Aerzen Turbo G5plus, now with 13 sizes

New models AT75 and AT100 are now available

With the new generation Aerzen Turbo G5plus, AERZEN has designed the most compact and efficient turbo machine in its class. With the two new models AT75 and AT100, available immediately, the Aerzen Turbo G5plus portfolio has now been extended by another five to 13 sizes.

Aerzen Turbo G5plus is the most compact and efficient turbo machine of its class.

The Aerzen Turbo G5plus is available in all flow rates from 300 m³/h to 8,400 m³/h, and with a maximum pressure of 1,000 bar. The current selection of blower sizes ranges from the small AT 25-0.8 G5plus to the largest model AT 200-1.0 G5plus.

The series Aerzen Turbo G5plus lives up to its name, because it convinces through numerous advantages. The five new turbo machines have an extremely compact design and require very little space. Further outstanding features are the innovative AERZEN air foil bearings with double coating and the new multilevel frequency converter technology, which reduces the heat loss in the motor to a minimum and, consequently, improves the total efficiency significantly. Another advantage: an additional motor throttle or a sine filter, which has to be used with conventional frequency converters, is no longer necessary. The new air foil bearings represent a further decisive development thanks to double coating, consisting of Teflon and graphite. It impresses with increased temperature resistance and an increased service life of > 80,000 operating hours, regardless of start and stop cycles.

All advantages at a glance:

  • Increase of energy efficiency by up to 10% compared to conventional turbo technology.
  • Extended bearing life thanks to innovative AERZEN air foil bearings with double coating, maximum reliability, even under extreme operating conditions.
  • 100% oil-free.
  • Lowest maintenance effort, only regular filter change.
  • Extended fields of application at ambient temperatures up to 50°C.
  • Active surge protection by means of automatic speed increase.
  • Space-saving design.

AERZEN Technology at the L‘Aquarium in Barcelona

The spectacular Oceanario de L’Aquarium in Barcelona is considered the largest and most species-rich aquarium in Europe. With a diameter of 36 metres and a depth of 5 metres, it holds approximately 4 million litres of water. A few months ago, an AERZEN Delta Blower package was put into operation in the L’Aquarium. A large team of highly qualified professionals and cutting-edge technology enables to guarantee the health and wellbeing of over 11,000 animals at the L’Aquarium.

Around 6 million litres of seawater is needed to fill the 21 aquariums. This water is supplied continuously by means of controlled extraction in wells arranged specifically for this purpose. A sophisticated water purification system enables operation in a semi-closed cycle. Purification and filtration are required for a number of reasons. When leftover food, along with the excrement of each organism (with a high ammonium content), is biologically degraded, secondary chemical compounds form (nitrites and nitrates), which are very harmful to the occupants of the aquarium and must be removed. Final sterilisation of the water is required as a biological prevention measure towards the exterior of L’Aquarium.

The new AERZEN Delta Blower starts up in case of emergency, such as an electrical breakdown, and thus makes sure that the water runs out of filtration, and the fishes are provided with oxygen. The circulation of water is what generates oxygen. In addition, in an emergency, porous, pumice-like stones are put in the water to oxygenate the water. The AERZEN Delta Blower provides absolutely oil-free air according to ISO class. For the Aquarium application, it is a must: If the blower was operated with oil it would be fatal for the fishes.
