HVAC COMMISSIONING & BALANCING

Commissioning tools for the person on the ladder

Field Kit puts every traverse calculation, pre-check and tolerance table in one offline app — designed with balancing engineers who work in gloves, in plant rooms, with no signal.

Resume: AHU-02 traverse

The field-first tool for commissioning

Field Kit is where the whole job comes together — the technician taking readings, the engineer witnessing them, and the office producing the certificate all work from the same numbers.

Calculate on the spot

Traverse points, duct area, fan laws, K-factors and air changes — worked out in steppers and chips, not a keyboard, on any device.

Catch drift early

Every reading is checked against the design value and tolerance you set, so a −21% branch gets flagged while you are still standing under it.

Leave with the record

Sheets, photos and sign-offs export as CSV or PDF the moment you get signal — the witnessing pack writes itself.

Purpose-built for your trade

One app, four jobs. Field Kit adapts to whoever is holding the phone without asking them to learn a new system.

Get the reading right the first time

01
Hole patterns, solved

Enter duct size and Field Kit returns the point grid and distances from edge, with a warning when there isn’t enough straight length upstream.

02
Pitfalls before you climb

Each method carries the mistakes that ruin the result — bend distances, damper positions, instrument ranges — shown once, then out of the way.

03
One-handed entry

Steppers and common-size chips cover about nine in ten entries, so the keyboard only appears for plant names and notes.

Watch out
Needs 4 000 mm straight upstream (10× equiv. dia). Bend at 1 200 mm → readings unreliable.

Real work, not paperwork

01
Works with no signal

Everything is on the device: calculators, tables and your sheets. Plant rooms and basements behave exactly like the office.

02
Evidence attached, not chased

A photo of the plate, a voice note and a location pin ride along with the reading, so nobody asks which duct this was.

03
Exports the office accepts

CSV that drops into your existing workbook, and a dated PDF sheet per system for the witnessing file.

Software built for the plant room

Create your company account, buy a seat for each technician, and invite the crew. Everything they record from then on carries their name.
