Duplex Softener GM-DWS

Continuous soft water supply with zero downtime operation

Product Overview

Our Duplex Water Softener (GM-DWS) is designed for applications requiring uninterrupted soft water supply. The twin-vessel configuration ensures one unit is always online while the other regenerates.

Using premium grade strong acid cation exchange resin, the system effectively removes calcium and magnesium ions responsible for water hardness, replacing them with sodium ions through ion exchange process.

With PLC-based automation, the system automatically switches between vessels and initiates regeneration cycles based on volume treated or time elapsed, ensuring consistent output quality without operator intervention.
