Minimum length – maximum accuracy.
The VRFactive volume flow controllers are used to control a constant or variable volume flow in rectangular air ducts of Comfort Air Technology systems, up to full shut-off, regardless of the inlet pressure. Available with dynamic (VRFactive) and static (VRFactive-s) measuring principle. Activation and control are carried out with external energy (electrical).
The housing cross-sections match the recommended edge lengths for rectangular air ducts in accordance with DIN EN 1505. This makes it possible to select the largest possible flow cross-section even in cramped installation conditions.
The housing has flanges with slotted holes, with cage nuts for the insulated version.
- Highest control accuracy of all known controllers in the low air velocity range due to differential pressure amplification
- Energy-efficient – minimal pressure loss due to small differential pressure element
- Very short design, insensitive to inflow, simple integration
- Optimized construction with particularly high airtightness
- Also with static differential pressure measurement – suitable for laboratories and hospital
Powerful effect: LTG ActiveControl map measurement
- Highest measuring accuracy of all known systems in the low air velocity range.
- Combines extremely short installation lengths with maximum control accuracy in the low air velocity range
- Insensitive to incident flow due to optimized air routing to the measuring element
- Max. 5 % deviation for Vnenn
