To provide spot cooling for workers within a large enclosed factory.
 
Efficient cooling had to be provided for factory workers without having to cool the entire area - which would be both expensive and a waste of valuable natural resources. Large Breezair industrial air coolers were fitted on the roof of the factory using vertical ducts to direct cool air only to areas where it was needed by workers
This solution not only improved the health and safety of the workers, but led to increased productivity as working conditions became more comfortable.

Summer Design Condition:
32°C dry-bulb temp
40% relative humidity

Total area: 110m x 40m=4,400m2

Height of plenum above floor: 4.5m

Total cooled volume:
4,400 x 4.5 = 19,800m3

Breezair model : 27 x EA150D

Each cooler discharges into one vertical duct 4.2m long and 870mm x 870mm square. Special plenum design: 4 corner posts 600mm long, supporting pyramid base plate and no grille. Each Breezair cooler serves one spot in the factory.
