Totally Integrated Control System


To ensure that all processes and water quality parameters remain stable, a reliable monitoring and control system is needed. KUBE®hatch has an integrated system for optimal quality assurance in which all system information is transmitted to a PLC system. The PLC is connected to a touch screen in vicinity of the hatchery for daily operations.

The PLC controls the frequency converters and adjusts the pumping rate according to the requirements. The touch screen are able of performing databased logging and presentation of:

  • The oxygen level, pH, and temperature before and after the hatching units.
  • The flow to the bioreactor and before the hatching units.
  • TGS (Total Gas Saturation) before the hatching units.
  • The water level in the mechanical sieve and the buffer tank.


When the PLC detects errors in the system an alarm goes off that can be sent to a control system in the facility. It is possible to operate the system from PC, MAC, tablets, iPad or mobile phones. It is also possible to install equipment for full remote assistance via internet.


Back-up system

In case of an electrical breakdown, the PLC, touchscreen, instruments and alarms will be powered from an UPS with a battery bank so that the monitoring and control is feasible until the power supply is back.

All PLC units are type approved by DNV to ensure the best possible reliability
