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.

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.
