ABB was presenting the Abilityä Digital Powertrain at the show. The Powertrain is a single portal and reporting tool for a drives, motors, bearings and pumps.  ABB is unique in that they manufacture all the main components in the system.

Erik Arfalk showed me Fluence’s Membrane Aerated Biofilm Reactor technology. He said their products can reduce the need for blowers significantly. This low energy technology is a spirally wound self-respiring membrane submerged into the wastewater tank. Low pressure air is blown though the side of the membrane to result in simultaneous nitrification and denitrification.

Nidec Motor Corporation was at the show with their motors for blower OEMs.  Their World Motor line has been available for two years now and is a complete redesign of their legacy product from US Motors.  The new line is lighter and has new castings.  The line provides better performance and efficiency.  They have a model for each application (Hostile Duty, Corro-Duty, and 841 Plus). Nidec was also proud to show me their Commander D Series that is an integrated motor with a built-in drive.

Siemens introduced their new SINAMATICS G120X drive at the show.  This new product is a variable frequency drive for pumps, fans, and compressors/blowers. The easy to use drive comes with a high-resolution graphic color keypad and optional Wi-Fi -enabled Smart Access application for data logging and cybersecurity.  The drive comes in a specially designed cabinet that can operate in a temperature range of -4 to 140° F.
