X500 Inhibited Antifreeze

What is the correct dose of Sentinel X500?

The dosage of Sentinel X500 Inhibited Antifreeze will depend on the level of frost protection required. One 20L pail of Sentinel X500 added to a typical domestic system of 8 to 10 radiator panels (which is a system volume of about 70L) will provide the minimum concentration of corrosion and scale inhibitor and also protection from freezing down to approximately -6°C.

Can I protect to temperatures lower than -6°C?

Protection from temperatures lower than -6°C can be achieved by adding extra Sentinel X500. Two 20L pails will provide protection in a typical system to -20°C. Further information is available upon request.

How do I get Sentinel X500 into the system?

In open Systems, dose via the F&E cistern, via a by-pass feeder or use a Sentinel Dosing Vessel. In sealed systems, if the system is empty, add to any convenient point before filling. If full, use a Sentinel Dosing Vessel to inject via the filling loop or other access point.

Can Sentinel X500 be used in areas with hard water?

Sentinel X500 is suitable for use in all types of municipal supply water, from very soft to very hard.
