GLOSSARY
Misting Nozzle
A misting nozzle is the precision orifice that atomises pressurised water into fine droplets. Professional mist cooling nozzles have 0.15–0.3 mm orifices made from brass or ceramic, with anti-drip seats that prevent water release when pressure drops.
Also known as: Mist nozzle · Atomising nozzle
Nozzle specifications
- Orifice size: 0.15–0.3 mm — larger orifices produce wetter output, smaller orifices restrict flow. 0.2 mm is typical for outdoor cooling.
- Material: Brass for cost-effective standard applications; ceramic for chemical-sensitive environments (greenhouses, pharma).
- Anti-drip seat: Spring-loaded internal mechanism that seals the nozzle when line pressure drops below 25 bar, preventing post-shutoff drips.
- Fitting thread: Standard 10/24 UNC or M6 metric, brass-to-stainless compatible.
Spacing and coverage
A single nozzle in Indonesian outdoor conditions (29–34°C, 70–85% humidity) covers roughly 1.5–2 m² effective cooling zone. Nozzle spacing is 60–80 cm for hospitality applications, 30–50 cm for intensive propagation or humidification, 100+ cm for perimeter-only applications.
Maintenance
Nozzles require cleaning every 6–12 months in standard water quality; every 3–6 months in hard-water or salt-air environments. Cleaning takes 30 seconds per nozzle — submerge in citric acid solution, rinse. MistSystem Premium Maintenance Contract includes scheduled nozzle cleaning.
