Therminol ADX-10 Heat Transfer Fluid


Therminol ADX10 is a low viscosity, synthetic organic heat transfer fluid particularly recommended for indirect liquid phase process heating at medium temperatures.

Performance Benefits.

  • Easy Operation—Easy start-up and shutdown at low temperatures due to excellent low temperature pumpability down to temperatures of -50C.
  • Excellent Low Temperature Properties—Low pour point (-80°C) and excellent low-temperature viscosity, get rid of the need for steam or other forms of heat tracing.
