Heat Transfer Fluids play a vital role in many chemical and petrochemical plants. These plants manufacture all the things that support our way of life and everyday living. From gasoline to paint and cosmetics, Relatherm is one of the leading manufacturers of high-quality heat transfer fluids for all chemical and petrochemical industrial applications. Our engineers have decades of field experience working in refineries and chemical manufacturing facilities. So, we understand the non-negotiable requirements of thermal efficiency, precise process control, safety management, non-toxicity, process reliability, long fluid life and zero fouling.

Relatherm Heat Transfer Fluids outlast and outperform other industry fluids by virtue of their proprietary and exclusive additive technology. They are clean running, fouling-resistant, thermally stable, non-toxic, and non-hazardous.  More importantly, many of our thermal fluids feature the highest flash points in the industry. These can be very helpful with the prevention of fires and explosions emanating from heat transfer loops.

If you do not have a product selection in mind, our engineers will recommend the most the optimal heat transfer fluid for your application. They are also available to help troubleshoot your system and provide other technical support as needed. In addition, we provide system cleaners that can be used to restore and revive systems utilizing low quality heat transfer fluids. These systems are typically full of sludge and varnish with direct impacts on production outputs. Chemical and petrochemical manufacturing plants also take advantage of free fluid testing, analysis and interpretation offered through our complimentary Thermofluid Care ProgramOur 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.
