What We Mean By Earth•Wise

Breaking the .48 kW/Ton

Efficiency Barrier

The Trane Earth•Wise CenTraVac has a proven track record as literally the world’s most efficient, lowest emissions chiller. In fact, a portion of the product line is selectable at an unmatched efficiency level of .48 kW/ton, at standard ARI rated conditions. 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.

On 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, 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 (NPLV’s) to those of competitive units.

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 while SO2 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.

Lowest Total Refrigerant Emissions In The Industry

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.

Balancing Our Accountability for Ozone Depletion, Global Warming and Energy Efficiency

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.
