Transcal N is a high quality heat transfer oil possessing low vapour-pressure, good thermal stability, high specific heat and high thermal conductivity. The excellent thermal stability of the fluid gives long life, and the low viscosity characteristics ensure good heat transfer and ease of circulation at start up. Transcal N is used extensively throughout the South East Asia area with great success.

Main Benefits

– Long, maintenance free service

– Consistently high heat transfer performance

– Cost effective


Transcal N is recommended for non – pressurized, closed liquid – phase heating systems operating at bulk-fluid temperatures up to 320°C. It is employed in a wide range of manufacturing processes, and also for space heating drying, steam generation and as an alternative to electricity in applications such as die heating, and where products such as bitumen require to be heated at the time of application.

Operating Temperatures and Service Precautions

Transcal N is used for operation at bulk fluid temperatures up to 320°C and maximum heater skin temperature of 340°C. If these temperatures are exceeded, the fluid’s life is shortened by cracking and its characteristics are altered. It is recommended that fluid be sampled and analysed at least once a year, to ensure that they continue satisfactorily in service.
