X100 Inhibitor

Will Sentinel X100 protect my system if it is filled with softened water?

Softened water, particularly those from household softeners not conforming to BS EN 14743, is not suitable for filling a domestic central heating system unless the water is treated with a high quality corrosion inhibitor. Unlike many other products on the market, Sentinel X100 has been especially designed to cope with all types of supply water, even softened water and affords complete protection.

How long does Sentinel X100 last in the system?

Once the correct amount of Sentinel X100 has been added, it remains in the system indefinitely, providing ongoing protection. Depletion only occurs by dilution, e.g. when the system is topped up after removing, emptying and then re-connecting radiators during house decorating. It is necessary to check the concentration of Sentinel X100 using the Sentinel Test Kit after replacement of system components (boiler, radiators etc) and replenished as necessary.

Can I overdose my system with Sentinel X100?

It is not necessary to add more than 1 litre of Sentinel X100 to a typical domestic system of 8 to 10 radiator panels (which is a system volume of about 70L). However, exceeding this dose, by even as much as several percent will have no negative effect on the system... only on the purse!!

Is Sentinel X100 compatible with other brands of treatment products?

The effects on system protection and function of system components cannot be predicted when adding Sentinel X100 to a system already containing other chemical inhibitors. Therefore, it is not recommended to mix Sentinel X100 with other inhibitor products.

Can I use Sentinel X100 if I have aluminium components in my system?

Yes!! Sentinel X100 was specially developed to protect multi-metal systems, including those comprising aluminium components. Sentinel X100 protects aluminium by ensuring and maintaining neutral pH conditions.

My water pH level is about 8.0 - will the Sentinel X100 increase this?

No. Sentinel X100 contains what is known as a pH "buffer". These ingredients in the formulation are designed to actually control the pH level in the water at neutral (approx. pH 7.0), even if the pH level of the incoming water is less than 6.5 or more than pH 8.0.

What dosage should I use?

1 litre of Sentinel X100 is sufficient to treat a typical domestic system of 8 to 10 radiator panels. Larger systems should be dosed with 2 litres.

Is there a Material Safety Data Sheet or a COSHH Data Sheet?

Sentinel X100 is non hazardous and zero COSHH rated. Both the Material Safety Data Sheet and the COSHH Data Sheet are available upon request.

Can I use Sentinel X100 in a Primatic Cylinder?

No.
