Cooltrans Plus SP

High-temperature heat transfer fluid

Cooltrans Plus SP is a concentrated, non-toxic, high-temperature heat transfer fluid and antifreeze based on mono propylene glycol (MPG). It has been formulated with vaporisable inhibitors specifically designed for use in multiple high temperature applications, such as solar thermal systems, ensuring reliable performance under demanding conditions.

The advanced inhibitor package in Cooltrans Plus SP provides exceptional protection for a wide range of metals and has been tested according to the internationally recognised ASTM D1384-05 corrosion testing standard. This ensures both long-term system reliability and protection against corrosion-related damage.

In addition to its high thermal performance, Cooltrans Plus SP is readily biodegradable, meaning it will not persist in the environment or accumulate, making it a safer and more sustainable choice for solar thermal applications. The fluid is engineered to operate effectively across a broad temperature range from -45°C to 200°C, making it ideal for high-temperature systems.

Key features of Cooltrans Plus SP:

  • Designed for use in solar thermal systems
  • Contains vaporisable corrosion inhibitors for added protection at high temperatures
  • Buffered to resist degradation and acidification
  • Non-toxic
  • Temperature range -45°C to 200°C
