Maintaining a Sodium Hypochlorite Generator: Annual Inspection Checklist

Your sodium hypochlorite generator keeps your rig or vessel’s cooling water systems free of biofouling. This system is essential—and expensive. Fortunately, routine maintenance and consistent check-ins on its performance will go a long way towards protecting your hypochlorite generator and its parts as well as your investment.  

However, it’s equally crucial to have an expert inspect your hypochlorite generator from time to time. Your annual inspection will serve as a baseline to help you keep tabs on your generator throughout the year, and also help your team flag issues for immediate maintenance to avoid unpleasant surprises with higher-cost repairs later on.
