Highest control accuracy
Energy efficient
Very short design
Unique and ingenious: LTG map control.
The VREactive volume flow controllers regulate a constant or variable volume flow in round air ducts of Comfort Air Technology systems independently of the upstream pressure.
A full barrier is also possible.
For dynamic (VRactive) and static (VRactive-s) measurement.
Actuation and control are electrical (with external power).
The housing has push-in ends with lip seals suitable for air ducts to DIN EN 1506 or DIN EN 13180.
- 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 hospitals
