Cooling Tower Balls

Cooling Tower Balls (CTB) are a floating ball cover that controls algae by simply blocking direct sunlight. Eliminating sunlight by covering the complete water surface creates an effective shade factor to control the growth of algae. The pictures below show a case study comparison of 2 cooling tower systems from the same customer. One cooling tower system utilized CTB while the other system received no algae treatment. RSI has installed millions of CTB in cooling towers since 2009.

Sizing

Approximately 10 balls are needed per square foot of water surface.
Examples:
5' x 10' sump = 50 square feet x 10 balls per square foot = 500 balls
10' x 10' sump = 100 square feet x 10 balls per square foot = 1000 balls
Note: Sizing so there are a few extra balls is fine.  The extra balls will simply start a second layer with added benefits.
