SAFE AND STABLE PLATFORM
All Polarcirkel cages are available with safe and sturdy walkway sections, as well as a strong built-in suspension system for sinker tubes.
state-of-the-art-machinery
STATE-OF-THE-ART MACHINERY
Sophisticated machinery produces pipes in a wide range of models. The cages are assembled by highly experienced and certified personell.

DECADES OF EXPERIENCE
AKVA group (Polarcirkel) invented the plastic cage in 1974, and has since then supplied more than 45,000 Polarcirkel cages.

DEVELOPMENT
The new "flagship", Polarcirkel 630, has 63 cm diameter on the floating pipe and up to 240m cage circumference.

UNIQUE FEATURES

UNIQUE FEATURES

The nets are easily connected to rugged PE plastic brackets. No metal parts that will create corrosion problems. The PE brackets have longer lifespan and are easy to clean.
New recessed connections inside the walkway for bridle, sinker tube or security rope for nets.
The Polarcirkel Sinker Tube consists of a 200-400mm heavy walled PE pipe filled with chain or wire rope at specified weight.
Rugged, galvanized net rods, hooks and railings

STRONG BRACKETS

Extensive use of PE (Polyethylene) in our PIM (Pressure Injection Moulded) brackets eliminates corrosion, minimizes expensive and difficult maintenance, and substantially increases cage lifespan compared to steel brackets. This is especially important in areas with high salinity, warm water temperatures and choppy seas.

STRUCTURAL STRENGTH

Polarcirkel brackets are superior in terms of structural strength, durability and UV resistance. This is especially important in high-energy offshore farm sites and areas with high UV radiation from the sun.

PREVENT ICING

For areas prone to icing, such as Norway and Canada, there is another critical advantage of the Polarcirkel PE brackets: it prevents icing. Icing is a dangerous safety issue for all floating structures, including cages. Heavy ice overloads the cage, reduces stability and jeopardizes overall cage integrity. As the name indicates, the Polarcirkel cages are well suited for extreme arctic conditions!

Cage Models

The most sold Polarcirkel models are the circular cages in 315, 400, 450, 500 and 630 mm floating pipes with circumferences from 60 - 240 metres.

PRODUCT SPECIFICATION

SAFETY

Polarcirkel offer an optimal secondary safety chain inside the outer floating pipe. This will serve as an unbreakable barrier in case the cage integrity is severely compromised. Keeping the chain inside the pipe leaves it out of the water until needed and maintains a clean exterior cage layout. All this makes the Polarcirkel cages the safest and most escape proof cages on the market!
