Introducing
Today’sVariTrane®
Leadership Redefined

The quality and reliability
you’ve come to expect with
Trane VAV units
just got better.

Take A Look Inside the VariTrane Unit
VariTrane – Leadership
Redefined
The Trane Company is pleased to
introduce a breakthrough in Variable Air
Volume (VAV) technology — the new
VariTrane VAV terminal unit. VariTrane
units are manufactured in the most stateof-the-art VAV facility in the world. Proven
components, such as the patented Trane
Flow Ring and theTrane DDC controller,
are used. The most advanced
manufacturing techniques in the industry
have been implemented to provide an
exceptionally rugged and reliable VAV
unit. All products are UL listed for safety
and provide proven performance via
accepted industry standards like
ARI-880 and 885.

Controls –Trane installs more
customer-supplied VAV controllers
than any other manufacturer in the
industry. For the highest quality and
reliability, demand Trane controls.

Flow Ring – The patented Trane
flow ring provides unmatched
airflow measurement accuracy and
unit performance. It is recessed
within the 18-gage air valve
cylinder for protection during
jobsite handling and installation.

All VariTrane units have the following:
— Trane flow ring for unmatched airflow
measurement accuracy
— Heavy gage air valve cylinder
— Interlocking panels which create an
extremely rugged unit
— Insulation edges are encapsulated
with metal
— UL and CUL listing
— Fusing and disconnects (optional)
— Control power transformers (optional)

Single-Duct and Dual-Duct Air Terminals:
— Single-duct reheat options include wateror electric-heating coils
— Unit sizes provide 0 to 8000
nominal cfm
— Access for water coil cleaning
— Factory-commissionedTrane controls
— Factory installation of customer
supplied controllers
— Slip and Drive connections as standard

External Shaft – Comes with Air
Valve Position Indicator for easier
service diagnostics. An external
shaft also simplifies mounting of
all brands of controllers.

Fan-powered Air Terminals:
— Parallel intermittent fan and series
continuous fan configurations
— Complete reheat options include water or
electric heating coils
— Fan sizes provide 200 to 3000
nominal cfm
— Single-speed motor with SCR is standard
for simplified system balancing
— Optional high efficiency ECM motors
— Low-height models for critical
plenum requirements

Fan Controls – Now comes with a
standard SCR used for fan-speed
control and system balancing.

Complete VAV Control Offering
All VariTrane VAV controls are factory
commissioned.This means that
airflow, temperature setpoints, and
addressing are performed in a
controlled factory environment. 100%
factory-run testing is included to
ensure that units arrive and function
properly upon job startup. With factorycommissioned controls, you have
better control over cost and quality.
This results in a higher quality
installation at a lower cost.

Air Valve – Designed to limit
inlet deformation and provide
consistent and repeatable
airflow across the flow ring.

Trane Factory-commissioned Controls
Include:
— DDC controller, the VAV Unit Control
Module (UCM) — Optimized
performance and integration toTrane
Tracer system.
— Pneumatic controller — Field
configurable for reverse- or directacting thermostats.
— Analog controller — Noncommunicating electronic control with
optional sensors.

Factory-Installation of Customerfurnished Controls:
Some customers prefer to provide
their own controller to be installed in
our manufacturing facility. In these
cases,Trane will:
— Ensure compatibility with unit relays,
fuses, and transformer
— Install the controller, including piping
the pressure transducer to theTrane
flow ring
— Coordinate with the owners preferred
control vendor

Interlocking Panels –
Ruggedness and rigidity are
assured withTrane’s patentpending interlocking panel
construction. It creates
unmatched unit rigidity.

The factory-installed controller option
has been available since the early
1990s. It provides unlimited controller
flexibility for building owners, and
should be considered whenTrane
controls are not required.

Metal Encapsulated Edges –
All VariTrane Units are complete
with encapsulated edges to arrest
cut fibers and prevent erosion in
the airstream. This raises the bar
in the VAV industry.

Complete Systems Include VariTrane Units
Integrated Comfort
Systems (ICS)

A significant consumer of energy in
commercial buildings is heating and
air conditioning. One of the most
energy-efficient HVAC solutions is the
VAV system. This has led to a steady
increase in VAV systems over the past
several years. VAV systems save
significant energy, comply with
ventilation requirements, and
provide reliable and personalized
occupant comfort.
% HVAC Energy Consumption

Trane’s Integrated Comfort System (ICS)
combines VariTrane VAV terminal unts,
Trane DDC controls, and factory
commissioning. Trane ICS enables
system-level control strategies like
Ventilation Reset and Static Pressure
Optimization to improve system
performance and efficiency. It’s like fuel
injection in a car’s engine. A gravity-fed
carburetor will provide gas to your car’s
engine, but fuel injection does it in the
most efficient manner, while boosting
horsepower. ICS is just that — a
horsepower and efficiency boost for
your VAV system!

Energy-saving features of Trane VAV
terminal units include:
— System strategies like Ventilation Reset,
and Static Pressure Optimization, etc.
— Night setback
— Occupied/unoccupied control
— Demand controlled ventilation
— Electrically Commutated Motors (ECM)
— EarthWise™ Systems utilizing low
temperature air

Doesn’t ICS increase VAV system
complexity, which may impact
reliability?
Not really. Again, most VAV systems
are already using communicating
controllers on VAV units and air
handlers. Control strategies that save
energy are pre-programmed into the
VAV controller and Trane Tracer
System, which eliminates field
programming errors and complexities.
Implementing them only requires
minimal time and it actually improves
system reliability! All Trane VAV
controllers are factory commissioned.
This means that all temperature and
airflow setpoints are downloaded and
100% run tested in the factory before
shipment.You can be assured that
Trane DDC systems are the most
reliable system available!

Summary
An integrated system is essential for
complete building environmental
comfort and system efficiency.Through
the use of factory-commissioned
controllers, and the existing
capabilities of the DDC system,
additional energy saving strategies can
be implemented. At the same time, the
system maintains the highest reliability
in the industry. Call your localTrane
Sales Office for additional details.

To determine the potential energy
savings a VAV system can bring to your
applications, The Trane Company offers
energy modeling programs like
System Analyzer™, and Trace 700™
simulation software.
