Design/Build Specialists
USA Coil & Air has been an industry leader in building
air handlers for both new and replacement applications for
decades. We bring all the newest technology to both the
design and performance of our central station air handling
units, and we offer extensive experience in design-build
and retrofit applications.
USA builds units that are a cross between standard air
handlers and custom units. We offer all kinds of options
and accessories that allow you to semi-customize your
unit. You can vary dimensions, add special sections, use
painted or galvanized sections, and just generally design
the unit that you need for your job. And the best part is that
youre not paying for a total custom unit. Youre getting
most of what you want at standard unit prices.
USA can tailor our selection to meet your requirements.
Our software is designed to offer you the equivalent of a
complete submittal at the time of our proposal to you. You
will get complete performance, dimensions and choices in
options and accessories. You will have a menu to choose
from, so that you can design the unit that fits your space
and meets your requirements for your specific job.
Also, many existing units fail to meet revised conditions
or systematic conditions that might mean that you require
new units to do your job. USA has a wealth of experience
in retrofit/replacement and nobody can do a better job of
walking you through the design of your new unit. We offer
suggestions and engineering recommendations that cre-
ate better performance, higher efficiency and longevity. Call
us and we will be happy to work with you on your next
project.

Access Panels and Doors strategically located to
allow for proper service and maintenance of unitary com-
ponents.
Extended Fan Bearing Lube Lines and Coil Con-
nections to easily maintain drain lines and keep air mov-
ing equipment lubricated.
Flexible Design
Modular Design that allows you to mix and match
sections to essentially build an air handler your way!
Flexible Dimensioning gives you the ability to de-
sign a unit and its components in a box size that meets
the dimensional criteria of the installation.
Indoor and Outdoor Construction available. If it is
on a platform, pad, steel or a curb, then we have a unit to
meet your exacting design.
Simple, Low Cost Installation
Bolted Frame Construction with easy to remove pan-
els
Simple Section Attachment via patented splicing
design
Gasketed Extended Coil Connections and Drain
Pan Connections that eliminate constant panel remov-
able and guaranteed air tight unit.
Operating Efficiency
Computer selected Components provide the high-
est efficiency at a reasonable first cost basis.
Solid or Perforated Double Wall Liners reduce con-
densation and air leakage
Double wall injected foam insulation increases
panel strength and R-value of R-13
Easy Service and Maintenance
Special Access Sections can be located between
any system components allowing walk in space or change
any item.
Low Leak Cabinet Design means youre providing
heated or cooled air to the intended space and not to a
remote area.
Low Leak Dampers reduce operating costs and sim-
plify installation.
Huge Offering of Adaptable Inlet and Outlet Sec-
tions that minimize the attachment of ductwork and re-
duces labor costs
Complete Drive Side Assembly to include custom
fan, motor drive and vibration isolation mounted and fac-
tory tested on a unit mounted steel base.
Galvanized Steel Cabinets or Painted Steel which
offers a quality option if a smooth appearance is required.
Ship Assembled or In Sections gives the installer
the ability to move units into place quickly and efficiently.
Special design is always a possibility to move units through
building openings to include fresh air, doorways, elevators
and stairs. In really tight areas, each section can be to-
tally knocked down and reassembled on site.
Expedited Shipping Schedules
Many projects require some form of quick shipment when
you need units for design-build or units for replacement.
Quick shipment is often your first thought. How do I get
the units on the job quickly?
USA offers quick ships on many of our units. Often we
ship central stations within a month. We cant offer every
option or accessory under this program, because that just
wouldnt be practical. We cant always do it, just based on
scheduling and backlog. USA, however, does a great job
of shipping quick when its possible. If we can help you
solve your problem with our quick ship program, then we
will. 4

Quality
For many years USA Coil & Air has been respected and
highly regarded for their fast shipment of high quality air han-
dling equipment. USA has taken a major step forward in re-
defining the indoor central station air handler. Demands for
improved indoor air quality, low sound, high operating effi-
ciency and smaller mechanical rooms require a better prod-
uct for todays air handler market. The USA Indoor Central
Station air handler has been designed to meet or exceed
these demands.
The key to providing such a high quality product is in the
basic design. The USA Indoor Central Stations unique con-
struction has been designed to provide unequaled thermal
efficiencies and to be airtight. In addition, USA Indoor Air
Handlers offer tremendous flexibility in sizing, component
options and unit arrangements to meet the indoor air quality
requirements, operating efficiency, sound and installation
requirements for todays extensive commercial and custom
markets.
Flexibility
By virtue of its unique frame design, the USA Indoor Air
Handler offers incredible flexibility. This is reflected in our
Variable Increment feature that allows USA air handlers to
be sized in two-inch increments (height and width) to fit the
available space. Numerous section and component options,
and the ability to arrange components in whatever arrange-
ment required, allow USA air handlers to be customized to
the requirements of each job without expensive field modifi-
cations. Finally, USA air handlers can be shipped as a com-
pletely assembled unit, in modules or by component sec-
tions for new or retrofit applications that require smaller sec-
tions for passage through the building.
Cabinet Construction
USA Indoor Air Handler cabinetry consists of a box-type
frame channel - the backbone of the unit - and easy-to-re-
move panels or hinged access doors. The unique, patented
frame channel design allows three identical pieces to be bolted
together to form a corner of the unit. Channels are formed of
G90 galvanized steel or G60 painted galvanized with factory
applied neoprene gasketing on all flanges to minimize ther-
mal leakage. Gasketing is also factory applied at all contact
surfaces between interior and exterior metal components to
minimize thermal bridging. Panels are secured to the unit
with fasteners that can be easily removed to access the unit
interior. The frame channel and panels can be easily disas-
sembled and reassembled, giving contractors tremendous
flexibility in installing and servicing the units - even where
space is very limited - saving time and money. Patented
splice joints help guide sections together for a tight fit, sav-
ing additional time and money on installation. Splice joints
are also fully insulated at the factory.
Access and Serviceability
Equipment must be designed to perform efficiently and
withstand the wear and tear of everyday use. It must also be
designed to provide easy access to interior components for
routine maintenance and service to maintain peak perfor-
mance. Special frame channels and easy-to-remove panels
or hinged access doors of the USA Indoor Air Handler cabi-
net provide complete access to the unit interior and compo-
nents. These components, including the fan and coil as-
sembly, can be removed through the side of the unit, top of
the unit, or a combination of both, which reduces required
service clearances. Coil removal on unstacked coils does
not require access to the non-connection end of the coil. A
unique coil tie down method simplifies coil removal and re-
placement. 5
