Asphalt
Heat Transfer Fluid for Asphalt (Bitumen) Manufacturing Applications
Asphalt manufacturing (also known as bitumen) requires the use of a specific heat transfer fluid that is designed to work to the correct temperature and to maximise product quality and yield.
Global Heat Transfer technical team have worked with engineers in the manufacturing and storage of bitumen for over 25 years, specifying and supplying the correct heat transfer fluid and testing and analysing the product frequently throughout the year. Global Heat Transfer also maintains thermal fluid for maximum operating efficiency.
Application
A superior high performance energy efficient heat transfer fluid suitable for use in all kinds of industrial processes.
About Globaltherm® M
Made from highly refined base stocks, Globaltherm® M thermal fluid has excellent thermal and oxidation stability allowing operation at high temperatures for extended periods.
The fluid also has efficient thermal conductivity and low viscosity, at the relevant operating temperatures, ensure high heat transfer rates requiring limited pumping energy.
Globaltherm® M heat transfer fluid provides:
- low vapour pressures at elevated temperatures
- greatly reduced evaporation
- vapour lock and cavitation eliminating the need for high pressure piping and equipment
Used fluid may be disposed of through a number of environmentally acceptable methods such as used oil recycling or heavy fuels burning.

Asphalt (bitumen) & Heat Transfer Fluid Systems
Heat transfer systems are a key part of asphalt manufacturing processes and storage facilities. Globaltherm® heat transfer fluids are widely used in the asphalt industry because of their high temperature stability.
Globaltherm® heat transfer fluids are used in asphalt facilities all over the world. Bulk terminals used to store and process asphalt use heat transfer fluid systems to maintain asphalt at specific temperatures. Roofing material manufacturing plants, which use asphalt as a raw material, require heat transfer fluid systems for heating the storage facility of asphalt and barges used to move asphalt maintain fluidity of their material with an on-board heat transfer fluid system.
