Application and Dosage
The recommended ‘in-use’ concentration of Protector MB-1 is 4%. One pack i.e. 4 litres will protect an average system (up to ten radiators). For open vented systems add via the feed and expansion tank. For sealed systems add via the radiator or filling loop using a Fernox Injector. In single feed indirect cylinders, e.g. “Primatic” or similar, potable water chemicals must be used. We recommend untreated or sludged systems are thoroughly cleaned and flushed in accordance with BS7593 and Benchmark using Fernox Cleaner F3, before treating with Fernox Protector MB-1, as existing debris can damage the installation.
Protector MB-1 is a blend of inorganic and organic corrosion and scale inhibitors and biocide. Protector MB-1 is a proven corrosion inhibitor, which is effective at preventing limescale formation in domestic central heating systems.
