Engineering reference case profiles spanning the industries LONGWELL supplies — from AI data center CRAH FanGrid retrofit to battery gigafactory ATEX dust collection. Each profile documents the engineering challenge, solution architecture (LONGWELL SKU BOM), measured outcomes, and engineering lessons.
Send your duty point and LONGWELL Engineering returns a sized BOM with AMCA test data within 24 hours.
Everything on this page came out of our own project correspondence — photographs customers took themselves and sent back to us. None of it is staged, and none of it was shot by us. We publish it because a photograph of a crate in someone else’s van says something a studio shot cannot.
We grade what we have honestly. L5 — a machine running on site — is the one level we cannot yet show, so the scale above stops at L4.

Where a photograph could only be cleaned by destroying it, we left it out. Countries are given only where they add engineering context.
