Pressure regulator | DRE

Reduction of the regulatory effort
Optimum exploitation of energy-saving potential

The round DRE 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.

They are also suitable for use in polluted or chemically contaminated air.
The static pressure in the duct or in the room is measured. The setpoint specification is compared with the actual value of the measuring point and the control damper is controlled accordingly until the desired setpoint is reached. Activation and control are carried out with external energy (electrical).
Use e.g. in conjunction with induction devices.
The housing has push-in ends with lip seals suitable for air ducts to DIN EN 1506 or EN 13180.

  • Optimum utilization of the system’s energy-saving potential by reducing the required pressures
  • Reduction of the regulatory effort
  • Combination with high-speed drives possible
  • Optionally with additional volume flow measurement
  • Available with dynamic (DRE) or static measuring principle (DRE-s)
