Gulf Therm 32 is premium quality heat transfer oil intended for use in closed indirect heating systems. It is formulated from highly refined base stocks to provide excellent oxidation stability and resistance against thermal cracking. It possesses high specific heat and thermal conductivity to provide more rapid heat dissipation and its ability to flow rapidly at low temperatures ensures quick circulation at start-up and reduced risk of local over-heating. Although Gulf Therm 32 is thermally very stable and is capable of offering extended service life without viscosity increase or deposit formation, it should be realised that the working life depends to a considerable extent on the effectiveness of the measures taken to exclude air. Gulf Therm 32 is primarily intended for use in enclosed and sealed heating systems where the maximum bulk oil temperature does not exceed 315 oC.
