SGT 400s
Please find attached pics and description of the SGT 400s
The SGT 400 combines very high efficiency (nominal 35 %) with excellent emissions
Performance in a rugged industrial design.
This makes it the ideal choice for a wide variety of power generation applications.
The Siemens twin-shaft industrial gas turbine SGT-400 features a compact gas
generator and a two-stage power turbine, Incorporating the latest aerodynamic and
Combustion technologies.
2. Equipment Description and Scope
The gas turbines are designed to operate on natural gas.
There are 7 units of the SGT 400 year 2014 free to take any quantity the want.
Price is US$ 4,955,000 Each.
If 3 or above are taken there will definitely be a reduction in price.
These have an average of 5000 Hours each.
Still standing so inspection will not be a problem.
