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.

“This successful collaboration of our teams working together developed a fluid that can meet the demands of the newer higher performance systems in the market,” said Steve Elkin, CEO and founder of SolarUS. “These higher performance fluids are a critical component of solar thermal systems as higher temperatures and more demands are being placed on solar thermal production in applications like manufacturing, heating and air conditioning.”

“DuPont Tate & Lyle is pleased to offer SolarUS a renewably sourced glycol for use in So-Blu,” said Lirys Crawford, market development manager for DuPont Tate & Lyle Bio Products. “The qualities of Susterra®1,3-PDO glycol paired with the expertise of SolarUS have enabled the development of an innovative new fluid that will increase the efficiency and lifespan of solar thermal systems.”

Susterra® 1,3-PDO glycol is certified 100 percent biobased by the U.S. Department of Agriculture, making So-Blu an attractive fluid for solar thermal owners seeking renewable content in their products.
