CRISP — Compressor Replacement for Immediate System Performance

When a big machine like a compressor is up for replacement, the cheapest purchase price is rarely the cheapest over its lifetime. CRISP is a method that pushes tenders toward the option with the best total cost of ownership (TCO) — purchase plus energy plus maintenance over the machine's whole life — so we buy the genuinely most efficient machine, not just the one with the lowest sticker.

In-house R&D method, applied first at RWZI Nieuwveer (see Nieuwveer TCO model). It informs procurement decisions; the realised savings land in operations, so no separate €/yr is booked here.
