Solar power plants utilize high temperature heat transfer fluids in heat exchangers to generate the steam that drives the power generating turbines. Relatherm Heat Transfer Fluids is a leading manufacturer of heat transfer fluids utilized by solar power plant operators. Our heat transfer fluids offer maximum resistance to oxidation.

As a result, they are non-fouling. More importantly, the thermal stability and longevity of our thermal fluids at elevated temperatures is well appreciated by solar plant operators. Apart from its non-fouling property and thermal stability, Relatherm Heat Transfer Fluids are non-toxic, non-hazardous, non-corrosive, and non-odorous.

Solar power plant operators 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.
