Sentinel offers a range of leave-in water treatments to protect heating and cooling systems against corrosion, sludge formation and limescale deposits.
These additives are also referred to as Inhibitors: they effectively inhibit (prevent) corrosion and scale formation processes.
Sentinel is a company with a clear goal: we offer water treatment products and services that provide the best lifetime protection for heating and hot water systems. Originally launched in the UK by Grace Dearborn in 1988 and subsequently a subsidiary of the leading multinational General Electric, Sentinel has operated independently since 2005, expanding its international reach and range of innovative solutions. As of 2021, Sentinel is owned by Aalberts N.V., and sits in the hydronic flow control cluster.
