Highest measuring accuracy
Insensitive to inflow
Reduction of the regulatory effort
Precise, energy-saving, with volume flow measurement and Active Control
The DREactive round pressure regulators keep a desired pressure constant in a room or supply air/exhaust air duct and are also used to shut off air ducts. Use e.g. in conjunction with LTG induction units. Drive and control are carried out with external energy (electrical).
- Optimum utilization of the system’s energy-saving potential by reducing the required pressures
- Reduction of the regulatory effort
- With additional volume flow measurement and ActiveControl
- Large control range for difference pressures up to 1000 Pa
- Large measuring range from 1…10 m/s
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
