Heat transfer oil is a specially selected solvent refined mineral oil with low vapour pressure and excellent thermal stability and thermal conductivity. Our heat transfer oil range offers consistently high heat transfer performance and ease of circulation even when the system is started from cold.
If you are operating a pumped or conventional non-pressurised circulatory heating system, then these heat transfer oils are recommended as they are suitable for use in closed systems operating at bulk oil temperatures of up to 320°C. If used in an open system the maximum operating temperature for heat transfer oil would be 150°C.
