Generally, misting systems work best where lower humidity is present with efficiency decreasing as humidity increases. To overcome high humidity or to cater for situations where specific targeted areas need to be cooled, fitting misting rings to the front of electric fans is the solution. The advantage here is the added convective cooling ( wind chill factor ) that is created. Misting rings can be retro fitted to existing fans by attaching them to the front of the fan guard by simple use of cable ties or similar fixing methods.
