Operation monitoring: Ventilation box



To operate at the right time to ensure the ROI of your contracts while guaranteeing the best satisfaction of your customers and  users of buildings.



With adeunis® DELTA P, you can remotely monitor your ventilation systems (CMV – Controlled Mechanical Ventilation or AHU – Air Handling Unit).
Installed on a CMV unit or on the filter of a AHU, the DELTA P will allow you to:

  • Gather a pressure delta between your CMV unit and atmospheric pressure (periodically and/or on event: threshold override),
  • Monitor the filter fouling by observing the pressure on both sides of the filter (periodically and/or on event: threshold overide)
  • Discriminate a remote power failure by connecting a current clamp to one of the phases of your system,
  • Be warned in case of a machine failure (motor, start/stop) with the digital inputs/outputs connected to the dry or relay contacts of the machine or controller,
  • Be warned in case of failure of a pressure switch already installed on your machine.
