Inhibitor for protection against corrosion and limescale Sentinel X100, 1L
Sentinel X100 1L – corrosion and limescale inhibitor
Sentinel X100 is a high-performance inhibitor designed to provide long-term protection for central heating systems against corrosion and limescale formation. It helps protect boilers, radiators, heat exchangers, pipework and other heating system components while helping the system maintain efficient operation.
Sentinel X100 is formulated for multi-metal heating systems and protects all common system metals. It is particularly effective in protecting aluminium components and modern heat exchangers. Its formulation helps stabilise the pH of system water and reduce conditions that can accelerate corrosion.
The inhibitor is suitable for use with both hard and soft water and also helps prevent hydrogen gas formation and system noise associated with corrosion and deposits.
Main advantages
- Protects heating systems against corrosion.
- Helps prevent limescale formation.
- Protects radiators, boilers and heat exchangers.
- Particularly effective in protecting aluminium components.
- Helps stabilise system water pH.
- Helps prevent hydrogen gas formation.
- Suitable for multi-metal heating systems.
- Suitable for hard and soft water.
- Helps maintain optimum heating system efficiency.
- Remains in the system for long-term protection.

Application
1 litre of Sentinel X100 treats up to 100 litres of system water. This is equivalent to a typical domestic heating system with approximately 8–10 radiator panels. Larger systems should be dosed proportionally according to system water volume.
In sealed systems, if the system is empty, the product can be added at a convenient point before filling. If the system is full, the inhibitor can be introduced through the filling loop or another suitable access point.
For optimum results, new or contaminated heating systems should be properly cleaned and flushed before adding Sentinel X100.
Not intended for use in potable water systems.
