Hermetic Centrifugal Water

A Tradition of Innovation
The first Trane centrifugal chiller,
the Turbovac™ , became the industry leader upon its introduction in 1938. The simple, compact 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. The 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 compact model PCV CenTraVac
chiller, 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.
The addition of microprocessor
controls in 1985 proved once more that Trane was committed to keeping the CenTraVac chiller at the leading edge of technology.
A History of Reliability
The basic design first used in the
Trane Turbovac remains. 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.
The Trane commitment to innovation,
quality and reliability for our customers will help ensure our leadership for years to come.
The Value of Quality
Customer satisfaction with the
performance and reliability of the Trane CenTraVac chiller has earned it its status as the best selling centrifugal chiller
on the market. The value of the CenTraVac chiller is in
its simple design and unsurpassed reliability.
The Trane quality process helps to
ensure that our chillers are engineered to meet our customer’s requirements in all important areas. The Trane approach
to problem solving finds the root cause and corrects
it. The result is a simple, reliable chiller dedicated
to serving the customer’s chilled water needs for years to come.
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 being developed 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.
