Siemens’ new Protegra CS systems deliver Type II water for healthcare and laboratory markets

Siemens Water Technologies introduces the Protegra CS water system that combines reverse osmosis (RO) and continuous electrodeionization (CEDI) technologies to produce consistent ASTM Type II pure water quality from a soft water source.

Available in four models with flow rates from 120 to 750 liters per hour, the Protegra CS system can supply pure water to an entire building or to one laboratory with multiple points of use.

Protegra CS is ideally suited for higher flow applications, such as feeding autoclaves, glassware washers and environmental chambers. All system components are contained in a single compact cabinet with removable side panels for easy maintenance. These eco-friendly systems can be fully integrated into a central purification system or a loop make-up and delivery system. Water quality sensors throughout the system send data to an easy to read control panel display located on the front of the system cabinet.

The Protegra CS system uses high-capacity RO membrane, and is designed to remove dissolved solids from the feedwater source while sending minimal reject water to drain. The system also uses a single CEDI module that continually regenerates, eliminating the use of costly chemicals. The maintenance-free CEDI module consists of ion exchange resins and electricity to remove ions from water, resulting in a purified water quality of up to 17 megohm-cm.

The Protegra CS system combines RO and CEDI technologies to produce consistent high quality water.

Protegra CS is a trademark of Siemens and its affiliates in some countries.
