A large proportion of the seafood and fish consumed worldwide today comes from aquaculture, primarily as an alternative to wild fishing and to protect overfished stocks. Fish and seafood are produced efficiently and with high yields in cages or tanks, meaning that aquacultures are playing an increasingly important role in the global food supply. This is because demand and therefore the market are growing continuously, meaning that more and more aquaculture facilities are being built.

Various components must work together optimally to ensure the health of the farmed marine animals and their food supply. This is usually done using automatic feeders and water mills that constantly transport air into the water so that shrimp, for example, are sufficiently supplied with oxygen. All of this requires a safe and reliable energy supply. For this reason, LAPP, the global market leader for integrated solutions and branded products in the field of cable and connection technology, has developed the new ÖLFLEX® AQUA 510 P, an extremely robust connection cable especially for aquaculture.

Can be used in all climate zones

The ÖLFLEX® AQUA 510 P is particularly suitable for use in harsh weather conditions, such as those found in oceans. The robust, ozone-resistant, halogen-free and plasticiser-free PUR cable can easily withstand the excretions of marine animals as well as UV radiation, mineral oil-based lubricants, ammonia and other chemical influences. Thanks to the reinforced, cut and notch-resistant heavy-duty cable design, the product can also withstand rough handling on site. A special feature is its particularly smooth, non-porous outer sheath surface, which can reduce algae and mussel infestation and is easier to clean. Their low-capacity core insulation is suitable for long, loss-free transmission paths with fixed installation and occasional movement. "Up to now, standard rubber cables have mainly been used in the aquaculture sector," says LAPP Product Manager Frank Hörtnagl. "However, these pipes are usually not particularly durable and can become brittle in salt and, above all, waste water. Shell limestone could settle more easily in the pores of the rough outer sheaths, which meant that mechanical cleaning had to be carried out again and again, which can also have a negative impact on the service life of the pipes. With the ÖLFLEX® AQUA 510 P, we have developed a pipe that can easily withstand all these influences."

As fish and seafood are farmed in all oceans, the line is designed for use in all climate zones (subpolar, temperate, subtropical and tropical) and is standardised for use in fresh water up to 10 m deep and 40° C water temperature. In addition to aeration systems and automatic feeders for aquacultures, other areas of application include moorings in harbours, fountains, construction sites, event technology and agricultural applications.
