Solar-heat transfer fluid Type F, concentrate

The heat transfer fluids, based on propylene glycol, are refined with high-quality corrosion protection admixtures and stabilisers to prevent incrustations and hardness precipitations. The inhibitor system safely protects all metal materials that are normally used (except for galvanised steel) from corrosion and deposits.
