Nextherm - Nextherm 315

NEXTHERM 315 is a economical, highly thermally stable heat transfer fluid is ideal for applications up to 315°C. This improved thermal capacity and conductivity increases system performance by enhancing the heat transfer capability. NEXTHERM 315 combination of high-quality base fluids and additives provides excellent resistance to oxidation and thermal degradation. The non-toxic and non-hazardous formulation is safe for workers and the environment and can be disposed in the same manner as used motor oil.
