Actuators for air volume controllers

Actuators for Air Volume Controllers

OpenAir air volume controllers work with the highest degree of accuracy and stability. This is ensured not only by highly precise differential pressure measurement, but also by the intelligent software algorithms of the products. The air volume controllers provide the best conditions for highly comfortable usability.

The air volume controllers allow fast, simple parameterization. For VAV box adjustment, usually only three OEM-specific device characteristics have to be entered.

The new OpenAir air volume controllers with bus communication (KNX S-/LTE-mode and Desigo PL-Link) support efficient optimization of energy consumption in Synco 700 and Desigo systems.

 

Highlights at a glance

  • High level of accuracy thanks to fast and location-independent measured value acquisition

  • Long-term stability without aging and temperature drift

  • Fast commissioning through simple adjustment to VAV boxes

  • Increased flexibility thanks to adaptive function for rotation angles

  • Support of modern energy efficiency functions



Typical use

  • Supply air control

  • Extract air control

  • Supply / extract air cascade control
    - ratio control 1:1
    - ratio control (positive/negative pressure)
    - differential (positive/negative pressure)
