Covex^® Hexagonal Floating Cover

The Simple Solution for Tanks and Lagoons

Covex^® is a hexagonal floating cover: individual HDPE tiles that float on the surface and nest together to cover up to 98% of the water. IECʼs newest floating cover system controls algae and odors on tanks and lagoons of all sizes and shapes, including those with variable water level changes, irregular water lines and multiple pipe penetrations. Covex^® is easy to install, requiring no special skills or equipment.

A Hexagonal Tile Cover for Tanks and Lagoons

Each Covex^® tile is a hexagon of industrial strength HDPE that is pre-filled with water for ballast. On the water, the hexagonal cover tiles nest edge to edge, with no expensive engineering design to work out. Because the tiles are separate pieces, the cover follows changes in the water level and closes in around pipes and other penetrations. The ultra-low profile of Covex^® provides superior wind-resistance with coverage up to 98% of the water surface. Covex^® floating cover is a superior alternative to more commonly known products like pond balls, bird balls, and barrier balls.

Benefits

Evaporation Reduction

Covex^® minimizes water loss due to evaporation by covering up to 98% of the water surface and reducing the evaporative effects of wind and wave action.

In addition, shading of the water cools the water surface temperature which further reduces evaporation.

Algae, TSS and Biofilm Reduction

Blocking sunlight from penetrating the water column eliminates photosynthesis which algae and aquatic plants rely upon for growth and establishment.

The result is improved water quality and disinfection.

Covex^® can eliminate the need for expensive alternative methods such as chemical dosing and mechanical separation equipment.

Odor Reduction

Elimination of the air-to-water interface reduces transmission of odors emitted from the water surface.

The nesting arrangement of the cover tiles is a quick, and easy way of covering a water surface without expensive engineering designs and installation requirements.

Wildlife Deterrent

Covex^® can also be used as a deterrent to waterfowl and other wildlife by “hiding” the visible liquid surface.

The cover provides an appearance of a non-liquid, solid, monolithic surface, thus deterring wildlife from the water source.

STABILITY and Wind Resistance

The hexagonal cover tiles are ballasted (pre-filled at the factory) with water in the central chamber to give it stability in all operating conditions.

The low-profile aerodynamic design has a low center of gravity providing exceptional wind resistance and stability.

Recyclable, Low-Plastic Design

Covex^® tiles are made of HDPE and are recyclable.

Manufacturing process uses energy from renewable sources.

Covex^® uses the least amount of plastic on the market when compared to similar floating cover products.

Frequently Asked Questions

What is a hexagonal floating cover?

A hexagonal floating cover is made of many separate six-sided tiles instead of one sheet. The tiles float on the liquid and nest together like a honeycomb, so the cover takes the shape of whatever tank or lagoon it is in. You may also see it called a hex tile cover or hexagonal tile cover. Covex^® is the hexagonal cover IEC supplies.

How big are Covex^® tiles, and how many do I need?

Each tile is 6 inches across from flat side to flat side and 2.1 inches high. It takes about 50 tiles to cover a square meter, or about 4.6 tiles per square foot. Contact IEC with your tank or lagoon dimensions for a tile count.

How much does Covex^® reduce evaporation, algae and odors?

Covex^® reduces evaporation by 96% (plus or minus 2%), reduces algae formation by over 90%, and reduces odors and emissions by over 90%.

How is a Covex^® floating cover installed?

Covex^® requires no special skills or equipment. The tiles nest into place on the water surface without expensive engineering designs or installation requirements. The video above shows an installation.

Does a hex tile cover work when the water level changes?

Yes. Covex^® is designed for tanks and lagoons with variable water level changes, irregular water lines and multiple pipe penetrations.

What are the hexagonal cover tiles made of?

Industrial strength HDPE with UV and antioxidant additives. Each tile is pre-filled at the factory with water in its central chamber, which gives it ballast and a low center of gravity. The tiles are recyclable.

What temperatures can Covex^® handle?

Covex^® tiles are rated for operating temperatures from -40°F to 185°F.

How long does a Covex^® cover last?

Covex^® carries a 10-year manufacturerʼs warranty and has an expected lifespan of 25 years or more.

How much of the surface does Covex^® cover?

Up to 98% of the water surface. That coverage is what blocks sunlight, cuts evaporation and reduces odors.

Where are hexagonal tile covers used?

Municipal wastewater, mining, fracking, agriculture, chemical plants and power plants, on both tanks and lagoons.
