APPLICATION
The VAV units with integrated silencer are used in ventilation systems to improve comfort and reduce energy consumption. The insulated, double-walled housing prevents condensation from forming in cold primary air and reduces the radiated noise. The unit is controlled by a room sensor with temperature and/orCO2 or from the building management system and varies the air volume based on cooling demand and/or ventilation requirement.
This results in significant savings in fan energy because, when there is little or no cooling demand, the valve can be partially or even completely closed.
FEATURES AND BENEFITS
- Air flow sensor: the FloXact™ has a linear gain factor of at least 2.5x, and measures over 6, 8 or 10 measuring points according to the Log-Tchebycheff method. These units do not require straight flow and can accurately control from 0.4 m/s inlet speed.
- Housing: Magnelis steel (S235+ZM310). This steel with a modern surface treatment with a very high corrosion resistance. It is less harmful to the environment and has a beautiful appearance (comparable to anodized aluminum). Airtightness Class-D according to LUKA and EN-1751.
- Insulation: 50mm mineral wool with Magnelis steel cover
- Valve blade: sandwich construction, 1.5mm SBR sheet rubber with inlay between 2 Magnelis steel blades. Airtightness class-3 according to EN-1751.
- Controller: As standard, we supply the VAV units without control equipment or complete with Belimo controllers. Air-Concepts also installs supplied control equipment from third parties such as Priva, Johnson Controls, EasyIO, Distech, KMC, Sauter, Siemens, Honeywell, etc.
