HEAT TRANSFER OIL Series
 

Description

These oils are blended carefully with selective base stocks having good natural thermal stability to prevent catalytic thermal breakdown in service. Base stock components are chosen in such a manner that these will provide resistance to evaporation at high temperature. These oils also have high viscosity index so that any appreciable change in viscosity does not affect heat transfer efficiency of the oil.
 

Applications

  • PSO Heat Transfer oils are chosen for high temperature operation because of their good thermal stability and are used both for heating systems in process industries and viscosity baths.
  • In air excluded systems, these products are satisfactorily performed up to a temperature of 300°C. Localized temperatures may be avoided to prevent thermal breakdown of the oil which can lead to carbon formation.
     

Benefits

  • Bulk temperature could be increased upto 300°C under carefully controlled condition.
  • Good rust protection.
  • Good oxidation stability.

PSO HEAT TRANSFER OIL EXCEL-32
 

Description

PSO Heat Transfer Oil Excel is blended with highly refined base stocks having strong inherited resistance to oxidation and thermal breakdown while operating at elevated temperatures. Base stock components are selected to provide resistance to evaporation at high temperatures. The oil has high viscosity index so that any appreciable change in viscosity does not affect heat transfer efficiency of the oil.
 

Applications

  • PSO Heat Transfer Oil Excel is applicable to use in indirect heating and cooling installations in industrial processes operating at maximum bulk oil temperature 320°C.
  • Localized heating may be avoided to prevent thermal breakdown of the oil which can lead to carbon formation.
     

Benefits

  • PSO Heat Transfer Oil Excel is suitable for high temperature operation because of their excellent thermal stability and resistance to sludge formation.
  • The product is applicable for heating systems in process industries, heat exchanger and viscosity baths.
  • Good rust protection and resistance to thermal cracking due to oxidation.
  • Excellent oxidation stability ensures longer service life and minimize operating cost.
