NORC HTO-SYN 25 is a high quality synthetic heat transfer oil intended for use in closed indirect
heating systems with expansion tanks temperature up to 350°C. It is easy to dispose, since its
formula is non-toxic, and as well non-corrosive to aluminum, steel, and copper brass or bronze.
NORC HTO-SYN 25 is precisely designed with exceptional resistance to thermal cracking and decomposition
that enables the oil to perform well up to a maximum bulk oil temperature of 350°C with minimal interference
with heat transfer capability.
NORC HTO-SYN 25 has a superior low temperature fluidity to ensure quick circulation at start-up and reduced risk of
local over-heating. Furthermore, it has a high specific heat and thermal conductivity.
  • Non-toxic formulation for easy disposal
  • Non corrosive to aluminum, steel, copper, brass or bronze
  • Minimizes deposit formation and viscosity increase
  • Extended service life and reduced downtime
  • Exceptional resistance to thermal cracking and decomposition
  • Minimal interference with heat transfer capability
  • High specific heat and thermal conductivity
  • Rapid heat dissipation
  • Superior low temperature fluidity
  • Excellent thermal and oxidation stability
