Cooling Tower Fans
Mechanically forced-draft or induced-draft cooling towers are used to remove the heat absorbed in the circulating cooling water systems. The Fan is a very important component of the towers. All of our fans including cooling tower fans installed worldwide are saving energy at the rate of 250MW. Parag fans provide a less expensive and quick fix to reducing the auxiliary power consumption in a plant.
