Motor Control Solutions for Water & Wastewater Applications
Water and wastewater facilities rely on reliable, efficient motor control to keep critical processes running smoothly. AuCom offers a full range of motor control solutions — from soft starters to variable frequency drives (VFDs) and motor protection devices — to help operators protect equipment, optimise energy use, and maintain system performance across pumps, separators, aerators, and milliscreens.
Soft starters offer valuable benefits for water and wastewater applications, including:
- Protecting equipment and maximising productivity with controlled starting and stopping
- Intelligent system control, with the ability to coordinate multiple motors and system processes
- Soft stop functionality to prevent water hammer, extending the life of pumps, pipes, valves, and headworks
- Gentle acceleration to reduce mechanical stress during start

EMX4 Soft Starter
Like its predecessor, the EMX4i Soft Starter sets new standards for soft start technology. The EMX4i is not only smaller, more powerful and packed with new control and protection features, it also introduces the gamechanging Smart Card capability. Fitting a Smart Card to the EMX4i transforms it from super smart motor controller to complete system controller. This is truly a starter for the future.
