Impregnation Systems

In electrical engineering, impregnation means the application of an additional insulating layer to the coil windings of, for example, electric motors, generators, transformers or sensors to increase the resistance of the winding materials under different operating conditions.

For this purpose we offer individually dimensioned and equipped impregnation plants according to the requirements of the operator, the dimensions of the components and the properties of the impregnating agents.

The variants and equipment options include

  • compact impregnation systems
  • vacuum and vacuum-pressure impregnation systems of all types and for all impregnating agents
  • vacuum drying and impregnation systems
  • atmospheric impregnation systems
  • oil impregnation systems

The choice of the process and accordingly the system technology for impregnation depends on the concrete operating conditions of the winding material. The criteria here are mainly the mechanical and electrical stress of the winding goods in their operation.

Process Engineering for Impregnation in Non-Electrical Applications

In non-electrical applications, impregnation is used to seal the micro-porosities of, for example, metal castings such as crankcases of combustion engines or mineral workpieces in order to make them refractory, for example.

For the metal impregnation, the “MTR” type equipment is used. The plants of this type consist of a container system with a central crane system. The individual process steps take place in the various containers, the passage of the workpieces through the system is fully automatic.
