DA17 Cooling Towers

AIRAH’s technical application manual, DA17 Cooling Towers, has been updated for the first time since 1997. The recently released DA17 is the third edition of this indispensable resource and builds on previous editions by including comprehensive information on new cooling tower technologies, management strategies and applications.

In many buildings cooling towers can account for up to 50 per cent of water use, new technologies outlined in this manual minimise tower water consumption.

Anyone owning, operating, designing, building, installing, commissioning, maintaining or assessing a cooling tower should they have a copy of this manual on their bookshelf.
