The Howden cooling fan selection software stems from 1983 and at that time released as "EFanSel". Constant development resulted in the release of Howden Select in 2015. The integration of helpful features into the selection software resulted in a user-friendly tool. Howden Select assists experienced users in finding solutions very quickly as well as enabling less experienced users to come to a proper cooling fan selection. The program includes the latest and most recent information about our fan series and updated with the latest information on fan masses, moments of inertia and blade natural frequencies, due to constant improvement of our hand lay-up cooling fans production method.
