Environmental Return on Investment*

7,398 tons of CO2e savings in 5years of operation(not released to the atmosphere)

*This is a demonstration only. Real values will

depend on a specific evaluation of the application/sitein question

In this example, it was used the CO2 generation for the state ofTennessee based on the National Renewable Energy Laboratoryreport on Source Energy and Emission Factors for Energy Use

in Buildings (dated June 2007).

The applicable state/country information must be customized foreach case.

Average kWh produced 275 kWhCO2e generation (per kWh from utility company) 0.90 kgs/kWh

Displaced Electricity CO2e 1990 tons/yr

Microsteam CO2e generation 0.232 kgs/kWh

Do I have a steam pressure reduction station?

Do I have a steam flow of 4,000 lbs/hr of steam or more?

Do I pay more than $0.05/kWh for the electricity?

Do I have annual energy reduction goals?

Do I need to reduce my carbon footprint? Do I intend to obtain LEED certification?

How do I know it is right for me


27/29

Applicable for applications where steam is being pressure reduced

Unique opportunity for wasted steam pressure energy

Savings opportunity for small steam systems: municipal and industrial

Compact, robust and simple installation

Justifiable economically and environmentally

LEED points enabler
