An apparatus has a housing with at least one gutter, a body of fill material disposed in the housing, a liquid distribution system disposed in the housing and positioned above the fill material, a fan positioned below the body of fill material for blowing air upward through the fill material, a liquid collection assembly positioned between the fill material and the fan for collecting the liquid gravitating through the fill material. The liquid collection assembly has at least one troughless, open sided surface element angled so gravity is utilized to capture the down flowing liquid to provide a barrier between the fill media and the fan and to carry the liquid down the surface element and into the at least one gutter.
