GRANUDOS 15-S5

For single pools

Dosing station for calcium hypochlorite granulate and acid for the disinfection of swimming pool water. Chlorine dosing directly from integrated hopper 15 kg. Acid is dosed into the system directly from the canister to correct the pH and to avoid scaling. Chlorine and acid are dosed separately in intervals to the dissolving system and are dissolved completely. Then the chlorine solution is conveyed by a venturi nozzle to the pool water. Dosing manually or linked to an external control system. All functions are permanently monitored.
