How to Use the Case Library
The case library documents real ZeAllgrate installations by industry — each with the environment, the engineering specification and the outcome. Use it three ways: to see the selection process applied to your industry, to build a reference list for a client proposal, and to check the resin and hardware choices against your own service conditions before sending the RFQ. For a similar project, bring the chemical list and span drawing to the quote — the engineering team maps the specification to the actual service, as the case studies document.
