply;
and, 4) Electrical controls.
Ultraviolet
Source
The
ultraviolet source used in this system is a medium-pressure
mercury lamp. These lamps are powerful sources
of 200-400 nm ultraviolet radiation. In addition
to high efficiency, these lamps are characterized
by long-life and maintenance-free operation.
Lamps are available in operating power levels
from 1200 watts to 15,000 watts and arc lengths
from 12" to 77". Please refer to the
lamp product data sheet for standard lamp sizes,
Support
Equipment
The
support system consists of immersion wells, well
head assembly and well support equipment which
controls coolant flow and nitrogen purge.
The lamp is placed in a quartz tube,
sealed at one end, called an immersion
well. The immersion well assembly consists
of two quartz wells fitted one within
the other. The wells are provided with
heavy quartz flanges and are secured
into a #316 stainless steel head assembly.
The photochemical well assembly is submerged
in a reaction vessel which allows maximum
efficiency of radiated energy and prevents
the lamp from contacting the reaction
fluid. High-wattage lamps produce considerable
heat. Excessive heat may cause the formation
of deposits upon the outer surface of
the immersion well, or surface flash
on the inner surface of the inner well
which contains the mercury lamp. If either
of these formations should occur, a decrease
in transfer of radiant energy from the
lamp to the reaction medium results.
This transmission loss in radiant energy
can be prevented by using a cooling medium.
In this equipment filtered water at a
temperature not to exceed 150°F flows
through the space between the inner and
the outer well assembly at a rate of
1-to-4 gallons/ minute at a pressure
of 40 p.s.i. (depending upon lamp wattage).
The system is safeguarded in the inclusion
of automatic pressure switches and electric
circuitbreakers arranged to extinguish
the lamp if loss of coolant or nitrogen
occurs. The system ceases to function
until correct pres sures
are restored.
During operation the external surface
of the merury lamp attains temperatures
in the order of 500-600°C. These temperatures
can promote the ignition of explosive
vapors such as are frequently present
in the processing room. In order to prevent
vapor explosion by thermal reaction or
by electric sparks, the inner well, which
contains the mercury lamp, is maintained
at a positive pressure of 4 to 5 p.s.i.
nitrogen gas. This positive pressure
prevents seepage of explosive vapors
into the well. It also provides an inert
atmosphere for the lamp frame and the
external metallic parts of the lamp which
can be damaged by the formation of ozone
which occurs when oxygen is present.
Reaction speed is also enhanced with
the nitrogen atmosphere.
The immersion wells are secured and sealed at the top by the well head assembly.
This stainless steel assembly consists of the electrical junction box, the
nitrogen cap, the coolant cap, and the mounting flange.
