Good reasons for invest in waste heat recover
Savings Heating in winter and cooling in summer
Increase of productivity
Reduction of energy consumption costs
Fast amortization within a few years
(4 to 6 years based on electricity tariff)
No additional personal required in control room
Safety of investment Less dependency on external sources of energy
Less dependency on constant rising energy costs
Installation without influence on the production process
Installation during line operation possible if bypass is avail
Use of standard components
SIEMENS with strong experience in power plants
Environmental protection Improvement of environmental protection
Prevention of CO2 restrictions
