Electrolysis plants of the types CHLORINSITU® II produce sodium hypochlorite with a concentration of 5 g/l. For this process, a saturated solution of sodium chloride is produced in a salt dissolving tank included in the scope of delivery. This solution is then diluted correspondingly and electrolysed in a membrane-free cell. The resulting solution is collected in a storage tank and from there metered with separate metering pumps as needed. Because of the moderate pH value of approx. 9, the pH value of the treated water is significantly less affected than when using commercially available sodium hypochlorite (pH 12-13.5). The generated hydrogen is diluted with fresh air through an ATEX-certified ventilator and discharged safely. Both the salt dissolving and the diluent water come from a softener integrated in the plant. Thus, lime deposits can be prevented and a long service life of the electrolytic cell can be ensured.
The plants are controlled with a modern PLC with large, illuminated display and integrated modem for remote diagnosis and troubleshooting.
