Everything you need for ventilation calculations

From a visual network editor to ready-made reports — with a full transfer of your legacy desktop projects.

01 · Editor

Network editor

A visual canvas editor for nodes and lines. Build a network of any complexity right in the browser, trace it over a floor plan or site layout, and keep large projects under control.

Floor-plan tracing: image upload with free scaling and positioning against a grid
Named filters for navigating large networks (by pressure drop, flow rate, objects)
Full Undo / Redo
Reference nodes (atmosphere), fans, dampers and doors as objects on lines

02 · Calculation

Automatic hydraulic calculation

One click balances flow rates and pressures across the whole network using the independent-loop method. Fans, dampers and doors are accounted for as local resistances.
