Protegra CS RO/EDI

Summary

Product Identification

The PROTEGRA CS® RO/EDI Reverse Osmosis Systems are designed for high volumes of desalinated water, producing pure water for various applications. They combine Protegra CS RO with an EDI-cell to significantly increase pure water quality. The systems feature a compact design with high-quality components and intelligent control, emphasizing cost-effectiveness and consistent pure water quality. Germ reduction is achieved through a special arrangement of the separate bed process and a related pH-value shift into the acidic range, preventing bacterial growth. The EDI-cell has a loss rate of only 10%, contributing to efficient and economical operation with low operating costs and minimal maintenance.

The systems can be equipped with additional options like different tank sizes and pressure boosting systems. They represent a core element in central water treatment plants and are used with options necessary for ring main operation. All systems include an RS 232 interface. Degassing systems are available to reduce CO₂ content in feed water, helping to maintain feed water specifications and protect the EDI-cell.

Benefits:

• Easy plug & play installation (Scope of supply includes consumables)
