FREQUENTLY ASKED QUESTIONS

Find answers to common questions about cooling towers and our products.

What is evaporative cooling?


Evaporative cooling is using water evaporation to remove heat from a system at a
low energy consumption and virtually maintenance-free.

What is a cooling tower?


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.

What types of cooling tower do Ryowo make?


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.
