Polyester enclosures are used for different technical purposes depending on the area of application. BERNSTEIN offers several designs for this purpose – tailored to standard industrial applications as well as to special requirements in railway or explosion protection technology.
Standard polyester enclosures
For mechanical and plant engineering
The standard polyester enclosures are suitable for universal use in mechanical and plant engineering. They impress with their robust design, simple assembly and versatile use in industrial applications.
Railway polyester enclosures
For railway vehicles and railway infrastructure
These enclosures are specially designed for use in railway technology and fulfil increased requirements for fire protection and material behaviour. They are used in railway vehicles and in stationary railway applications.
