ES2070 CA

Summary

Product identification

• Unit Type: ES2070 CA
• Description: Controller for Demineralisation

Description

The ES2070 CA is a universal controller for automatic monitoring and control of demineralisation plants. It can monitor conductivity, temperature, and several inputs, such as level switches, wait signals, and external regeneration start. Programmable options allow adaptation to user-specific requirements. The programmed configuration is stored in non-volatile memory, unaffected by power loss.
