Modular Light Shield Systems
MLS Systems
Low Cost And Quick Delivery
Fusion UV’s Modular Light Shield (MLS) system is a new and innovative approach to building light shields for
web or conveyor applications which permits a more cost-effective solution with quick delivery without sacrificing quality,
performance, versatility, features, and appearance. The MLS is a deviation from the conventional custom engineered
systems with complex sheet-metal welded components uniquely designed for each project. No longer is this a time
consuming and costly approach.
The MLS system is a pre-engineered platform that uses a series of aluminum extrusions and other
common components which are quickly and easily configured and assembled to meet your unique requirements.
The aluminum extrusions, designed by Fusion UV engineers, serve three primary functions: lamp support,
UV light containment, and air management for safe and proper operation of Fusion UV microwave-powered lamps.
In addition, its compact profiles minimize the overall size of the UV system for maximum use and ease of installation.
The MLS system is adaptable to virtually any process width and
UV energy requirement. The MLS system allows for easy configuration
or addition (factory-or field-installed) of features such as bottom
water-cooled plates or air intake louver for heat-sensitive processes.
Quartz windows can be installed to isolate lamp cooling air from
substrate. External snouts can be added for further reduction
of light outside the unit.
The MLS system provides a proven solution to the high
demands of today’s UV curing industry and production
environments. It is constructed with high quality robust
materials, which makes it suitable for even the most extreme
operating environments. The compact size allows for quick
and easy installation. Easy internal access and
removable components simplify maintenance and
operation. Its best features are fast delivery at a
reasonable price!
As a result of the acquisition of
Fusion UV by Heraeus Noblelight,
the name of the company changed
from Fusion UV Systems Inc. to
Heraeus Noblelight Fusion UV Inc.

Modular Design
The patented MLS system allows a light shield to be
assembled in a fast and efficient manner. Extrusions are
cut to the length that is required for the process and
then bolted to endplates to form the primary lightshield
structure. It is completed by the addition of other
standard components that include interior heat shields,
access doors, bottom shielding, and mounting brackets for
the RF detector(s).
Multi-row MLS systems are assembled by joining
individual single row units. A single exhaust duct
connection is required for each single-row or two-row
system.

and bottom double air-intake louver
Standard MLS systems are available for web widths
of 6" - 60", and custom systems can be built for web
widths up to 100". The modular concept is a costefficient
platform for planning future
capacity requirements. It is
necessary to install only the number
of MLS units that will be occupied
with lamp systems. Additional MLS
units may be installed at a time
when production requirements
dictate expansion. The
modular platform offers
a solution that fulfills the
current and future needs
of the end-users in a
timely and affordable
manner.
Lamp Orientation
Shown with quartz window
and bottom water-cooled plate
MLS systems are available to support lamps in any
orientation for processing webs traveling horizontally,
vertically, or at any angle. Bottom-curing configurations
are also available, where the lamps are hung to direct the
light upward to expose the bottom of a horizontal web.
Multi-row systems that require curing top and bottom of
the web are easily configurable.
Bottom Cooling Options
Three bottom shield/cooling configurations are
available for web systems. A bottom heat shield
combined with a bottom plate is recommended for
processing opaque materials or less heat-sensitive
substrates such as paper. For heat-sensitive films, bottom
air cooling is recommended. This is accomplished by
installing a double layer of air-intake (light-tight) louver in
place of the bottom heat shield and bottom plate. If a
heat-sensitive web is being run under low tension and
cannot tolerate air movement, a stainless steel watercooled
plate can be easily installed in place of the double
layer of louver. The design of the bottom extrusions allows
the bottom cooling hardware to be easily assembled in our
factory or changed in the field for process modifications.

Quartz Window
Some applications may require
a quartz window to be installed between the
lamps and the substrate to isolate the
lamp cooling air from the substrate.
Quartz plates are mechanically held in
an aluminum tray which simply slides
into grooves on the extrusions. The
quartz window is positioned about 1
inch below the lamp. It can easily slide
in and out of the system for ease
of maintenance. A hinged
access door with a tooloperated
latch is provided on
the front and/or rear side
of the light shield for
quartz window removal.
Compact Size
Another significant benefit of
the MLS design is that the entire light
shield assembly is very compact without
adversely affecting safety, operation, and
performance.
By minimizing the overall size of the system, this
makes it easy for the end-user to install the unit
into tight spaces. The overall length of a singlerow
system (without external snouts) in the
web direction is 14.25 inches (or 362 mm).
A two-row system will simply be double
that of the single-row system. The height
of the light shield (not including the lamp
and ducting) is 9.50 inches (or 241 mm).
The width will vary depending on number
of lamps per row.

Other Features
• MLS light shield supports all Fusion UV microwave-powered lamps.
• External tunnel shields (snouts) can easily bolt on for additional light containment.
• Idler roll (3.5 inch dia.) assemblies, which are dynamically balanced to 1500 fpm web speed,
can bolt onto the substrate entry and exit end for additional web support.
• Mounting feet can be provided for installation on a horizontal
mounting surface.
• Supply and exhaust air plenums can be provided for
air handling.
• Focus adjustment bars fit into lamp boot, which allow the
user to easily vary the distance from lamp to substrate
for process variations.
• Focus adjustment bars for bottom cure system are
“sandwiched” between lamp and lamp
hanger rails.
• Outer finish is clear anodized. External tunnel
shields (snouts) are painted black.
• Construction uses all metric hardware.
Custom Systems
Fusion UV engineers can adapt the MLS platform beyond its standard capacity, and thus
design custom configurations and features to meet unique requirements.
