Model HS Floating Aqua-Lator is a self-contained lightweight aerator f o r converting existing holding ponds into process water cooling facilities. The submersible, propeller-driven pump draws water from a trough and sprays it into the air by high velocity pumping action. The spray falls into a catchbasin surrounding the narrow trough, and may be rechanneled into another trough for further cooling action. All machined parts and castings of the unit are made f r o m stainless steel or naval bronze and, according to the company, are virtually indestructible in normal use. In addition to cooling water and providing an attractive fountain for holding ponds, the unit is designed to 91 strip gases such as CO, and H 2 S . Welles Products Corp.
