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 traps a buffer of air at the surface to insulate the liquid at R-2, retaining the heat that biological processes depend on and supporting up to 70% heating-cost reduction in temperature-sensitive applications.
The same cover suppresses odor and surface emissions, is maintenance-free, and self-adjusts to changing levels. For higher insulation requirements, AWTT's range extends to R-17+ with covers such as Hexprotect® MAX R.
What to look for when covering a biogas & digesters surface
- Insulation target: A single ball layer is R-2; if your process needs more, AWTT's covers reach R-17+ — share your target so the right product is specified.
- R-value documentation: Request R-value and material documentation where applicable for your engineering review.
- Process temperature: The −70°F to +160°F range suits many heated surfaces; confirm your operating temperature.

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.
Can a ball cover provide more than R-2 insulation?
A single Armor Ball® layer provides R-2. For higher insulation, AWTT's product range extends to R-17+ with covers such as Hexprotect® MAX R — tell us your heat-retention target and we'll recommend the right cover.
