History of Aquafan

1950's

Early developments

A modified water turbine as used in hydro electric plants, was set up to drive a fan to test the idea of using the kinetic energy in the water to convert into a rotating movement to drive a fan. The fan was engineered to provide sufficient air flow as used in wet cooling towers. Credits of the invention go to Sir Edward B. Talbot, who is until today on board with the group as a consultant for further developments.

The designs were filed for patenting in 1962.

1970's - 1980's

Initial commercialization

First units went in operation back in the 1960-ties in the USA as AQUAFAN. Since the late 1970-ties it became popular in Germany. Firstly as Kidde, after take-over of Kidde GmbH by Wacon as AQUAVEN. Thousands of units were sold and a lot of them are still operational in Europe and USA, some of them even 30+ years later.

Late last century

Growth in EU & US

The later decades were a period of steady growth. In the USA the concept was used for water aeration in lead removal procedure in the state of California. In the European markets, the concept became popular for application in industrial areas.

Come-back in Asia

For launch in Asia market and on the initiative of WATCO Group PTE from Singapore the concept was re-engineered to be applied in larger cells. In 2016 the group proceeded engineering the hybrid version to meet the market’s expectation to be able to apply the concept of low energy demand cooling in architectural friendly designs in  comfort cooling applications. 

As from 2014 the first new AQUAFAN cooling towers were built in Middle East and South East Asia.
