Sentinel X400 Sludge Remover 1Ltr

Sentinel X400 Sludge Remover is a powerful central heating system cleanser formulated to remove black iron oxide sludge (magnetite), limescale, and other corrosion deposits that accumulate over time, reducing system efficiency and boiler performance.

Adding sludge remover before a full system flush restores heat output, reduces boiler noise, and extends the life of pumps, valves, and radiators. X400 circulates through the system at normal operating temperatures, breaking down stubborn deposits into suspension so they can be flushed away.

Key Features

• Removes black iron oxide sludge, limescale, and corrosion deposits
• Suitable for all central heating system types including sealed and open vented systems
• Compatible with all metals including aluminium heat exchangers
• 1 litre dose treats a typical domestic heating system
• Can be used with Sentinel X800 Rapid Power Flush Aid for heavily contaminated systems
• Works at normal operating temperatures — no powerflush equipment required for lightly sludged systems
• Use before applying Sentinel X100 Inhibitor to provide long-term corrosion protection

Application

Add X400 to the system via a radiator or magnetic filter, circulate for a minimum of one hour (longer for heavily sludged systems), then drain and flush the system. Follow with Sentinel X100 Inhibitor to maintain protection.
