How an enquiry works
-
Send your application data
The eight parameters of your installation are enough for a first check: country, atmosphere, zone, group, temperature, ambient conditions, motion duty, drive and feedback.
-
We check the fit
We compare your data with the DX marking and ratings and reply with what fits, what does not and what is still open. This is a technical assessment, not a quotation.
-
Evaluate for a defined project
Samples, documents and delivery are discussed for a defined project.
