The vendor's free audit is a sales call. This is your model of your plant.

You have to justify the capex to management — and quietly, you have to not buy the wrong machine. An independent model of your own system shows what a VSD, a setpoint change, a receiver or a leak program is worth in €/yr, with the risk shown next to the saving. Before the purchase order, not after.

The questions it answers

Decisions you're probably sitting on right now

Model your room in an afternoon: nameplate specs, pipe lengths off the drawings, your tariff. Then ask it anything — every run takes about a second.

"Is a VSD actually worth it here?"

Depends entirely on your load profile — which the model has. On the demo plant's 50% duty: −€6,487/yr, a 2–3 year payback. On a plant running near full load: much less. Now you know before the vendor's quote arrives.

"Can I lower the pressure without breaking production?"

The saving is free money — €2,472/yr on the demo plant — but the model also shows minimum point-of-use pressure dropping 5.91 → 5.40 bar. If your most sensitive machine needs 5.5, you just found out at your desk instead of on the night shift.

"What is our leak problem actually costing?"

One 3 mm leak ≈ €2,037/yr. Model your known leaks — or run the 2 a.m. baseline — and the leak survey suddenly has a business case with a payback period on it.

"Why is pressure low at the far end of the shop?"

Because physics. The model sees your pipe losses and demand peaks, so it shows starvation where and when it happens — and what pipe upsizing or local storage would actually fix.

The management meeting

Walk in with a comparison table, not a vendor brochure

The export is built for exactly that meeting: baseline vs. options, Δ€/yr per option, the operational side-effects (starts, pressure margins), and every assumption printed. When finance asks "says who?" — the numbers come from a calibrated model of your own plant, and the tool has no machine to sell. See how the modelling works.

And when the answer is "don't buy it" — like the bigger receiver's honest ±€0 — you just avoided a five-figure mistake for the price of an afternoon.

The decision on the table is fifty grand. Model it first.

Bring the decision you're actually sitting on — a compressor replacement, a VSD question, a pressure problem. Access is open by application right now: we'll help you build the model of your plant and get to a number you can take to management.
