X500 Inhibited Antifreeze - 189206 Provides protection against scale and corrosion in all types of indirect heating systems, including those containing aluminium components, whilst preventing freezing. It is effective at preventing hydrogen gas production.
The product is not suitable for heat transfer circuits of solar energy collector panels in which temperatures may exceed 200C or be subject to periods of stagnation.
For best results, systems should be cleansed and flushed in accordance with BS7593: new systems and those up to 6 months old with Sentinel X300, existing systems with Sentinel X400 or Sentinel X800 Jetflo.
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 will provide the minimum concentration of corrosion and scale inhibitor and also protection from freezing down to approximately -6°C. Two 20L pails will provide protection to -20°C.
