AEGIS X Controller

The ultimate in water treatment control flexibility - AEGIS X

AEGIS X is an open platform water treatment controller for municipal, industrial, food and beverage, cooling and boiler treatment applications.
To optimize the water treatment process the device continuously monitors and controls a variety of measured parameters and digital inputs. Control of various devices is accomplished through the flexible programing the open platform controller. The device can control metering pumps, valves, motors, and other components to provide full automation of your system.
With up to two satellite units, AEGIS X can accommodate complicated processes. The combination of main and satellite units ensures truly excellent flexibility.
Thanks to the large number of communication options, the water treatment process can be remotely controlled with ease. An individually adaptable web server makes simple management, tracking and data visualization possible.

  • Up to two satellite units can be added for additional inputs and outputs, allowing more sensors and pumps to be connected – This provides expandability, ability to control processes with many parameters and ease of onsite installation.
  • Intuitive operation via the HMI (Human-Machine Interface) thanks to a clearly legible industrial display and robust keys for standard commands, such as calibration and monitoring. – This feature eliminates the need to replace or repair costly touch screens.
  • The adaptable web server permits simple configuration of process settings as well as monitoring and visualization of process data. This feature provides ease of programming of the controller as well as superior user experience with the ease of the web server format.
  • Extensive overview and control of the water treatment processes: All process data and alarms can be communicated to operations control system via fieldbuses such as Modbus RTU. – This feature eliminates time spent checking the process through annunciation of alarms and warnings for the process.
  • Advanced communication options: Various network protocols such as FTP or MQTT enable remote access and data management via Wi-Fi and LAN (Ethernet).
  • Advanced calculations, such as cost calculation for managing chemicals.
