DRpro pressure controller
DRpro electronic pressure controllers regulate the static pressure in ventilation and air conditioning systems. The specified pressures are kept constant against a reference pressure or variable pressures are regulated. They can be used in any position and, thanks to their short pipe length, even in confined spaces. They use differential pressure to regulate with maximum accuracy and minimal flow noise.
Technical details
- For constant and variable differential pressures
- Position-independent installation
- Bus-compatible controllers with integrated static or dynamic sensor
- Easy installation in confined spaces thanks to short pipe length
- Optionally prepared for insulation on site
Declarations & proofs
Product details
DRpro electronic pressure controllers regulate the static pressure in ducts of ventilation and air conditioning systems or in associated rooms, both in supply air and exhaust air applications. They maintain the specified pressures constant against a reference pressure or regulate variable pressures.
They are maintenance-free, operate in any position, and feature a short pipe length, which facilitates installation in confined spaces.
The casing and brackets are made of galvanized sheet steel. The flap blade for pressure regulation is centrally mounted and equipped with a circumferential seal.
The bearing axes are made of stainless steel and are guided in special bearing bushes. The measuring cross is made of aluminum and can be used to connect a volume flow measuring device.
Leak tightness classes
The pipe housing has a leak tightness class C according to DIN EN 1751, and the damper blade reliably shuts off the air duct in classes 3 or 4, depending on the size, if required.
Control accuracy DRpro
The DRpro pressure controllers regulate with very high accuracy of only approx. ± 5 % to ± 10 % deviation from the actual pressure.
Bus-compatible control components and actuators
Bus-compatible control components simplify system planning. The actuators are also available with special functions, and their wide range of mounting options ensure a high degree of flexibility for demanding applications.
The control and electrical connection of the DRpro pressure controller are analog or via MP-Bus®, BACnet or Modbus.
The control components consist of static or dynamic sensors, actuators with standard, fast or spring return operations, and a controller. The sensor and controller are a single building element mounted on a bracket that can be manually tilted or offset to accommodate tight installation conditions.
