50DF Modu-Pac® |
M odu-Pac®
the uncomplicated way to air condition
your building for today . . . and tomorrow!
Modu-Pac is Carrier’s packaged cooling and air distri­
bution system for variable volume, constant temperature
applications. The self-contained 50DF rooftop unit, in 5
popular sizes, supplies the cooling. The air is distributed
by Carrier’s Moduline® or Modubox variable volume
terminals, with airflows from 15 thru 400 cfm. Together they
form Modu-Pac, the air conditioning system that allows
your building to change with the times, whenever interior
layouts are updated or modified.
The secret to Modu-Pac’s unparalleled flexibility is the
Moduline terminals which leave all your design options
open. A single thermostat and volume regulator, located in
one of the air terminals, can be used to control the variable
supply air quantity individually or in a series of air terminals.
When interior partitioning changes, you’ll see how adapt­
able this air conditioning system really is. There’ll be a
minimum of changes needed... terminals, ductwork or
thermostats.
Modu-Pac serves any building... schools, offices,
libraries, shopping centers... new construction or renova­
tion. Just set the packaged cooling unit on its accessory roof
curb, attach the ductwork and install the self-contained
Moduline terminals. Get the performance you expect from
a built-up system without the extra costs of designing and
installing one. Modu-Pac does it all.
And the Moduline terminals are suitable for any type of
ceiling.. .T-bar, concealed spline, metal pan, wet plaster,
hardboard. Save on ductwork expenses, too, since the
plenum of each terminal is a part of the duct system.
With Modu-Pac, the building starts paying for itself
sooner. Added income is possible because the self-balancing
Moduline terminals permit quicker individual occupancy.
Tenants can move in weeks, even months, ahead of con­
ventional schedules. There’s no need to balance the entire
system after the building interior is completed.
Whatever your cooling needs, Modu-Pac’s unique system
approach handles them with ease. Today. Five years from
now. Or whenever interior layouts are changed.
The simplicity of rooftop, packaged air condi­
tioners brings reduced design time and low
installation costs to Moduline systems.
With a packaged system, there’s no need to put design
time into selecting various components of a split system.
Just select the appropriately sized rooftop unit. You know
the components are compatible... you know they’ve been
thoroughly tested... there’s no guesswork. And when you
see how smoothly installation goes, you know you made the
right move. A trouble-free installation saves money from
start to finish.
Jobsite expenses are minimized
The full perimeter roof curb eliminates costly steel support
frames and permits a low silhouette which often eliminates
the need for expensive parapets. The National Roofing
Contractors Association (NRCA) approved curb is installed
and made watertight by the roofer... before the unit is
installed. All ductwork, utility and condensate connections
enter the unit within the curb.
