Superordinated Controls

Higher-level control systems


Visualization and/or control in different versions. From simple relay technology to fully automated control operation of several fan units


Remote control by means of a SPS or an IPC
Signal transmission wireless or cable

User benefits

Energy-optimised operation, recording and storage of air parameters, simple operation and remote control, fast reactions in the event of an incident, demand-oriented use of fans

Electrical data

Standard auxiliary voltages from 24 – 240V


  • Wired remote control with selector buttons
  • Wirless (GSM) or LWL remote transmission of the signals
  • Touch display or input devices (e.g. IPC with keyboard)
  • Various bus systems: Profibus, Profinet, Modbus / TCP (Ethernet)
  • The control / regulation can process simple links, individual signals from measuring devices or highly complex signal chains and dependencies according to customer requirements
  • The Korfmann air technology “Airguard” as well as the different measuring systems can be integrated into a superordinate
    control system can be integrated

Technical design (Europe) according to

EMC Directive 2004/108/EEC
Low Voltage Directive 2006/95/EC
WEEE Directive 2002/96/EC


  • Displays in different sizes, Touch Display
  • Programming (e.g.) Siemens, B&R, Alan Bradley etc.
  • Depending on the degree of automation and design, different components are installed.
  • Optimized for the application purpose.

Korfmann Air Guard

Korfmann Air Guard
Ventilation with ducts
patented System
optimizes energy balance in real time


The following things can be achieved by an intelligent target/actual comparison:

  • Enormous energy saving
  • Detection of defects in the system
  • System development (preview into the future)
  • Limit considerations (fans + ducts)

Further advantages

  • Location-independent monitoring and control
  • Documentation of the air situation


  • Control according to various measured values
    (e.g. NOX, methane etc.)
  • Integration into superordinate systems

Intelligent control and monitoring system which consists of various measurement and control components as well as computer software (see figure).
