Relatherm Heat Transfer Fluids manufactures a comprehensive suite of food-grade heat transfer fluids that are widely used for precise temperature control and indirect heat transport in food manufacturing and pharmaceutical applications. Our food-grade thermal fluids meet USDA and FDA requirements for incidental food contact (H1) as set out in 21CFR Section 178.3570.

Our heat transfer fluids are non-toxic, non-hazardous, non-corrosive, and odorless. They offer an exceptionally long service life, thereby providing maximum uptime to food and beverage manufacturers. Relatherm provides the highest protection possible against oxidation by virtue of our exclusive additive technology. In pharmaceutical kettles, chicken fryers, potato chip lines, and other food/pharma processing applications, our food-grade fluids provide non-fouling equipment operation and lower maintenance costs. Up to a maximum operating temperature of 340 OC/644OF, Relatherm food-grade heat transfer fluids maintain excellent thermal stability, with very low vapor pressures.
The Thermal Fluid Engineers at Relatherm are always happy to help with the selection of the most optimal food-grade heat transfer fluid for your application. They are also available to help troubleshoot your system and provide other technical support as needed. In addition, Relatherm manufactures a food-grade thermal fluid that runs simultaneously as a system cleaner. It is a great preventative maintenance solution for cleaning systems in place and preventing a buildup of varnish.
Food and pharmaceutical processors also take advantage of free fluid testing, analysis and interpretation offered through our complimentary ThermoFluid Care Program. Our Thermal Fluid Engineers are always on standby to offer expert advice on fluid selection, system troubleshooting, maintenance options and general technical support. Contact us today.
