The Protegra CS® Pro RO series is the successor of the reliable and very robust Protegra CS series of the past years.
With a new design and state-of-the-art technical features, it is the frontrunner in its class - easy handling and continuously high performance.

The new features at a glance:
- 7-inch touchscreen display
- Removable side panels for easy access
- Energy-efficient VFD pump (frequency converter controlled) with longer service life for systems from 500 l/h.
- All components are designed for 24/7/365 operation
- Extended data connectivity, e.g. uninterrupted data recording (USB, microSD)
- Optional Modbus TCP gateway (W3T570885)
- Power supply: 3~/N/PE AC400V, 50/60 Hz
- Optional LED traffic light to visualize the system status
- 3 configurable changeover relays for signal routing (e.g. alarms, start release external pump)
- Available in the following flow rates (l/h): 200, 350, 500, 750, 1000 and 1200

The Protegra CS Pro RO is designed for the production of larger quantities of pure water.
The demineralization rate is at least 98%. The system can, for example, be installed as a central water treatment plant in a building and can be expanded with accessories as needed to
connect to a closed water piping circuit.
