Trane’s state-of-the-art manufacturing
facility employs a system of checks and
verifications at each work station to
ensure consistent quality.
As T-Series Climate Changer air handlers roll
down the production line, one would be hard-
pressed to find any two alike, indicative of how
flexible a “cataloged” air handler can truly be.
The T-Series air handler, with its
modular design, is very adaptable in
meeting the market’s ever-changing
needs. Trane understands that some
projects call for an air handler that
incorporates new, emerging technolo-
gies or a job-specific requirement.
Trane’s experienced team of profes-
sionals can tailor the T-Series air han-
dler to meet these requirements—
with proven, tested performance.
These factory-packaged specials
deliver Trane quality, enable simplified
on-site installation and startup, and
are usually more cost effective than a
fully custom-built unit.
Some of the popular, emerging
technologies and custom features
that Trane can incorporate into the

An outdoor central-station air
handler must move and condition air,
maintain high air quality standards, and
withstand the elements. Extreme
temperature changes, humidity levels,
salt air, high winds and indoor air quali-
ty standards were all taken into consid-
eration when Trane engineered the
T-Series air handler. Some of the
design elements of the T-Series air
handler that ensure a reliable product
throughout its life are:
■ A sloped roof with overhang
promotes complete drainage and
directs water away from the top of
the access doors.
■ All unit joints are sealed and fas-
tened with a galvanized steel joint
strip to improve unit integrity.
■ Formulated, double-wall panels
with rigid, closed-cell foam insula-
tion mean fewer seams and no
moisture absorption.
In addition to keeping water out,
T-Series air handlers are designed
to provide extraordinary insulating
capabilities for efficient and cost-
effective performance.
■ Standard double-wall panels with
two-inch closed-cell insulation pro-
vide a minimum R-value of 12.
■ Panels include internal and
external gasketing for a
proper thermal break.
■ Energy recovery
options help meet
ventilation requirements
while lowering energy costs.
Contributing both to water resistance
and thermal performance is the innova-
tive T-Series air handler door and latch
design, which offers distinct advan-
tages over traditional air handler doors.
■ Double-wall doors with a single
handle allow for easier access for
maintenance and cleaning, while
ensuring a positive seal across the
entire door frame.
■ The door latch is surface mounted
instead of piercing the door,
eliminating the possibility of water
entry and improving the thermal
performance of the
door.

Formulated double-wall panels with rigid
closed-cell foam insulation provide unsurpassed
panel strength and deflection resistance.
All Trane factory-mounted controls are engineered,
installed and tested by experienced technicians
before leaving the factory. This ensures an easy,
trouble-free installation, fast system start-up and
rapid building commissioning.
The T-Series Climate Changer air
handler provides one of the most
comprehensive factory-packaged
controls systems available. This
simplifies job-site coordination, saves
installation time, reduces expenses
and minimizes risks.
■ Trane provides a full range of
controls and end devices, including
starters, variable-frequency drives,
disconnects, control valves,
sensors and switches.
■ Factory mounting assures
correct and properly sized
control components.
■ Components are computer-tested
to simulate actual operating
conditions.
The T-Series air handler turnkey
control package can be used in a
stand-alone operation, or it can be
fully integrated into a comprehensive
control system. Trane’s Integrated
Comfort system (ICS) incorporates
the benefits of factory-installed con-
trols and links the air handler to the
Tracer Summit™ building manage-
ment system. For owners, facility
managers, designers and contractors,
ICS means:
■ System optimization through
system-wide information sharing.
This enables maximum operating
efficiency for each building subsys-
tem, resulting in reduced building
energy consumption.
■ The ability to tie in to existing
equipment and systems. End
devices can be wired to terminal
strips for a generic field interface to
DDC controllers. Also, BACnet,
ASHRAE's industry standard open
protocol, allows full two-way
communication.
■ Single-source responsibility for
warranty and service.
The T-Series air handler was engi-
neered to address the complex
issues of indoor air quality (IAQ).
Building owners must give particular
attention to maintaining and docu-
menting IAQ to ensure tenant
comfort and to meet industry and
government regulatory standards.
■ A standard T-Series option, the
patented Traq™ damper airflow
monitoring station, can be coupled
with a Tracer building manage-
ment system to monitor, control
and document ventilation airflow
in compliance with ASHRAE
Standard 62 guidelines.
■ ICS provides comprehensive
monitoring and diagnostic capabili-
ties—a powerful tool for schedul-
ing preventative maintenance and
reducing equipment downtime
and service expense.

Electrical usage of mechanical
systems in commercial buildings is
typically about 50 percent for light-
ing, 25 percent for the “waterside”
of the comfort system (chillers, cool-
ing towers and pumps) and 25 per-
cent for the building’s air dis-
tribution system. Delivering
conditioned air and water
throughout the building
carries a considerable cost
impact.
Therefore, reducing the amount
of air and water circulated through
an HVAC system should decrease
operating costs—significantly. This is
mainly because the relationship of
flow to the amount of power
consumed to achieve that flow is
not proportional.
■ The airflow rate (cfm) required is
dependent on the leaving air
temperature of the air handler.
■ The component and system
pressure drop has a squared
relationship (x2) to the flow rate.
■ The power required to move the
air and water varies with the cube
(x3) of the flow rate.
What this all means is that a decrease
in the airflow temperature delivered
to a building, delivered at a lower
flow rate, ensures occupant comfort
while decreasing costs. Example:
Looking at both first cost and life
cycle costs, the savings are dramatic.
In addition to the obvious energy sav-
ings, moving less air reduces the
physical size of air handlers and duct-
work, which can result in quieter,
smaller mechanical equipment rooms,
plenums and duct chases. This means
lower first costs and less space used
for the comfort system infrastructure
leaving more room for occupants and
your business.
Although low temperature, low flow
systems can challenge conventional
outdoor air-handling units, the
T-Series Climate Changer air handler
is designed to optimize systems like
EarthWise.
■ The insulation integrity of the
T-Series air handler is key in
maintaining system efficiency by
reducing cabinet heat gain and
minimizing troublesome conden-
sation on cabinet surfaces.
Foamed, double-wall panels
standard on T-Series air handlers
are superior to traditional double-
wall systems due to their inherent
airtightness.
■ An almost infinite coil selection
allows heat transfer and air pres
sure drop performance to be tuned

Distinguishing characteristics of the EarthWise sys-
tem are low flowrate and low temperature for the
water and air distribution elements of the system,
along with high efficiency equipment. This design
philosophy reduces HVAC system first cost, lowers
operating cost and is right for the environment.
