Sterling - Model Granudos 45 -Integrated Dosing System
The Granudos 45 dosing system doses calcium hypochlorite directly from the drum. It uses acid that for the adjustment of pH in the pool water and additionally to avoid scaling within the dissolving equipment the acid is dosed within the system directly from the container.
Chlorine and acid are dosed separately at intervals to the dissolving system from where the very low concentrated chlorine solution is conveyed by a venturi nozzle to the pool water. Dosing manually/continuously or linked to any auto-control system with on/off output. Safety check and monitoring of flow, level, pressure and chemical empty. Switch off dosing in case of malfunction.
