Pressure regulator | DRE active

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
