Wildeboer Pressure Controller

 

 

Pressure controllers from Wildeboer

Pressure controllers are used for the precise control of duct or room pressure and air distribution in ventilation and air-conditioning systems (VAC). In pressure control, the static pressure in a ventilation duct is measured and maintained at a constant level relative to a specified reference pressure, or variable pressures are regulated to a setpoint. Unlike in volume flow control, the controlled variable is therefore the pressure itself.

Wildeboer pressure controllers enable this form of regulation of air flow in ventilation networks – with high control accuracy and the ability to completely shut off an air duct. This creates very stable conditions within the network, whilst at the same time reducing the control requirements of downstream air flow controllers.

Volume flow control and pressure control can also be combined to finely tune the supply air and extract air to each other. The different control variables of Wildeboer volume flow controllers and Wildeboer pressure controllers prevent the system from oscillating and make a decisive contribution to the energy-efficient operation of the system.

Wildeboer pressure controllers: the benefits

  • Highest control accuracy with low flow noise
  • Maintenance-free and can be installed in any position
  • Flow-optimised casing geometry for minimal pressure losses
  • Integrated shut-off function for the air duct
  • For constant and variable differential pressures
  • Can be combined with volume flow controllers – for energy-efficient system operation

A comparison of the Wildeboer DKpro and DRpro pressure controllers

The basis of any pressure control system is reliable pressure measurement. Appropriately selected sensors measure the line pressure and reference pressure; Wildeboer’s pressure controllers evaluate the differential pressure and use this to continuously regulate the line pressure against the reference value.

Wildeboer offers two options: the DKpro and DRpro pressure controllers. Both units are electronic differential pressure controllers and regulate the static pressure in ventilation and air-conditioning systems with the highest precision. The main difference lies in the installation: whilst the square DKpro pressure controller ensures minimal pressure losses thanks to its flow-optimised housing geometry and flow-optimised vanes, the round DRpro pressure controller stands out due to its short pipe length. Thanks to their compact design, both products are suitable for installation in confined spaces.

Optimised air distribution with an air volume and pressure control module

The BS2-VR-01 flow and pressure control modules enable the connection of up to four electronic flow and/or pressure controllers. This allows for a significant improvement in the energy efficiency and operating costs of a ventilation and air-conditioning system. You can also easily implement relevant control functions using the Wildeboer-Net software as part of a building management system.

Pressure control with Wildeboer – your specialist in air distribution

Whether dealing with constant or variable differential pressures, individual controllers or a networked system via the BS2-VR-01 module: with Wildeboer’s pressure controllers, you can control your air distribution precisely and energy-efficiently. Pressure control reaches its full potential when used in conjunction with other components: when combined with Wildeboer’s electronic airflow controllers, pressure controllers stabilise the entire ventilation network and reduce the control requirements of downstream units.

Frequently Asked Questions about Pressure Controllers

A pressure controller is used to regulate duct or room pressure and air distribution in HVAC systems. Unlike in flow rate control, it is not the flow rate that is used as the controlled variable, but rather the measured duct pressure. This is maintained at a constant level relative to a specified reference pressure, or variable pressures are regulated to a setpoint.
 

Wildeboer pressure controllers enable precise pressure control in ventilation ducts. The advantages listed on the page include high control accuracy, the ability to shut off an air duct, and the combination of pressure control and volume flow control.

Maintaining a constant pressure in the ventilation duct reduces the control requirements of downstream volume flow regulators. As a result, pressure control can contribute to the energy-efficient operation of ventilation and air-conditioning systems.

Pressure controllers and volume flow controllers operate on the basis of different control variables. Whilst volume flow controllers regulate the air flow rate, pressure controllers are based on the duct pressure. Because of these different control variables, both methods can be usefully combined in ventilation systems and prevent the system from overshooting.
