OASE Fountain Technology / Lake Management – Catalogue
Nozzles
Controllable
In musical water organs or other spray fountain
installations with dynamic elements water becomes
lively with help from Vario switch systems.
This water switch is combined with a suitable nozzle
and switches between two outputs – similar to a 3/2-
way valve – almost without pressure loss and without
water hammer effects in the lines. Normally one of
those outputs is used as a pure bypass, however a
second nozzle can also be mounted.
The air supply for alternately switching atmospheric
pressure on and off is executed via the telescopic
tube using the so-called Coanda effect. Switchover
time is flow dependent and times of 0.1 s are certainly
achievable.
