Pneumatic wave machine

Based on an invention by Professor Schuster and Dr. Boes, fluctuations in water levels are produced in wave chambers - open to the pool under water - by rhythmical changing of the air pressure. This principle produces a wave front transverse to the pool longitudinal axis. When the frequency is set appropriately the wave spreads to the flat section of the pool and rolls out in the form of surf. Bathers find our wave patterns very natural. 

The height of the wave should be between 0.8 and 1.2 m, preferably 0.9 m. This provides wave lengths of 10.0 to 15.0 m and periods of 2.5 to 3.1 seconds. 

The pool must not necessarily be rectangular but can be made up of different geometrical elements or display gently curved lines. Keep, however, to following rules to generate a beautiful wave:  

This configuration enables the swimming pool to be combined with a non-swimmer pool. By the way, swimmers in our pools can kick off against the wave chamber wall – the chamber apertures are mostly 0.7 m under water. 

The machine room should be dimensioned at least 3.0 m in width w and 2.0 m height h. The wave chamber necessitates – depending on the wave length – a width of 1.3 to 1.8 m.
The chambers must always be arranged at the immediate head of the pool. The compressors, on the other hand, can be located at the side or above the chambers. Such an installation can be used to operate several pools. 

One should work on a power of approx. 6.0 kW per meter of pool width to achieve a wave height of 0.9 m. It must, however, be noted that for calculating the operating costs waves are only produced twice an hour for 10 minutes in each case.
