Fouling: control the ventilation filter



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.
