We are permanently working on innovations and following up new ideas. This approach results in better and optimized products and production processes and this often leads to even less expensive products combining new possibilities and features. This is why even quality products need to be replaced from time to time. In the following please find an overview of production ends, final purchase orders and spare parts guarantees.
