VKpro volume flow controllers are maintenance-free, electronic controllers for constant and variable volume flows in room air conditioning systems. They can be installed and operated in any position in ventilation ducts for supply and extract air. The casing and control mechanism are made of galvanised sheet steel. The blades for volume flow control are centrally mounted and fitted with a seal. The bearing shafts are made of stainless steel and are guided in special plastic bearing bushes. The measuring cross is made of aluminium.
The control components consist of a controller with integrated static or dynamic sensor and an actuator with standard, fast or spring return. The controller with integrated sensor is mounted on a mounting bracket, which can be manually edged or moved if space is limited. The VKpro volume flow controller is controlled and electrically connected in the same way, via MP-Bus®, BACnet or Modbus.
All control components enable the operating modes 'constant' and 'variable 0 - 10 V, 2 - 10 V, adjustable'. Override control, parallel operation and sequential operation are possible. Factory settings can be ordered. On-site modifications are possible with the aid of a setting device, also in combination with a PC or via the integrated NFC interface with a smartphone.
The volume flow controllers enable high accuracy with only about ± 5 % to ± 20 % deviation from the actual volume flow; accordingly, the volume flows are kept constant over the entire pressure range from 5 Pa to 1000 Pa.
