Large-space Cooling and Humidification System COOLJetter® Dome

Product outline

Dispersing fine fog (Semi-Dry Fog® [*1]) using a fan, this energy-saving cooling and humidification system (mist fan system) lowers ambient temperatures by 2–4°C via evaporative cooling and boosts humidity levels.
Suitable for large indoor spaces, buildings with constantly open entrances and other such locations where conventional cooling and humidification systems are ineffective, this product provides outstanding results in terms of lowering room temperatures, preventing heatstroke, keeping dust down and more.


• COOLJetter® Dome incorporates hydraulic spray nozzles to provide effective cooling and humidification for large spaces.
• It disperses Semi-Dry Fog® (*1) over a wide area using a fan to create a cool zone.
• It reduces temperatures by 2–4℃ with evaporative cooling of fog.
• Because it cools entire zones rather than narrowly defined areas, this system is suitable for preventing heatstroke among constantly-moving workers, athletes and other such users.
• It can be also used for dust suppression, static charge prevention, and humidification.
• Support customers in site investigation, layout design, installation work and after-sales services.

*1) We define Semi-Dry Fog® as a fog with a mean droplet diameter (mean fog droplet size) of 10–30 μm.
Because this fine fog does not include large droplets which can result in wetting, it provides superb performance quality for human users.
"Dry mist," despite its similar name, has no specified droplet diameter as part of its definition. Dry mist droplet sizes vary significantly by producer and product.
