Therminol® 66 heat transfer fluid

If you’re considering a Therminol® 66 equivalent, Globaltherm® Syntec is a fully compatible solution. Syntec shares all critical Therminol® 66 properties and can be used for topping up existing Therminol 66 systems without negative impact. This miscibility helps in minimising downtime and maintaining system performance.

Key advantages of Globaltherm® Syntec:

  • Immediate shipping available
  • Outstanding thermal stability
  • High performance in liquid phase heat transfer
  • Cost-effective and efficient for long-term use

Globaltherm® Syntec is one of the most popular alternatives on the market today for applications requiring thermal fluids at high temperatures. It operates efficiently at temperatures up to 345°C (653°F) and can be pumped down to -3°C (27°F).

Therminol® 66 MSDS (Material Safety Data Sheet)

Understanding the Therminol® 66 MSDS is crucial for safe handling, storage, and maintenance. The MSDS provides detailed information on the fluid’s physical properties, safety precautions, health hazards, and emergency procedures. Following MSDS guidelines ensures safer operations, particularly when dealing with high temperature processes.

Therminol® 66 is a clear, pale yellow heat transfer fluid made from modified terphenyls, offering reliable liquid phase heat transfer and excellent protection against thermal degradation and system fouling.

Therminol® 66 properties

Therminol® 66 stands out due to its exceptional thermal stability, making it ideal for high temperature operations. Here are its key specifications:

  • Operating temperature range: -3°C to 345°C (27°F to 650°F)
  • Physical state: Clear, pale-yellow liquid
  • Thermal stability: Excellent at sustained high temperatures
  • Pumpability: Maintains flow down to -3°C without difficulty
  • Resistance: Minimises solids formation and fouling, prolonging fluid life and reducing maintenance costs

These features ensure that Therminol® 66 can handle rigorous processing conditions while maintaining system integrity and maximising efficiency.
