Batches traceable to a per-cabinet test record
Product documentation for these three lines is issued by the original manufacturer.
Envicool, Bainard and Yizhou build their own products. Those products are not made by ems-rack.
We size the unit for the load, mount it in our enclosure or containment scope, and act as the single contact for the whole delivery.
Datasheets and product documentation for these three lines are issued by the original manufacturer, not rewritten by us.

We return the list marked by origin — own production or distributed brand — before you commit to anything. Requests are accepted or explicitly refused, never silently dropped.
What comes back
Documents leave as PDFs, the drawing set goes out for approval, and the quote names the Incoterm and holds for 30 days.
Every request is either accepted or explicitly declined. It is never silently dropped. No reply means it never reached us — send it again and it is treated as a first contact.
