Ready for a vacation? – „Tropical Islands“ are close by

For many years, Mr. Colin Au, successful owner of a cruiseline, had brought tourists to tropical and subtropical regions, especially in the Pacific. Recently, the ambitious businessman from Malaysia, together with other investors, footed a bill of 70 million Euros to bring the Tropical Islands to Germany.

Europe’s only tropical paradise was opened in December of 2004 south of Berlin in the world’s largest self-supporting hall. Originally intended for the assembly of cargo dirigibles, the location now is home to an attractive recreational area of 6,6, hectares (66.000 square meters) in seize, featuring shows, entertainment, swimming, sports activities, a children’s club, beach parties, restaurants and souvenirs.

The impressive hall, 360 meters long, 210 meters wide and 107 meters high, presents an authentical tropical vegetation with 500 different plants and allows insights into the cultures of Brazil, Bali, Thailand, Malaysia and Kenya. Well-known interior decorators, landscape-gardeners and botanists have been won for this project.

Approximately 5 million people living within an hour’s driving distance are the potential visitors of the Tropical Islands resort. 850 employees are waiting to take care for them, 24 hours a day and 7 days a week. The maximum daily capacity runs up to 7.000 visitors. This already gigantic business is about to grow further by adding an outside recreational area of 500 hectares (5.000.000 square meters).

The resort has its own power station with a capacity of 2 x 3,5 MW which supplies heating and energy. Thus, an overall air temperature of 25-28 degrees Centigrade is maintained, in some parts even up to 35 degrees. The temperature of the 6.000 cubic meters of water is 28 degrees (in the „South Sea“) or 32 degrees (in the „Lagoon“). The tropical ocean’s surface amounts to 4.000 square meters.

Pumps systems from Lowara ( are used for water supply and water pressure. With its offer of pumps and pipe systems, the company Alther from Greifswald won the contract. The Krausnick water works are in charge for supplying the Tropical Islands resort. They obtain their drinking water from deep wells.

From a 7 kilometers long water pipe and a booster unit, GT 30 HV SV 4602 F75T series, the water is pumped under constant pressure into two intermediate reservoirs with a capacity of 300 cubic meters each.

Tropical Islands’ need of 180 cubic meters of drinking water per day comprises also the daily refilling of the pools which is demanded by sanitary regulations. This daily demand is supplied by means of a Druckerhöhungsanlage, GT 40 HV SV 6603/1 F 150 T/ series, with a constant pressure of 6 bar. Both Druckerhöhungsamlagen are monitored by a Hydrovar® control system which, by way of its rpm control, operates in a very energy efficient way.

The Hydrovar® control module makes it possible to compensate for varying levels of water demand by changing the rpm. The systems are laid out in such a way that they can cover the needs of the future outside expansion. After a certain running time the operational pumps are exchanged automatically so that the load is equally distributed among the reserve pumps as well.

The water supply system is integrated into the central control system of the Tropical Islands resort through a collective malfunction notice. The systems controls regarding pump-in-operation notice, running time, water pressure and water volume, are computerized and operated by the employees.
