Hollow Plastic Ball Covers for Power-Plant Cooling Ponds

The challenge

  • Evaporative makeup-water demand
  • Algae in warm open basins
  • Wide temperature swings
  • Need for periodic equipment access

How Armor Ball® helps

Armor Ball® reduces evaporative makeup-water demand on cooling ponds by covering 91% of the surface, and blocks the UV that feeds algae in warm open basins — a chemical-free way to protect water quality and cut makeup costs.

The HDPE holds up across a −70°F to +160°F operating range and through wide temperature swings. When intakes or equipment need access, the free-floating balls push aside and then re-cover the surface automatically.

What to look for when covering a power-plant cooling ponds surface

  • Makeup-water savings: Evaporative savings depend on climate and surface area — estimate them with the evaporation calculator before sizing.
  • Equipment access: Plan for intake and equipment zones; the balls move aside and re-cover, so no cut-outs are required.
  • Temperature swings: The −70°F to +160°F rating handles seasonal extremes; confirm your operating range.

Outcomes

Lower evaporative makeup-water demand
Chemical-free algae control
Wide operating-temperature tolerance
Equipment access without removing the cover

FAQ

Power-Plant Cooling Ponds — questions answered

Can equipment still access a pond covered with balls?

Yes. The balls are free-floating, so equipment and intakes can push them aside as needed; the cover then re-arranges itself back to a 91% layer automatically.

Will a ball cover affect cooling performance?

The cover reduces evaporative heat loss and makeup-water demand while letting equipment and intakes push the balls aside as needed. Share your pond's duty and access points so AWTT can confirm the right configuration.
