The flexible filter for central/decentral harmonic mitigation
The VLT® Advanced Active Filter AAF 006 improves system efficiency and increases grid robustness to avoid downtime. It can compensate for individual drives or it can be installed as a compact standalone solution at a point of common coupling to compensate for several loads simultaneously.
The active filter ensures optimal harmonic suppression independent of the number of loads and their individual load profile. In addition, it corrects the power factor and balances the phase load to provide optimal energy utilization.

A range of applications for the water and wastewater, marine, oil and gas and mining industries.
Drives for compressors in residential buildings
Variable speed control of a chiller allows you to provide constant pressure regulation while matching the capacity to the actual need based on measurements in the system. Speed control is beneficial when a compressor runs for long periods at partial load. Reduce operational costs by running applications at a lower speed which reduces energy consumption. And reduce installation costs by optimizing the system and the compressor itself.
