Water softeners are a critical asset in many commercial and industrial water treatment programs. When not designed or operating properly, they can have significant impact on the performance of these programs and lead to increased energy, chemical, water and operational costs. Watertech’s  WTA43 line of softeners have been designed to meet the unique demands of boiler, cooling and other commercial and industrial applications. They come with support from our staff of industry experts and will be configured and tested to ensure they meet the requirements of each application. When combined with our onsite startup and maintenance programs, they will protect your facility from the harmful impacts of hard water.

These state-of-the-art systems with their advanced electronics can be incorporated in a multitude of configurations. Single through six unit configurations are available from the same electronic platform. The WTA43 is designed for complex uses, yet easy to operate and maintain. It’s “plug and play” accessories make the WTA43 a simple choice for the toughest job. No hard water bypass, separate source regeneration, and brine reclaim is all made easy. Robustly constructed, the fully assembled “stack” and piston design allows for years of reliable operation.


When combined with IQ2 electronics, the system controller operates up to six units. The system diagnostics include real-time 90-day water usage, peak flow rate, totalizer, and much more. This information is downloadable to a USB drive or viewable as live information with an Ethernet connection.With its battery backup, processor, and enclosure, information is held safe and secure. The controller’s display indicates a multitude of information at first glance including LED status indicators for online,standby, and regeneration modes.
