Improved and better performing R700 Sanitiser & Biocide from Sentinel

Improved and better performing R700 Sanitiser & Biocide from Sentinel

The new R700 Sanitiser & Biocide is a more stable better performing non-peroxide biocide giving the installer and end user greater peace of mind. Still supplied in 1 litre bottles and available from stock. The new formulation of R700 is still compatible with the existing R500C & R600 heat transfer fluids.

With the technical improvements Sentinel have made to the R700 a new test kit will be required to test the biocide levels in a system (the old test kit will not work with the new revised formulation of R700).

Normal boiler systems do not generally need to be sanitised with R700 because they operate at temperatures well above 60C and therefore there is a general pasteurisation effect. However, many biomass boilers do not run on a regular basis or they are so big that the temp in some parts of the system remains low, e.g. underfloor heating.  – If you think this is the case then using R700 to sanitise is a wise precaution… if in doubt add R700!

  • Sanitizer & Biocide
  • Typical fill is 1 litre bottle for 300L (new system)
  • 3 in 1 advantages
    • Pre-treatment steriliser
    • Ideal as a system protector if the collector pipes/vertical probes are to be commissioned at a later date to maintain a sterile environment
    • Can be added to a system where there exists problems caused by the growth of organisms such as bacteria & fungi. Caused typically by the degradation of thermal fluids or blockages in the pipework system causing unpleasant smells and corrosion of heat exchangers & manifolds etc.

Sentinel R700 New Formulation



As per BSRIA guide BG29/2012 and Building Regs PART L all pipework should be cleaned and sanitised to remove all physical debris and biological growth prior to the installation of a thermal fluid.

Kilfrost GEO is also available pre-diluted with de-ionised water to the required level of freeze protection.
