Is my close system corroding? Is it in good or bad condition? Where do I start?

Start with a System Check.

This will provide you with an independent laboratory report on your system’s condition. With this information we can help you bring your system back to optimum performance and protect your key assets for the future


Local Authority Schools use Sentinel products to pre-clean and remove corrosion and debris prior to adding inhibitor and protecting the low temperature hot water system.
