High performance, durability and escape prevention

The non-fibre Polarcirkel EcoNet has a very hard surface that resists marine fouling and makes it easy to clean in the water. Due to the very low water drag resistance, the EcoNet also ensures maximum water flow to the fish. This has resulted in some of the best ever production results in large scale salmon farming, such as higher SGR, lower FCR, lower mortality and higher fish harvest quality.

The EcoNet is certified under NS 9415:2009 to stay in the water for up to 14 years. This eliminates costly net changes and reduce the risk of net handling. Polarcirkel EcoNet has also proven very resistant to predator attacks. Should damage to the net occur, the semi-rigid structure has proven to have self-closing properties that prevent fish escape.

A NET YOU CAN TRUST

Superior strength, durability and quality

EcoNet is approved for fishfarming use according to Norwegian Standard 9415 - NS9415, to stay in the water for up to 14 years. The Polarcirkel EcoNet is made from very strong but light weight PET, (Polyethylene Terephthalate).

A NET YOU CAN TRUST

Superior strength, durability and quality

MORE THAN 20 YEARS LIFESPAN

The Polarcirkel EcoNets is made from very strong but light weight PET and has a 20-year lifespan. The nets can also be used as rock slide nets.

WITHSTANDS ROUGH CONDITIONS

The Polarcirkel EcoNets are made for rough, daily use. The smooth monofilament PET and the semi-rigid structures ensures mimimum water drag resistance and prevents overall net shape collapse.

EFFECTIVE ESCAPE PREVENTION

The EcoNet has some superior characteristics, including: being virtually escape proof and will prevent species like cod who often can damage regular nets.

EASILY HANDLED

EcoNet can almost be handled in similar ways as a nylon net. This includes drying up during harvest, fastening to the pens or attaching sinker tubes.

SUITS CIRCULAR AND SQUARE PENS

The upper section have vertical walls with a 1 m jump-net up top and the bottom is normally cone shaped.

PREDATOR PROTECTION

The EcoNet is predator proof and is also used as shark net. The semirigid structure will keep the net shape intact.

If overloaded, EcoNet stretch about 60-70% before it finally breaks.

In comparison, nylon stretch about 40% before it breaks.

The shape of the EcoNet wire mesh is designed to remain intact if a single wire is cut. This means the mesh will remain stable and the shape intact with minimum negative effect of the strength of the net pen structure. The Polarcirkel EcoNet is made from very strong but light weight PET, (Polyethylene Terephthalate).

Polarcirkel EcoNet is available in three different mesh sizes. Small is suitable for 150 g Atlantic Salmon smolts and up:

PENS NETS

AKVA group offer several types of nets for your pens. Both traditional and proven fibre nets (mainly nylon) made by Egersund Net in Norway, as well as non-fiber EcoNets (solid PET wire).
