Pennine Heat Transfer Oils are based on specially selected solvent refined mineral oils with low
vapour pressure and excellent thermal stability and thermal conductivity. They offer consistently
high heat transfer performance and ease of circulation even when the system is started from cold.
Applications
These products are recommended for both pumped and conventional non-pressurised circulatory
heating systems. They are suitable for use in closed systems operating at bulk oil temperatures of
up to 320oC. If used in an open system, the maximum operating temperature would be 150oC.
