CrossHatch Cleanroom Modeler

Built to your grid, not a generic one.

The airflow numbers come off the drawing itself.

• Every room listed by name, with floor area, volume, total CFM and the resulting ACH

The ceiling is where cleanroom quotes leak margin. The modeler works in the real geometry of your system: your module, your tee profile, and the clear opening a tile actually drops into once the grid takes its share.

Tiles that run past a wall are cut at the wall, and the area that survives is the area you are quoted on — not the nominal tile.

Engineering Mode turns a cleanroom drawing into a design that has been checked. It runs as a sequence — classification, ceiling set-out, supply air and coverage, return path, pressure cascade, air balance, plant — where each stage is measured against the one before it, and a stage stays locked until the work it depends on is actually done. Targets come from the standard you're building to: ISO 14644, USP <797> and <800>, EU GMP. Every open item tells you the move, not just the fault — how much air to add, how many units to place, how much more free area to find. Figures nobody has stated are reported as unknown rather than assumed, and any number the tool worked out for you says so on the page it prints. When the last stage clears, the plan, the airflow schedule and the sign-off sheet all come out of the model you were just working in.

Drop a ceiling grid into any room, fill it with the units you'd actually install, and the performance figures build themselves — derived from the equipment you placed and the room you drew, not from a rule of thumb.

• A whole-structure total beneath the rooms

• The drawing itself is embedded at the top, so the layout and the numbers arrive as one document
