The Industry's First Air Handling Unit (AHU) Selection Software 3D

AirSelect3D is the fastest, most efficient way to select an accurate air handling unit (AHU) — in the browser, in 3D. A manufacturer configures a complete unit — filters, fans, heating and cooling coils, heat recovery, casing and acoustics — in about five minutes, running each component through its supplier's own certified calculation engine, and ships every export the industry needs in one click: the AutoCAD DXF drawing, the Eurovent-compliant printout (ECP-05-2026, with the ErP verdict), and the pricing sheet. It runs in the browser with no install, and it is the industry's first drag-and-drop 3D air handling unit selection software: you design the unit in 3D, you don't just view a rendered result.

Built around your own suppliers

AirSelect3D is delivered as a version built around your production. We integrate your own component suppliers' calculation DLLs or certified catalogs — not a fixed list — so the unit is priced and sized on the exact fans, coils, filters and heat-recovery brands your factory already buys. Six supplier engines are wired live today (Camfil for filters, Ziehl-Abegg and eBM Papst for fans, Friterm for coils, Recuperator and Klingenburg for plate heat recovery, Hoval for rotary heat recovery) and your own list is added on request. Any requirement your factory works with can be built in: your pricing logic, production drawing export for the shop floor, custom report layouts and your own unit range.

Compliance computed live

Every edit recomputes compliance in real time: specific fan power (SFP) to EN 16798, the winter and summer fs-Pref ratios and Eurovent energy class per ECP-05-2026, the ErP (NRVU) verdict, and octave-band sound power. A non-compliant configuration is visible immediately — before the quote ships, not after a consultant rejects it. Each selection is stamped with the engine version, catalog version, selection ID and timestamp, so any project can be replayed and audited months later.

What you ship

One click renders a 14-page technical data sheet: general-arrangement drawings in 2D and 3D isometric, a bill of materials in CSV or XLSX, octave-band sound power, fan and coil performance curves, and DXF (AutoCAD) plus IFC (BIM) exports for your coordination team.

Key facts and numbers

Frequently asked questions

What is AHU selection software?

AHU selection software sizes and configures air handling units: it selects fans, coils, filters and heat-recovery components against an operating point (airflow, external pressure, design temperatures), computes pressure drop, SFP and energy class, and produces the technical documentation needed to quote the unit. AirSelect3D does this in the browser with a 3D drag-and-drop designer and certified supplier calculation engines.

Can you build a custom version for our factory?

Yes. We integrate your own component suppliers' DLLs or catalogs (not a fixed list) and add the requirements your factory works with — pricing logic, production drawing and BOM export, custom report layouts and your own unit range.

Which manufacturers' data does AirSelect3D use?

Each supplier's own calculation engine or certified catalog runs in an isolated side-car: Camfil filters, Ziehl-Abegg and eBM Papst fans, Friterm coils, Recuperator and Klingenburg plate heat exchangers, Hoval rotary heat recovery. Every result is tagged with its source — live DLL or catalog.

How does AirSelect3D compute the Eurovent energy class?

It computes winter and summer fs-Pref ratios per Eurovent ECP-05-2026, checks SFP to EN 16798 and the ErP (NRVU) requirements, and stamps the verdict — with engine version, catalog version and selection ID — into the printable dossier for full auditability.

Can I export drawings and BIM files from AirSelect3D?

Yes. One click produces a 14-page technical data sheet PDF with 2D and 3D general-arrangement drawings, DXF for AutoCAD, IFC for BIM, and a bill of materials in CSV or XLSX.
