Variable Frequency Drives

Aquify VFD

The VLT® AQUA Drive combines deep application know-how with powerful drives technology to make your water operation easier and more efficient than ever, while saving you considerable installation and running costs.

Built to last and withstand even the harshest conditions, the VLT® AQUA Drive offers trouble-free operation of any type of water facility anywhere in the world. The combination of solid design and sophisticated software-based solutions ensure considerable energy savings and help you achieve a masterclass standard of sustainable and economic water management.

  • Assets are protected thanks to specially designed software that prevents, for example, water hammering
  • Energy efficiency is maximized as a result of the drives control algorithms and design which focus on reducing heat loss
  • High energy savings related to air conditioning are ensured due to the unique back-channel-cooling concept that transfers 90% of heat away from the room
  • Electromagnetic interference and harmonic distortion are reduced thanks to the built-in, scalable RFI filter and integrated DC link chokes
  • Perfect system integration and adaptation to the application are possible due to freely programmable warnings and alerts
  • 3–8% energy savings are achieved as a result of Automatic Energy Optimization
