Operators in the oil and gas industry value safety, reliability, environmental stewardship, and minimal downtime. These factors affect the productivity, viability and profitability of any production facility.  Relatherm Heat Transfer Fluids are designed and formulated with these requirements in mind. Our ultra-high temperature and high temperature heat transfer fluids lend themselves to typical process temperatures in the oil and gas industry while maintaining excellent thermal stability. We also feature some of the highest flash points in the industry, offering unmatched fire and explosion protection.

Relatherm Heat Transfer Fluid types are non-fouling, non-corrosive, and non-odorous. Our Extended Life Additive Technology confers an exceptionally long service life, thereby providing maximum uptime in oil and gas installations. Relatherm provides the highest protection possible against oxidation by virtue of our exclusive additive technology.

Oil and gas production facilities also take advantage of the 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.
