DuPont Joint Venture Develops New Fluid For Solar Thermal


DuPont Tate & Lyle BioProducts, a joint venture between DuPont and renewable ingredients manufacturer Tate & Lyle, has developed Greenway, a solar heat transfer fluid manufactured by Climalife and made with Susterra propanediol.

Susterra propanediol offers solar thermal equipment owners a high-performing, bio-based glycol that can improve energy efficiency and reduce maintenance costs, the company says.

‘The Greenway bio-based heat transfer fluids offer unique technical properties such as excellent thermal stability at high temperature for thermal solar applications and low viscosity at low temperature for cooling applications,’ explains Doug Hopek, market development manager for DuPont Tate & Lyle BioProducts.
