Susterra® Propanediol in Low-Temperature Heat-Transfer Fluids for Process Cooling


The natural choice in glycols.

Susterra® propanediol offers a higher-performing alternative to propylene glycol for use as the primary ingredient in heat-transfer fluid for companies that require non-toxic, food-safe properties.

The low-viscosity profile of Susterra® propanediol reduces pump power consumption and enhances flow rates and pumping efficiencies, which can reduce energy demands and maintenance costs. Plus, every drop of our pure, bio-based glycol is renewably sourced from plant materials, not petroleum.

Now there is choice.
