GUNT Multivariable Control System for Stirred Tank with Digital Controllers, Heat Exchanger, Three-Way Valve, and PROFIBUS Interface

The GUNT Multivariable Control System for Stirred Tank offers hands-on training in advanced process control by simulating a typical chemical engineering application. It demonstrates the complexity of multivariable systems through the interdependence of temperature and level within a heated stirred tank reactor.

Product Features

  • Designed for practical learning of complex multivariable control systems in process engineering.
  • Model simulates a chemical reaction in a heated stirred tank using water as both reactant and product.
  • Reactant is transported from a collecting tank via pump and pre-heated in a heat exchanger before entering the stirred tank.
  • Heater in the double jacket enables temperature control within the stirred tank.
  • Heated product exits the tank and passes through the heat exchanger to transfer heat back to the incoming reactant, enhancing energy efficiency.
  • A bypass allows part of the reactant flow to avoid the heat exchanger, enabling dual-path thermal control.
  • Three-way motorised valve adjusts the ratio between pre-heated and bypassed flows to regulate tank temperature.
  • Outlet flow is adjusted using a control valve, which changes the tank level—introducing a second control variable.
  • Temperature and level are interdependent variables, forming a true multivariable control scenario.
  • Two industrial-grade digital controllers provided for temperature and level control.
  • Controllers can be configured and parameterised via included software.
  • Equipped with PROFIBUS DP interface for monitoring and communication with optional software RT 650.60.
  • RT 650.60 software enables real-time variable logging and full controller parameterisation from a PC.
  • Multiple GUNT trainers can be networked through PROFIBUS for integrated training systems.

Benefits

  • Hands-on exploration of multivariable process dynamics in a chemical reactor simulation
  • Dual temperature control via heater and flow ratio adjustment enhances process understanding
  • Digital industrial controllers and PROFIBUS integration for realistic training
  • Modular and expandable with other GUNT control systems via networked interface
  • Ideal for engineering programs focused on advanced control and process optimization
