X300 from Sentinel has been specifically designed to remove fluxes, greases, metal fillings and harmful installation debris from the system and to prepare it for protection with an X100 inhibitor. It is only suitable for use with new systems (up to 6 months old).

Emulsifiers in the liquid assist in the removal of grease and oils from new radiators. Dispersants lift insoluble flux, metal fillings and dust from the system.

A single 1 litre bottle should be plenty to dose about 8 to 10 panels in your radiators. It can be added easily using a dosing vessel or the adaptor supplied. Ensure the system is filled before adding the X300.

After using X300, drain, then flush the system out before refilling and treating with X100 or X500.
