A Dogmatik AHU.SELECTOR Alternative: How AirSelect3D Compares

Dogmatik's AHU.SELECTOR is a capable, genuinely modern piece of software — if you're evaluating it, you're already looking in the right category (independent, web-based AHU selection for manufacturers), not at the general HVAC-design tools that clutter most "best of" lists. This is an honest look at where AirSelect3D lines up next to it and where the two differ, written by the AirSelect3D team, so weigh the source and verify Dogmatik's current specifics on their own page.

Where they're genuinely similar

Both are web-based, no-install platforms built for AHU and component manufacturers. Both offer 2D/3D visualization (Dogmatik uses a WebGL graphic engine; AirSelect3D uses a React-Three-Fiber canvas). Both integrate manufacturer component data across filters, coils, fans, plate and rotary heat exchangers, attenuators and dampers. Both export the documents a real quote needs: technical data sheets, DXF, IFC, BOM and tender/price output, plus fan curves and psychrometric (h-x) diagrams. If your shortlist is "modern browser-based AHU selectors," these two belong on it together.

Where they differ

The 3D model: authoring vs. visualization. Dogmatik's own materials describe 2D/3D visualization of the configured unit. AirSelect3D's 3D canvas is the design surface itself — you drag modules onto the casing, they snap to the airflow centreline, and dimensions plus results recompute as you move them. Both give you a 3D picture at the end; the question for your team is whether they want to design in 3D or view the result in 3D. Demo both to see the difference for yourself.

Compliance computation. Dogmatik publishes ErP calculation and energy data. AirSelect3D computes the full Eurovent ECP-05-2026 energy class — separate winter and summer fs-Pref ratios — and the ErP (NRVU) verdict live on every component change, with the derivation stamped into the dossier. If your buyers ask for a certified-class number both seasons and a full audit trail, compare how each tool surfaces that, and how early in the workflow.

Data-source transparency. Both integrate supplier data. AirSelect3D additionally tags every result row with its source — DLL (the manufacturer's own engine) vs. catalogue — so an auditor can see exactly where each number came from. If provenance matters for your certification submissions, ask each vendor how they expose it.

How to choose between them

Honestly, these are close enough that the decision should come from a live, side-by-side demo on your real unit, not a feature list. Time a complete selection on each — template to exported dossier — and watch specifically: does the 3D view let you design or only look; does the Eurovent/ErP verdict update as you edit or only at print; and can you trace every performance number to its source. Then pick on what your sales engineers actually felt.
