Armor BALL™ COVER SYSTEM
AWTT INC. Armor Balls™ cover systems offer highly
effective solutions to problematic liquid storage systems such
as municipal and industrial wastewater, treatment processing
plants, metal and petrochemical plants, leachate, airports,
raw water reservoirs and other applications for heat retention
and waterfowl deterrent.
High surface area coverage is achieved by placing a sufficient
amount of balls on the surface of the liquid. The balls arrange
themselves to provide coverage of up to 91%. The result is a
thermal insulation barrier which combines the insulation factor
of the air held in each ball with the poor heat conductivity
of plastic. While the air pockets between the balls are not
sealed, they also contribute to this insulation system, which
dramatically reduces heat loss and light transfer. The cover
also reduces liquid loss through evaporation and prevents odor
problems.
The Armor Balls™ barrier, contrary to standard covers, does
not represent an obstacle to static, moving or dipping equipment.
The balls can be easily pushed aside and the cover reforms itself
as the basin and obstacles change configuration, as in a clarifier.
In fact, the balls will keep up with liquid level, rising, lowering
and restacking themselves as needed.
Armor Balls™ is also an effective wildlife deterrent. When entirely
covered, the body of water becomes unattractive to waterfowl
and other wildlife such as deer. They simply don't recognize
it as water.
Compared to netting, Armor Balls™ are not sensitive to ice or
snow damage and do not require any kind of support.
The Armor Balls™ Advantages
- Quick and simple to install
- Deters waterfowl from landing on covered waters.
- Each ball is made of long lasting, UV resistant, virgin
HDPE
- Heating cost reduced by up to 75%
- Decrease liquid loss through evaporation by up to 90%
- Allow movement of equipment through liquid
- Adjusts to variation of the liquid level by spreading &
stacking
- Fast and Effective solution to odor problems "
- Virtually maintenance free
- Cannot tear like conventional membrane cover "
- Reduces penetration of UV rays: prohibits growth of algae
and clogging weeds.
- Aeration can be installed underneath the Armor Balls™ system
to ensure aerobic conditions are maintained.
- Reduce chemical consumption
- Unaffected by rain water

Technical Data
Armor Balls™ are manufactured with :
High Density Polyethylene (HDPE) -- Suitable for working conditions
up to 176°F (80°C). HDPE is recommended for all external
applications due to its enhanced resistance to freezing conditions.
Black, UV stabilizing additives prevent the degrading effects
of sunlight. HDPE is also recommended for demineralized water
and Chromic acid applications.
Ball diameter and surface coverage
There are different sizes and weights. PNW mainly distribute
Armor Ball™ having the following specifications :
- Diameter: 100 mm
- Average Weight: 44 g
- Number per sq.ft: 10
- Number per sq.meter: 116
The percentage of area covered by the balls is independent of
the ball diameter, being the ratio of a circle to the hexagon
which surrounds it. This equates to 91% of the liquid surface
area. The frictional contact points ensure that each ball remains
stable when subjected to increased liquid or air turbulence.
