NOLTA plugs save lives

The shark is only about three meters away from him and the pulse of Sven Bergemann accelerates. Two meters. One meter. Such a close encounter would never have been thought possible by the German tourist in Australia. Then the shark turns away. Too bad.

Sven Bergemann is one of millions of visitors who are drawn to the fifth continent every year. For those who do not want to dive or snorkel, huge aquariums offer insights into the wonders of the ocean. Visitors such as Sven Bergemann can experience superlative aquatics along the entire eastern coast of the state. What remains hidden to most, however, is the immense technical effort behind the scenes. Daily cleaning of the basins is only a small part of the mission to keep the magnificient and sometimes rare marine life alive.  Beneath or behind the display basins are settling tanks, trickle filters, miles of pipes and countless pumps.

Therefore, a large part of the technical staff experiences an aquarium completely differently than the visitors - namely as an endless labyrinth with stifling air and condensation dripping from salt-encrusted pipes. Meticulously, the engineers keep an eye on the power supply and pumps. They know that if they fail, the lives of the fish will be at risk.

A German technician specializes in aquaristic research for reef fish and has been working for several years on the east coast of Australia for various institutions. Again and again he had to observe that the water quality of the pool deteriorated and fish died because pumps had failed unnoticed. The diagnosis was simple: The pumps lacked a motor protection plug. In the whole country.

As a technician, the German had the rescuing idea when he discovered NOLTA plugs on the compressors for diving bottles: If NOLTA plugs were also available in Australia, you could easily equip the aquariums on the east coast with them.
With success: Now NOLTA plugs protect the pumps against overload, short circuit or wrong direction of rotation. The technology works much more reliable. If a pump actually overloads, it is enough to simply switch the plug back on instead of connecting a new pump. Thus, the investment in the NOLTA plugs also has had a positive effect on the bottom line of the aquariums.

However, the investment has mostly a positive effect on the fish since the pumps have routed thousands of cubic meters of water per day through various filters in order to eliminate metabolic waste and supply oxygen.
