As the primary ingredient in heat transfer fluids, Susterra® propanediol functions as a higher-performing, food safe glycol for process heating and cooling. Propanediol has unique performance advantages at both high and low temperatures. It can also directly replace propylene glycol.
Based on Susterra® propanediol, Hydratech’s ECO Renewable Glycols utilize the extensive environmental advantages and significant performance gains of Susterra® PDO.
Benefits of propanediol based fluids include:
- Lower viscosity at lower temperatures compared with propylene glycol—for greater process cooling efficiency and reduced energy consumption
- Excellent freeze-point depression for aqueous solution applications
- Demonstrates less thermal degradation than propylene glycol and ethylene glycol in high temperature applications
- Higher boiling point than propylene glycol and ethylene glycol
- USDA BioPreferred® certified as 100% bio-based
- Susterra® propanediol is a 100% bio-based material made from regeneratively farmed U.S. dent corn
- Safe, non-toxic, and readily biodegradable
- Approved for incidental food contact under the NSF International HTX-1 specification
Susterra® PDO based Coolflow ECO heat transfer fluid and antifreeze is effective in many low-temperature applications including:
- Food and beverage process cooling
- Immersion freezing
- Cooling liquid foods and dairy products
- Fermentation and maturation cooling
- Carbonated beverage cooling
- Plastic bottle blow-molding cooling
- Ice systems
- Data center and server room cooling
- Single-fluid process cooling
- Closed-loop, water-based HVAC applications
In high-heat applications such as solar and geothermal process heating, Solaris ECO (Solar) and Thermox® ECO (Heat Pumps), improve thermal stability and last longer than propylene glycol based fluids.
