Oct. 31, 2014: SolarUS, DuPont Tate & Lyle Develop New Solar Thermal Heat Transfer Fluid
Product Provides Longer Life and Higher Efficiency
WILMINGTON, Del. — DuPont Tate & Lyle Bio Products has collaborated with SolarUS to launch a new biobased heat transfer fluid that will utilize Susterra® 1,3-propanediol (PDO), a high-performance glycol alternative. The new fluid, So-Blu, will offer solar thermal system owners freeze, corrosion, and extreme heat protection resulting in increased system and equipment efficiency and lifespan, said the companies.
According to DuPont Tate & Lyle and SolarUS, current solar thermal fluids are prone to a number of issues such as degradation that results in the formation of viscous deposits in the solar equipment, leading to a decrease in efficiency. However, So-Blu will offer higher thermal stability and protection against corrosion deposits, giving systems a longer life and higher efficiency throughout the life of the system.
