Pharmaceutical Processing

Heat Transfer Fluid for Pharmaceutical Processing Applications

Pharmaceutical processing requires the use of a specific heat transfer fluid that is designed to work to the correct temperature for prolonged periods. Global Heat Transfer have worked with engineers in the pharmaceutical industry for over 25 years by supplying the correct heat transfer fluid and monitoring and maintaining thermal fluid for maximum operating efficiency.

Globaltherm™ heat transfer fluids are used for batch processing of pharmaceutical products. Heat transfer fluids with broad operating temperature ranges are required because chemical reactions take place at high temperatures and the crystallisation occurs at a lower temperature in order to make the final product. Globaltherm™ products are the preferred heat transfer fluid used in pharmaceutical batch processing.

Pharmaceutical processing requires the use of food grade heat transfer fluids in case of incidental contact with the product. Food grade heat transfer fluids are colourless, odourless, non-hazardous, non-toxic and NSF HT1 accredited.



A highly efficient, non-toxic, food grade heat transfer fluid that is safe for incidental food contact in food processing plants and pharmaceutical facilities

About Globaltherm® FG

Made from severely hydro-treated base stocks, Globaltherm® FG thermal fluidhas outstanding thermal oxidation stability allowing operation at high temperatures for extended periods. It is non-hazardous, non-toxic, water white and odourless.

Highly efficient non-fouling NSF HT-1, FDA and USDA-Certified food grade heat transfer fluid is specified in a broad variety of industrial process applications in addition to food processing.

Globaltherm® FG thermal fluid is a high efficiency heat transfer fluidspecifically developed for non-pressurised, indirectly heated, liquid phase heat transfer systems found in food processing plants, pharmaceutical operations and other “food grade” applications that require bulk temperatures up to 326°C (619°F). FG is a mixture of exceptionally pure HT hydrocracked base oils.

Globaltherm® FG is NSF certified for use in food and pharmaceutical processing

  • Globaltherm® FG thermal fluid is non-hazardous, non-toxic and odourless which means it requires no special handling and is not considered a “controlled substance” under United States OSHA, Canadian WHMIS or other work place regulations.
  • Globaltherm® FG is NSF HT-1 Accredited
  • The fluid is USDA CFR Title 21 178.3570 Compliant
  • The fluid is also USFDA21 CR Compliant


Globaltherm® J Heat transfer fluid is a superior high performance, energy efficient heat transfer fluid suitable for use in all kinds of industrial processes.
