Engineering hub

Measurements with
the context to use them.

Purpose-built tools for air and water systems, with visible units, assumptions and source references.

Valve flow calculator

Choose an exact supported valve version and setting, or enter a verified coefficient from your own reference. Manufacturer data and measurement-port definitions matter.

Calculate valve flow

HVAC calculators

Duct area and conditional capacity, run pressure losses, fan pressures and speed changes, pump head, heat duty, air changes and unit conversions.

Commissioning handbook

A field reference for pressure terms, measurement methods, balancing, controls verification and commissioning records, with NZ guidance links.

Open the handbook

Use the correct system model, instrument locations and project acceptance criteria. Velocity-based duct capacity is conditional; fan duty comes from the exact manufacturer's curve. Published coefficients are not a claim of equivalence to every HyTools calculation or valve generation.
