Explore icy worlds at Hagenbeck

polar sea in Hagen- The beck Zoo reopened its gates again in summer 2012. Polar bears, walruses, seals and penguins now have a new home. The sophisticated water treat- ment technology, supported by Speck pumps, ensures that the animals have optimal living conditions. Large photo: Götz Berlik; small photos: Hagenbeck, Sylvie Bouchard, fotolia.com the polar sea it’s no With longer necessary to take a long and arduous trip to the North or South Pole. The arctic animal kingdom at Hagenbeck Zoo has had a new home since summer 2012. Visi- tors come within reach of the polar inhabitants: face to face with polar bears, with a diving walrus or an excit­ed penguin colony. A 750 m long path leads visitors through the polar sea in approximately an hour and a half with panoramic windows inside the facility allowing a fascinating in- sight into the underwater world. unrivalled, authentic arc- The tic animal kingdom has been created on a total area of 8000 m², 1200 m² of which is water surface. As well as polar bears, walruses, seals and penguins, puffins, guillemots and other types of seabird also belong to the icy world population. The latter are housed in their own seabird aviary.

Candan from the -based architect firm, Geising + Böker explained - 60% of rinse water is saved with the recool- ing extraction technique. Furthermore the Hamburg-based consultancy firm, GHP Hesse und Pokoiewski, invested considerable time and effort in the conceptual design of the water treat- ment technology in order to sustain the living conditions that the animals are used to. The company Wasser- technik Wertheim was then commis- sioned to install the water treatment technology. A total of five pools are available for the animals and four water cycles were installed to serve them, all of which are powered by Speck pumps.
