CASE STUDY

Due to the integration of a variable-frequency drive unit , the booster pump is now controlled as a function of demand so that the unit uses much less energy .
consumption involved changes on the air control dampers . Moreover , the flow velocities inside the system were adapted via a modified fan control regime , resulting in substantially less vapour getting discharged . In the case of the booster pump , a variable-frequency drive unit now provides demand-based control and hence , energy savings .
Thanks to these relatively minor improvement measures the system ’ s overall electric power consumption was cut by around 30 percent . Savings of the same magnitude were achieved at the level of the water consumption , and are additionally reflected in a reduced need for cleaning chemicals .
An independently validated reference project
The measures were initially carried out on a system installed in the Steyr / Austria-based engine plant . For an objective evaluation of results , the Technical University of Vienna accompanied the reference project with extensive pre- and postoptimization measurements . Depending on the availability of national or regional programs , the unbiased attestation of this successful efficiency improvement may support applications for public funding .
The SBS Ecoclean Group ( former Dürr Ecoclean ) develops , manufactures and distributes future-oriented machines , systems and services for industrial parts cleaning and surface processing . These solutions , which are technology leaders , support companies around the world to manufacture their products efficiently and sustainably in high quality .
