Floating Thermal Insulation with Ball Covers
How it works
An Armor Ball® layer traps a buffer of air at the liquid surface, insulating it at R-2. That slows the heat loss that bleeds energy from heated process water, reducing heating costs up to 70% in temperature-sensitive processes such as digesters and heated tanks.
The cover 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 — so the same simple, floating approach scales to demanding heat-retention duties.
What to look for
- Insulation target: A single ball layer is R-2; share your heat-retention target so AWTT can confirm whether a higher-R cover (to R-17+) is the better fit.
- Process temperature: The −70°F to +160°F range suits many heated surfaces; confirm your operating temperature.
- Savings estimate: Heating-cost savings depend on temperature, climate, and surface area — model yours with the heat-loss ROI calculator.
FAQ
Floating Insulation — questions answered
How much can a ball cover cut heating costs?
By adding R-2 insulation to the surface, Armor Ball® can reduce heating costs up to 70% per AWTT published data in temperature-sensitive processes; results depend on process temperature, climate, and site conditions.
What R-value does a single ball layer provide?
A single Armor Ball® layer provides R-2 per AWTT published data. For higher insulation, AWTT's range extends to R-17+ with covers such as Hexprotect® MAX R.
Does the insulation work in cold climates?
Yes. The HDPE is rated from −70°F to +160°F and is not damaged by ice or snow, so the R-2 surface layer keeps retaining process heat through cold-weather operation.
