The industry is increasing in scope due to the wide range of innovative solutions being used to reduce the reliance on fossil fuels for electricity, heat and petrochemical based fuels.

Renewable technologies are typically associated with natural energy to generate electricity with fuel sources including wind, solar, marine, hydro and solar.

However, this is now combined with sustainable sources such as biomass, biogas and biofuel to deliver a mix of technologies necessary for the continuing growth of this sector.

Therminol ® heat transfer fluids have recognised experience in this industry that started in the 1980’s with concentrated solar power plants, this has now progressed to many new areas where reliable, efficient heat transfer is required.

For medium temperature, low pressure applications

Operational temperature range: -25o to 290oC (-15o to 550oF)

Synthetic fluid that can resist the effects of oxidation 10 times more effectively than mineral oils

Cost effective product offering long term performance

System start up is quick and easy due to low temperature pumpability at -25oC, well beyond the capabilities of mineral oils.



For high temperature, low pressure applications

Operational temperature range -20o to 315oC (-4o to 600oF)

Meets the U.S. Food & Drug Administration requirements defined in 21 CFR 172.878 for low toxicity and purity.

Operates at maximum bulk temperature without the need of stabilizing additives reducing associated risks of system fouling.



For high temperature, low pressure applications

Operational temperature range: -49o to 315oC (-56o to 600oF)

Cost effective fluid for high temperature processes, offering long term performance.

Provides reliable, trouble-free operation reducing maintenance costs.



For high temperature, low pressure applications

Operational temperature range: -3o to 345oC (27o to 650oF)

High performance synthetic heat transfer fluid offering extended life and very low top-up rates

Specifically engineered to resist solids formation and system fouling, providing more reliable operation and fewer fluid change outs.

Therminol 66 has made its reputation for its outstanding thermal stability in operation.



For ultra-high temperature, medium pressure applications

Operational temperature range: -10o to 380oC (15o to 715oF)

Specialist properties minimise the formation of low boilers and eliminate the risk of insoluble high boilers and fouling.

Low temperature fluidity properties reduce capital costs related to freeze protection

A high temperature liquid phase heat transfer fluid with excellent thermal stability.



For ultra-high temperature, liquid or vapour phase operations

Operational temperature range: 12o to 400oC (54o to 750oF)

It can be used as a liquid heat transfer fluid or as a boiling-condensing heat transfer medium.

Combines exceptional heat stability and low viscosity across a wide operating range.
