A non-toxic, concentrated heat transfer fluid for Air and Ground Source Heat Pumps. This product is designed to protect against corrosion, limescale and bacterial contamination, as well as frost protection from -14 to -34°C.
Dilute before use using mains water. In order to ensure adequate corrosion and biocidal protection, the minimum “in-use” concentration of the product is 33%. Maximum “in-use” concentration is 50%. Upon dilution Fernox HP-15c will provide frost protection according to the table below.
Concentration 33% 40% 50%
Frost Protection -14°C -22°C -34°C
Frost protection levels can be checked using a Fernox Refractometer. Existing heating systems should be cleaned of sludge and limescale deposits with a suitable Fernox Cleaner before adding Fernox HP-15c.
Fernox HP-15c is supplied in 25 litre drums.
