How the guides should be used
The knowledge articles provide original explanatory guidance and practical questions for selection. They are not a substitute for an approved sizing calculation, current product instructions or project engineering. Numerical examples are identified as examples; historical capacity values are not universal current product guarantees. External manufacturer links provide reference context and do not imply affiliation.
Languages and document control
English is the technical reference language. The website includes independently written sales pages and inquiry forms in 21 languages including English. The detailed knowledge library and supplied public catalogues are in English. Technical grades, series codes and units are kept unchanged in translated pages. Contractual specifications and local-language technical translations should receive a project-specific review before issue.
Corrections and updates
