Introduction
The first Trane centrifugal chiller, the
Turbovac
™
was introduced in 1938. The
simple, direct drive, slow speed design
of the Turbovac revolutionized the air
conditioning industry. The chiller was
attractive to customers because its
hermetic design reduced frequent
service requirements.
In 1951 the Trane CenTraVac
™
centrifugal
chiller was introduced. Its unique two
stage compressor with multiple inlet
guide vanes and patented economizer
reduced energy consumption on typical
applications to less than 0.8 kW/ton.
The model PCV CenTraVac chiller that
was introduced in 1966, allowed quality
air conditioning for applications as small
as 120 tons.
In 1982 the CenTraVac chiller solidified
its position as the industry leader by
introducing a three-stage compressor
and a two-stage economizer. As a result,
this chiller was 5 to 20 percent more
efficient than previous designs.
Today’s CenTraVac chiller still relies on
the dependability of the proven direct
drive and exclusive slow speed
operation. Low operating costs and high
reliability continue to be the CenTraVac
chiller hallmark.
When a source of energy other than
electricity is required
The Trane CenTraVac has the standard
option of being coupled to a Waukesha
Enginator to quite simply convert
natural gas to chilled water. With COPs
in the range of 1.5 to 2.2 depending on
options selected, makes this option a
very simple and attractive alternative
when an alternative fuel source is
desired.

Unmatched Expertise
The performance and reliability of a
CenTraVac
™
chiller is backed by a team
of experienced field sales engineers with
support from headquarters experts. No
other manufacturer can offer that degree
of support to its customers.
In the design phase, application
engineers can help answer your
questions or solve your problems.
During the selection phase, software
engineers are available to help you
evaluate equipment alternatives. At the
installation stage, field start-up of the
CenTraVac chiller is included in the
purchase price. Trane offers this support
and more when you need it.
Delivery And Design Flexibility
If delivery time is a priority, Trane can
meet your needs with a variety of quick
shipment choices. Most fast track
building schedules can be met with one
of these choices.
Design flexibility means Trane can
custom build a unit to specific job
requirements. Design parameters such
as shell type, compressor, kW/ton,
waterside pressure drop, as well as full
and part load performance can be built
to meet requirements.

ISO 9001 Certification
ISO 9001 Certification applies to the
Trane La Crosse Business Unit. This
process is based on the La Crosse
Business Unit’s ISO 9001 certified quality
system. This system is documented in
procedures which define how quality
assurance activities are managed,
performed, and continuously monitored.
Included in the system are verification
checkpoints from the time the order is
entered until final shipment. In addition,
product development for the
marketplace is subjected to formal
planning, review and validation. The
system is designed to assure maximum
consistency in meeting customer
requirements.
The Beauty of Simplicity
The reliability of a centrifugal chiller
starts with its basic product design. At
Trane we’ve found that the straightest
path to reliability is simplicity. Years of
research and field testing have honed
the design of the CenTraVac chiller to a
simple, precise solution to a complex
engineering problem.
This simple design provides efficiency
and reliability benefits. The Trane
CenTraVac chiller has only one moving
part — no gear boxes, couplings or extra
shafts. The single rotating shaft is
supported by two aircraft turbine grade/
rated bearings. This direct drive concept
minimizes the chance of failure for
moving parts. It also reduces wear and
drag on parts, resulting in more efficient
operation.
