| Features and Benefits Trane Earth•Wise ™ CenTraVac® Chiller Breaks
the .48 kW/Ton Efficiency Barrier
The World’s Most Efficient, Lowest Emissions Chiller
The Trane Earth•Wise CenTraVac has a proven track record as literally the world’s most efficient, lowest emissions
chiller. However, with this announcement that
leadership grows. In 1998 a significant portion of the
product line will be selectable at an unmatched efficiency level of .48 kW/ ton, at standard ARI rated conditions. And
this builds on the successful 1997 introduction of .49
kW/ton across the entire product line, from 300 to
nearly 2500 tons.
This is an efficiency level of 16 to 25 percent better than competitive chillers using other alternative refrigerants, which
are typically in the .56 to .60 kW/ ton range. And, at
part-load conditions, the kW/ton ratings are even
better; a fact that can be seen by comparing Trane’s ARI certified applied part load values (APLV’s) to those of competitive units.
Business-Wise . . .
For a 1000-ton chiller, this efficiency difference can provide savings of over $24,000 per year or nearly three quarters of a
million dollars over the life of the machine . . .
typically more than twice the initial cost of the
machine.
And Earth•Wise
The development of the .48 kW/ton chiller also has a positive environmental
impact. Consider this: If every centrifugal chiller in
the world were able to operate at .48 vs .56 kW/
ton, utility generated greenhouse gas emissions could be reduced annually by nearly 17 billion pounds of CO2 and NOx
could be reduced by over 64 and 27 billion grams,
respectively. This reduction is equivalent to removing
more than two million cars from the road or to planting nearly 500 million trees
each year.
Furthermore, the Trane "near zero" emissions Earth•Wise chiller also has the lowest total refrigerant emissions in the
industry. So low that it’s essentially a closed
system.
The key to the industry’s highest energy efficiency and lowest leak rate is the use of a low pressure refrigerant DuPont
calls SUVA-123; a refrigerant that has the lowest
direct-effect global warming potential and the highest
thermodynamic efficiency of all non- CFC refrigerants; a refrigerant in use in more
new centrifugals today than all other alternatives
combined.
The Future Is In The Balance
Reduced power plant emissions and the industry’s lowest refrigerant emission
rate put the Trane .48 kW/ton Earth•Wise
centrifugal chiller in a class by itself, from both a
business and an environmental standpoint. The future
lies in the prudent balance that takes into account the importance of ozone depletion, global warming and energy efficiency.
A balance that is right for both business and the
environment.
