Air Coolers for Hydroelectric Power Plant Generators

Air Coolers for Hydroelectric Power Plant Generators

In hydroelectric power plants, generators convert mechanical energy from water turbines into electrical energy. These generators produce significant amounts of heat during operation. Effective cooling is critical to maintain generator efficiency, prevent overheating, and extend the lifespan of the equipment. The existing cooling system was not sufficient to handle the thermal load, prompting the need for a more efficient air cooling solution.
