Compressed air generators which use available steam as their drive source are to be found in power stations and process plant.
The fully practice-oriented MT 142 system enables comprehensive, professional-level courses in machinery and plant maintenance to be constructed. A small, single-stage steam turbine drives the oil-injection screw-type compressor via a clutch. A combined air and oil cooler reduces the final compression temperature of the air and ensures that the oil in the screw-type compressor does not exceed the permissible operating temperature. The system includes all the necessary safety devices and the instrumentation for displaying the measured values during operation. The electrical connections, with display and operator control elements, are of industrial design.
 
Highly effective training can be achieved by assigning specific tasks to a small group of students working as a team. The diversity of possible tasks means exercises lasting several hours, or courses over a number of weeks, can be conducted. The comprehensive instructional material provides a description of all the components and of the complete system, including all drawings, and precisely sets out the assembly and maintenance operations involved.
 
The compressed air generated can be used for operational purposes by adding a compressed air drier and a receiver (both available as accessories) to the system.
