RT 584

Heat Exchanger Process Control System

Technical Description

This laboratory test stand is used to explain the basic terminology of control engineering based on the practical example of a heat transfer process. It comprises a complete system that is fitted with components commonly used in industry. Water is heated in a collector tank with an immersed heater and pumped in a circuit through a heat exchanger. The second circuit is operated by a circulating pump. Heat can be dissipated from this circuit by a cooler with an electrical fan. The universal controller actuates a pneumatic flow control valve in the heater circuit. It can be set to all common configurations. In addition, it is also possible to use the controller as a cascade control system controller. Software for the process visualisation RT 584.20 and RT 650.12 Profibus card are available as an accessory.
