RYOWO was founded in Hong Kong in 1978. We develop, produce and market open type water cooling towers for industrial and commercial usage. We have been a member of Cooling Tower Institute, USA (CTI) since 1982. Our main office is located in Hong Kong, where we have engineers, experienced workers and advanced computing systems to promote our products and to meet our customers' needs. Our main production plant is located in Shenzhen, China. We aim to develop and manufacture most of the product components in our factory, and up to now more than 90% of Ryowo cooling towers' components are manufactured in-house. This not only helps us in the control of costing and quality, but also helps us in providing economical and reliable products to our customers. Besides, we have a full range of spare parts for our towers and for other similar towers.
