Find answers to common questions about cooling towers and our products.
Evaporative cooling is using water evaporation to remove heat from a system at a low energy consumption and virtually maintenance-free.
A cooling tower is a heat exchanger which air and water brought in direct contact to reduce the water’s temperature. Small volume of the water is evaporated, reducing the circulating water temperature through the tower. The water is distributed through nozzles onto blocks of material called, “fill”, which exposes as much water surface area as possible for maximum air-water contact. As the water flows through the cooling tower, the exposed air is pulled through the tower by the electric motor-powered fan. As the water evaporate, creating the cooling, the cooled water is pumped back to the industrial process where it absorbs heat again.
We offer a range of direct and indirect cooling towers in crossflow and counterflow configuration. We offer both factory assembled and field-erected solutions to meet the specific requirements of our client. Design for optimal performance, durability and ease of maintenance, a Ryowo tower is engineered to work together as an integrated system for the best performance and longevity.
