Applications
Shell Thermia Oil D is a higher viscosity heat transfer fluid for use in indirectly heated closed heat transfer systems. It is based on carefully selected highly refined mineral oils chosen for their ability to provide superior performance in heat transfer systems.
- Industrial heat transfer systems – For use in closed heat transfer systems used in chemical and process plant, textile manufacture etc. where the oil is circulated in a pumped system operating under atmospheric pressure with or without an inert gas blanket.
- Shell Thermia D can be used in high temperature continuous heat transfer equipment with the following application limits:
|
Max. film temperature |
340°C |
|
|
|
|
Max. bulk temperature |
320°C |
