Susterra® Propanediol: High Performance Glycol for Solar Thermal Systems

There are many brands of fluids based on propylene glycol. Susterra® propanediol offers solar thermal systems improved performance than other glycols on the market. Switch to a Susterra® propanediol solar thermal fluid and take advantage of the bio based glycol that will decrease fluid degradation and system corrosion and improve the efficiency of your solar thermal installations.

Susterra® propanediol, is used for a range of heat transfer fluids. Susterra® is certified, 100 percent biobased by the U.S. Department of Agriculture, making it attractive for companies seeking to add renewable content to their products.  Susterra® propanediol is a petroleum-free PG and EG alternative.

High Performance Glycol:

  • Higher boiling point vs. PG.
  • Less thermal degradation compared to PG.
  • Delivers excellent freeze point depression for aqueous solution applications.
  • Demonstrates improved viscosity at lower temperatures compared to PG.
  • Contributes to LEED points.

Sustainable Glycol:

  • Susterra® is a 100% USDA bio-based material, renewably and sustainably sourced.
  • Susterra® provides low toxicity, safety, and is readily biodegradable.
  • Petroleum free - PG Alternative
  • Susterra® consumes 40% less energy and reduces greenhouse gas emissions by more than 40% vs. petroleum-based 1,3-propanediol and propylene glycol. LCA
