lnspection Unit for Industry


IUI 3parts

Knowledge of industrial components plays an important role in the training of industrial inspectors. In order to acquire this knowledge it is very helpful to practice on plants with components in real scale.


The demonstration unit consists of three parts: a thermal reactor, a steam driven auxiliary pump and a compressed air station. All of these parts are connected via pipes and valves. A variety of electrical components such as cables, switches, contactors, displays, fuses and a switch cabinet show typical electrical cabling as in a real-world plant. 



Part1 reactor

Part 1: Thermal reactor with chemical injection system

This section shows an example of a thermal process. Two feed materials A, B (liquid) are pumped by two centrifugal pumps to a static mixer. The mixed feed material then flows through a first heat exchanger. In the subsequent steam-heated heat exchanger, the feed material is brought to its final reaction temperature. The heated feed material is then mixed with component C. This is done via a chemical injection system. The mixture enters reactor from below. The finished product E leaves the reactor at the upper end and transfers part of its heat to the feed material in the first heat exchanger. A dry cooling tower then finally cools down the product. The product is then stored in an intermediate tank.

Part2 pump

Part 2: Steam-driven auxiliary pump station

This part of the plant shows a steam-driven auxiliary pump. These pumps are used in industry as backup systems. In the event of a malfunction, e.g. power failure, the backup pump conveys important liquids such as coolants or lubricants, thereby protecting other components from damage. For this purpose, these components run purely mechanically and do not need electricity.


The pump station consists of an industrial steam turbine and a directly driven centrifugal pump.

Part3 compressor

Part 3: Compressed air station

This part of the plant shows a compressed air supply station. It essentially consists of two identical compressors, a horizontal pressure tank and a compressed air dryer.




Learning objectives


The following learning objectives can be achieved when working with the training plant:
