CRIUS Controller

CRIUS® Controller

Highest Quality – Low Cost – Superior Functionality

Part of a range of controllers, the CRIUS® is the big brother of the CRONOS® and offers more sensor connections, more functionality and more flexibility with a colour screen and optional built in 3G modem. The CRIUS® is an attractively priced, top of the range instrument controller. Optional communications packages allow Profibus, Modbus ASCII, Modbus RTU, Modbus TCP and others.

The CRIUS® is equipped with the capability to connect up to four sensors of any type with appropriate analogue outputs and relays. Four sensors not enough? Simply connect up to 4 CRIUS® together all using the same display and communications. Equipped with data-logging as standard and multiple PID loops as options, the CRIUS® is very able to control complex water treatment processes at a fraction of the cost of other controllers.

With all users having their own log on, and with three levels of instrument and remote access security, you can use the CRIUS® with all of its superior functionality with confidence.

A CRIUS® plus Sensor equals…

  • Free Chlorine Analyser (HaloSense)
  • Total Chlorine Monitor (HaloSense)
  • Chlorine Dioxide Analyser (DioSense)
  • Ozone Monitor (OzoSense)
  • Dissolved Oxygen Meter (OxySense)
  • Suspended Solids Monitor (SoliSense®)
  • Turbidity Meter (SoliSense®)
  • Streaming Current Monitor (StreamerSense)
  • pH Analyser (pHSense)
  • ORP Analyser (ORPSense)
  • Organics Monitor (UV254Sense)
  • Biofilm Monitor (BioSense)
  • Online Conductivity Monitor (ConductiSense)
  • Particle Counter (CounterSense)
  • Filter Monitor (FilterSense)
  • Coagulation Controller (CoagSense)
  • External inputs
  • Choose from Standard Configurations or ‘Build Your Own’

For each sensor the CRIUS® will prompt users through calibration procedures and will remind them when maintenance is due for each sensor type.

The CRIUS® is currently used in a multitude of applications including: Water Treatment for the control of, for example, Cooling Towers where the online biofilm control of the BioSense and the remote access capability is bringing solutions to our customers’ water treatment requirements.

The CRIUS® is preferred in the Swimming Pools market, where the superior control and sensor capability provides for better quality bathing water. Again the remote access is proving essential to our customers along with the Variable Speed Drive (VSD) control which is massively reducing electricity usage and CO2 emissions (and reduces the electric bills!).

In the municipal drinking water market, the superior control capability is making it the controller of choice for areas like coagulation control with the superior sensors in use particularly for chlorine control and dissolved oxygen control.

Summary of Applications

  • Water Treatment
  • Drinking Water
  • Waste Water
  • Pool and Spa Control
  • Industrial Water
  • Food and Drink
  • Paper and Pulp

The CRIUS® can also come in a multitude of languages making it suitable for use in any market.

Customers requiring a no-frills controller should consider the CRONOS® controller.
