APPLICATION
VAV units with airtight damper blades are usually used in special applications such as hospitals, laboratories, etc. At air temperatures below 15°C, we recommend using insulated units or insulating the unit externally.
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, with 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 the average over a large number of measuring points according to the Log-Tchebycheff method. Due to the special profile shape of the FloXact™, it can regulate from 0.7 m/s inlet speed and has a very large control range and a maximum deviation of 2% at 3xD straight flow.
- Enclosure: 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.
- Valve blade: Extruded aluminum sheets 100 mm. Airtightness class-4 according to LUKA EN-1751
- Bearings and gears: Nylon maintenance-free
- Arrangement: As standard, we supply the VAV units without control equipment or complete with Belimo controllers. Air-Concepts also assembles supplied control equipment from third parties such as Priva, Johnson Controls, EasyIO, Distech, KMC, Sauter, Siemens, Honeywell, etc
