Servo THERM S MEDIUM is used as a heat transfer medium in industrial applications operating at high temperatures. It has high viscosity index, excellent thermal and oxidation stability, low volatility and low vapour pressure to give long service life in well-designed heat transfer systems.It is used as a fluid medium in different types of heat transfer systems for direct or secondary heating in industry. It provides rapid heating and greater flexibility in heat transfer systems since they possess high specific heat and better thermal conductivity at all temperatures. It has high resistance to thermal cracking which maintains their heat transfer efficiency at different temperatures.It is used in heat transfer systems upto 3000 C.
