Product

Epoch 24-ft 5-Blades 62 RPM HVLS Fan with Epoch 3.0 Motor and Controller - 170Nm / 1.5kW / 2.0 hp

Problem

Involute Technologies manufactures and distributes engine components including gears and shafts for automotive, marine, and industrial sectors.
The shop faced problems with poor air movement and ventilation, affecting employee comfort and work efficiency.
During summer, the shop ceiling absorbs heat which increases the temperature at ground level.
The increased temperature inside the shop reduces employee productivity and working comfort.

Solution

Installed 4 × Epoch 3.0 24-ft HVLS Fans with the following specifications:

Motor : Epoch 3.0
Coverage Area : 30,000 Sq. Ft. (2,787 Sq. m)
Speed : 62 RPM
