Al 20 transforms high-frequency electric vibrations in mechanical vibrations of the same frequency through its transducer.

In swimming pools

AL 20 reduces about 1/3 or 1/4 the amount of chlorine used for disinfection.

In ponds

Thanks to ultrasonic waves algae have no chance of developing. If algae are already present, they die within 48 hours.
