Enabled cooling in large open spaces without wetting people, floors, or equipment.
Demonstrated the system’s effectiveness through an on-site trial, allowing the customer to directly experience the temperature reduction.

A car manufacturing plant striving to improve working conditions identified heat countermeasures during summer as a top priority.
In particular, the receiving area for parts delivered by suppliers, which also serves as a truck yard, was a critical concern. Although the area has a roof, it is exposed to outdoor air and becomes extremely hot, making heatstroke prevention an urgent issue at this site.

Urgent Need for Heatstroke Prevention in the Receiving Area

Because this area is an open space, installing air conditioning systems was not expected to be effective. As a countermeasure, large industrial fans were installed on the ceiling; however, they blew air that had been warmed near the ceiling by radiant heat from the roof, resulting in negligible cooling effect.

They approached us for a solution to find a way to enhance cooling effects, even slightly, while utilizing these existing fans.

We proposed a mist cooling system that involves mounting specialized nozzles on existing fans to spray extremely fine mist, Semi-Dry Fog. The fog is carried by the fan’s airflow, dispersing throughout the space and cooling the large open areas through the heat of vaporization.

We conducted an on-site demonstration with operators and supervisors, allowing them to experience firsthand the temperature reduction and clearly observe the system’s effectiveness.

The heat of vaporization from the fine fog reduced the ambient temperature in the receiving area by 3–5°C.
The high ceiling provided sufficient distance for the fog to evaporate, ensuring cooling in the open space without wetting people, floors, or equipment.
The system received extremely positive feedback and was subsequently implemented in other work areas beyond the receiving area. It has also been expanded to other factories, significantly contributing to improved working conditions.
