OSEC® L hypochlorite generation system

The OSEC® L system provides a stable disinfection solution on-site and on-demand.

​An inherently safe alternative to chlorine, sodium hypochlorite and calcium hypochlorite, the OSEC system does not require handling of any hazardous chemicals. The generator produces a dilute hypochlorite solution <1.0 wt% concentration using saturated brine (salt), water and electricity in an electrochemical process. With an embedded process controller the system is fully automated and can work in batching or direct feed operation modes.
