A misting system only works as well as its weakest component. Use this checklist before you compare quotations.

1. Purpose decides the design

Cooling, humidification, odour control and dust suppression need different nozzle densities, run times and controls.

2. Pressure

Low-pressure systems are simple but produce larger droplets that can wet surfaces. High-pressure systems produce finer fog that evaporates quickly.

Look for stainless steel orifices, anti-drip check valves and cleanable designs. See our mist nozzles.

The pump must deliver the total nozzle flow at the design pressure with margin. See misting pump set-ups.

Fine orifices need filtration; hard water needs softening or RO to avoid scaling.

High-pressure rated tubing and fittings such as slip lock connectors avoid leaks.

Timers, humidity or temperature controllers and zoning keep water use in check.

Ask what routine checks are needed and which spares to keep.
