Protegra CS PRO RO EDI 250
Reverse Osmosis system with Ionpure EDI, 250 l/h

CONSISTENTLY HIGH WATER QUALITY
The Protegra CS® Pro RO EDI system is a high-performance purification solution for deionised water applications. Featuring industry-leading reverse osmosis technology and a high-performance Ionpure® CEDI cell, the system maintains water quality at the required standard.
The system is ideal for a range of laboratory and industrial applications with a typical water quality of > 0,07µS/cm and flow rates up to 250 l/h at 15°C.

Product features and benefits:
- Energy efficient and high performance reverse osmosis (RO) modules effectively achieve high inorganic retention and permeate production. This reduces energy demand and
minimizes water waste.
- Electro-deionization removes the residual salt content from the water without exhausting itself.
- Automatic rinsing of entire system before going into stand-by mode reduces build-up of ions in the RO membranes - increasing the lifespan.
- Microprocessor control provides automatic operation with continuous monitoring of all important parameters
- The limits for conductivity and flow rates of pure water can be set individually.
- Removable front and side panels for easy service access
- The system is low maintenance.
