  •     Protects all system metals
  •     Ensures optimum boiler efficiency
  •     Prevents boiler noise
  •     Prevents pin-holing
  •     Helps prevent the formation of hydrogen gas
  •     A simple test kit is available to check levels


For best results, systems should be cleansed and flushed in accordance with BS7593:2006 new systems and those up to 6 months old with Sentinel X300, existing systems with Sentinel X400 or Sentinel X800 Jetflo.

Sentinel X500 Inhibited Antifreeze 5 Ltr Dosage:


The dosage of Sentinel X500 inhibited antifreeze will depend on the level of frost protection required. 20L of Sentinel X500 antifreeze added to a typical domestic system up to 10 radiators will provide the minimum concentration of corrosion and scale inhibitor and also protection from freezing down to approximately -6°C. 40L will provide protection to -20°C.
