A demineralisation controller with conductivity and (automatic)temperature compensation universal applicable for demineralisation installations

ES2070CA a demineralisation controller with conductivity and (automatic)temperature compensation


The ES2070CA demineralisation controller with conductivity and (automatic)temperature compensation is universal applicable for automatic monitoring and control of demineralisation installations. Universally implementable for a wide range of well known brands of control valves, pilot valves and solenoid valves like Fleck, Siata, Eurowater and Autotrol. 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.
