Heat Transfer Oil


Heat transfer oils are produced with well-refined mineral base oils based on high thermal and oxidation stability and with effective additives that further enhance this property. 

Their heat transfer coefficients are high. No thermal degradation, sludges and deposits occur between -10 °C and 320 °C, which are the recommended usage temperatures. 

They are used in all types of industrial closed-system hot oil boilers. Their extraordinary thermal and oxidation stability enables working for a long time without any problem.
