Quick calculators, honest formulas
Free, no account, assumptions stated. Each one answers a single question with the same physics engine behind the full product — and tells you when the single-point answer isn't enough.
Leak cost calculator
LiveHole size + line pressure + tariff → leak flow and €/yr, from the choked-orifice physics. The formula every leak survey quote should be checked against.
Pipe pressure drop
Coming soonDiameter, length, flow → Δp by Darcy–Weisbach. Find out what that long thin drop line is really costing.
Receiver sizing
Coming soonDemand swing + allowed band → tank volume and resulting start frequency, from the pump-up physics.
Specific power benchmark
Coming soonkW and delivered flow → kW/(m³/min) against the reference band for your pressure class. The 10-minute room health check.
CFM / FAD unit converter
Coming sooncfm ↔ m³/min ↔ l/s ↔ Nm³/h without the reference-condition traps.
A calculator answers one point. Your plant is a system.
When the single-number answer isn't enough — because the answer depends on your pipes, your storage and your demand peaks — model the whole system.
