Inhibitor for protection against corrosion and limescale Sentinel X100RD EXPRESS 300ml

Sentinel X100RD EXPRESS 300 ml – corrosion and limescale inhibitor
Sentinel X100RD EXPRESS is a high-performance inhibitor designed to provide long-term protection for closed heating and cooling systems against corrosion, limescale formation and hydrogen gas generation. It helps maintain efficient system operation while protecting radiators, boilers, heat exchangers, pipework and other system components.
Sentinel X100 is suitable for multi-metal systems containing components made from steel, copper, cast iron and aluminium. It is suitable for use with hard, soft and artificially softened water.
The Rapid-Dose / EXPRESS 300 ml pressurised container allows the inhibitor to be added quickly and conveniently to the heating system. One 300 ml dose treats a system containing up to 100 litres of system water. For larger systems, the quantity should be increased proportionally.

Application
One 300 ml container treats a system containing up to 100 litres of water. For larger systems, increase the dose proportionally to the system volume.
The Rapid-Dose product is introduced into the heating system through a suitable connection point in accordance with Sentinel instructions. The system should be cold during dosing. If system pressure exceeds 2.3 bar, the pressure should be reduced before dosing.
For contaminated or older heating systems, cleaning with a suitable Sentinel system cleaner is recommended before adding the inhibitor.
