EWS RO Controller Panel OS3051/1
£1,565.00
EWS water treatment controllers are advanced technological solutions meticulously crafted to optimise the monitoring and control of water softener and filtration systems, offering versatility and reliability in various installation configurations.
The EWS OS3051/1 RO controller is a universal control panel for automatic monitoring and control of reverse osmosis plants.
The controller is equipped with a conductivity meter, optional is a second conductivity meter and temperature meter. Also optional is a circuit board with two recorder outputs (0(4) – 20 mA). There are five possible stages : “Stand by”, “Production”, “Rinse after production”, “Rinse during standby” and “Maintenance”. Adaptable to user specific requirements by built-in programmable options. The programmed configuration will be stored into non volatile memory and therefore not be affected by power loss.
