Energy analysis of an industrial company
Customer: Industrial enterprise in Graz
Period: 2007 – 2008
The analysed industrial enterprise in the area of Graz/Austria has a high process-related demand for cooling power. Furthermore during summer an additional cooling power is required for air conditioning of company-owned buildings. Additional difficulties in fulfilling the heating and cooling demand arise due to certain given boundary conditions of the nearby water stream.
Tank cleaning facility Graz
Customer: entsorgt! Abfall verwertungs GmbH
Period: 2002 - 2004
Preliminary Design and submission project (according to Trade Regulation Act) for interior tank and exterior truck wash center Graz. Only a few tank cleaning facilities exist in Austria which are capable to clean different transportation goods. Even nowadays tanks are cleaned manually only by means of a high-pressure cleaner, usually the waste water is discharged into the next sewer inlet.
In Graz/Austria a state of the art, but still affordable solution was established, thus these “backyard” techniques come to an end. In a very close cooperation with the authority, especially with the waste water department a save and trend setting solution was developed.
