VKpro & VKup Volume flow controllers – expanded size range

Wildeboer is expanding its range of electronic VKup and VKpro Volume flow controllers to include an extensive size range with 39 Norminal sizes.

The increase in size now enables reliable volume flow control even in very confined spaces – a significant advantage for planners, plant engineers and installers.

Extensive range and high performance

Thanks to the 16 new sizes, the VKup and VKpro can be optimally adapted to a wide variety of duct cross-sections, offering greater flexibility in project planning and implementation.

Both product series cover a wide performance range from 14 to 36,000 m³/h and support flow velocities from 2 m/s. This enables demand-based control of indoor air quality across a wide range of applications in ventilation and air conditioning systems.

In addition to standard speed drives, fast speed and spring return drives are also available for the VKpro.

High control accuracy for constant comfort

VKup and VKpro offer highly accurate volume flow control based on a predefined target volume flow (VSoll). This accuracy ensures constant maintenance of the desired room comfort – a key prerequisite for efficiency and user satisfaction in modern ventilation systems.

Seamless integration into building management systems

Another key advantage is that both controllers can be seamlessly integrated into modern building management systems. Communication takes place both analogueously and via established bus protocols such as BACnet, Modbus, KNX (VKup only) and MP-Bus, enabling centralised monitoring and control as part of building automation and thus contributing to operational safety and efficiency.

Relevance of the extension

The combination of a comprehensive range of sizes, a wide performance range, high control accuracy and modern connectivity makes the VKup Volume flow controller and VKpro Volume flow controller an attractive solution for many applications:

Planning reliability and flexibility: Precisely tailored controller selection for almost every common duct diameter.
Efficiency in operation and integration: Uniform connection via standard bus protocols.
Stable room comfort: Precise and constant volume flow control across the entire operating range.

With the expansion of the size range and technical performance features, Wildeboer underlines its claim to provide powerful and flexible volume flow control solutions for modern ventilation and air conditioning systems. The new variants of the VKup and VKpro combine planning freedom, integration capability and control quality.
