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.
