A concentrated heat transfer fluid for Air and Ground Source Heat Pumps based on ethylene glycol. This high performance product is designed to protect against corrosion and limescale, as well as frost protection from -10 to -33°C.
Dilute before use using mains water. Deionised water (demineralised) or artificially softened water is also suitable, if preferred. To ensure adequate corrosion protection, the minimum ‘in-use’ concentration of the product is 25%. Upon dilution Fernox HP-EG will provide frost protection according to the table below.
Concentration 25% 30% 35% 40% 45% 50%
Frost Protection -10 °C -14 °C -18 °C -22 °C -28 °C -33 °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-EG.
Fernox HP-EG is supplied in 20 litre drums, 205 litre drums and 1000 litre IBCs.
Keep out of reach of children. Do not mix with other chemicals. For further information on handling and safety, please refer to the Safety Data Sheet (SDS).
