Questions manufacturers ask first
Do you build selection software for products other than fans?
Yes. We have built silencer selection software for Frapol, diffuser selection software for SMAY, a hypoid gearbox and drive selection program for HF Inverter and a differential pressure system and project designer for Fläkt Group. See custom HVAC selection software.
Where can I see programs you have already built?
In the case studies: selection programs built for manufacturers such as BVN, CFB, UVENTS, Frapol and SMAY, each described with its scope.
Can I try the engineering calculations first?
Yes. The free engineering calculators — FEI, ErP 2026, fan acoustics (VDI 3731), duct sizing and more — run in the browser with no sign-up.
