Mechanically forced-draft or induced-draft cooling towers are used to remove the heat absorbed in circulating cooling water systems. The Fan is the most essential component of the cooling tower. Impact fans regularly provide efficiencies of 15-40% over other makes in wet cooling applications like cooling towers. All of our cooling tower fans installed worldwide are saving energy at the rate of 250MW. Impact fans provide a less expensive and quick fix to reducing the auxiliary power consumption in a plant.
