VCD100 GRADA International



  • Installation:


  • Shape:



The VCD is an intelligent ceiling air diffuser with integrated flow rate controller for both supply and exhaust purposes. This enables autonomous flow rate modification depending on the prevailing environmental conditions, e.g. occu- pation degree, indoor air pollution and thermal loads. Thermal comfort in the occupied zone is optimized during ope- ration as the diffuser exit air velocity is better preserved at changing flow rates than with traditional diffusers. Although primarily aimed for constant-pressure duct system designs, it can be applied to other situations too.
