SANILEC® systems take full advantage of our knowledge and experience in the design of offshore skid-mounted units, with strenuous area classification requirements.


SANILEC® systems generate sodium hypochlorite from seawater using an extensively field-proven electrochemical process. SANILEC® systems are the standard and preferred electrochlorination system for biofouling control in offshore and marine biofouling control as well as power and coastal applications. SANILEC® systems range in capacity from 2.8 to 47,620 lb/day (1.2 to 21,600 kg/day), per train.
