Product details

DKpro pressure controllers are maintenance-free, electronic regulators for constant and variable pressures in ventilation systems or associated rooms. They can be installed and operated in any mounting position in ventilation ducts for supply and exhaust air. The casing and control mechanism are made of galvanised sheet steel. The damper blade for pressure regulation is centrally mounted and fitted with a circumferential seal. The bearing axles 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 static or dynamic sensors, actuators with standard, high speed or spring return. Sensor and controller are mounted on mounting consoles that can be manually folded or offset when space is limited. The DKpro pressure controller is controlled and electrically connected either analogue or via MP-Bus, BACnet or Modbus. All control components enable the "Constant" and "Variable 0 - 10 V, 2 - 10 V, adjustable" operating modes. Override controls, parallel operation and sequential circuits are possible. The pressure controllers allow high accuracy with only ± 5 % to ± 10 % deviation from the actual pressure.
