BSZA 02 is a token-operated shower unit for wall assembly onto existing water inlets. Casing of the unit is manufactured out of stainless steel plate 2 mm thick and it is equipped with an anti-vandal thermostatic valve. It does not contain any dismountable parts, which reduces possibility of its damage, even wilful, to the minimum. The token box is secured by the electromagnetic lock. When the electromagnetic lock is closed, it is not possible to dismount the shower unit from its supporting frame.

A special shaped token is used for its activation. After inserting a token, water starts to flow for preconfigured period of time. The user operates the shower by pressing a START/STOP button. When last minute of the showering time is left, the user is given notice by interrupted water flow that the showering time is getting to its end.
