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.

FAQ
Biogas & Digesters — questions answered
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.
