Hollow Plastic Ball Covers for Biogas & Digester Surfaces

The challenge

  • Heat loss from temperature-sensitive processes
  • Odor and surface emissions
  • Need for R-value documentation
  • Maintenance burden of mechanical covers

How Armor Ball® helps

On digester-adjacent and process surfaces, an Armor Ball® layer adds R-2 insulation to retain heat — supporting up to 70% heating-cost reduction in temperature-sensitive applications — while suppressing odor. The cover is maintenance-free and self-adjusting.

How much insulation does a ball cover add?

A single Armor Ball® layer provides R-2 insulation per AWTT published data, helping retain process heat. For higher insulation requirements, AWTT's product range extends to R-17+ with covers such as Hexprotect® MAX R.
