XCELTHERM® LV1 – Typical Properties

Biphenyl-free, non-hazardous alternative for high temp fluids with liquid or vapor phase to 700ºF (370ºC). Chemically similar to DOWTHERM™ A when used under 700ºF (370ºC). Recommended for Concentrated Solar Power Systems, PET production, Synthetic Fiber plants, Chemical Processing and many other applications that require a high temperature heat transfer fluid.
