Caraflow CHS Central Heating Antifreeze has been specially developed, Carlfow CHS is a direct like for like/direct equivalent and replacement for the Fernox Alphi11.

Caraflow is a high temperature antifreeze for boilers, central heating and mixed metal hot water heating systems – Suitable for all applications including Underfloor, radiators and old or new systems. This has been especially formulated for use as a Non Toxic heat transfer fluid for use in Hot Water Heating Systems.

Caraflow has an LD50 toxicity rating (Oral Rat) of >15,000 mg/kg ofbody weight (bw) = ‘Relatively Harmless’. As confirmed by the Hodge & Sterner Scale.

Caraflow CHS contains synergistic corrosion inhibitors to protect metals commonly found in such systems. It has been tested in accordance with BS5117 and found to meet BS6580 and ASTM D1384 corrosion standards. It also contains scale and biological inhibitors to help preventfouling -thus promoting long operational life and high thermal efficiency.


As per BSRIA guide BG 29/2012 all pipe-work systems should be clean andfree from biological contamination and debris prior to commissioning.To minimise corrosion air ingress should be minimized. A pressurised systemis best.Determine the total system volume and add ThermaFlow TPF to the system according to the minimum operating temperature required.The minimum dose of Caraflow CHS should not be less than 25% of the system volume and the maximum does not normally exceed 60%. We recommend the use of deionised, distilled or UltraPure™ water for this dilution. Avoid water containing high levels of calcium salts or Chlorides [Cl-].


Caraflow CHS mixtures arereadily biodegradable (90% overten days) and will not remain in the environment orbio-accumulate.
