• Renewable, plant-based heat transfer fluid formulated with 1,3-propanediol and corrosion inhibitors
  • Water-based, “green liquid” appearance, fully soluble in water
  • Non-flammable with no flash point, and non-toxic with no environmental hazard labeling
  • Biodegradable, meeting OECD criteria with 90–100% degradation within 28 days
  • Ultra-low Global Warming Potential (GWP 1–30)
  • Anti-corrosive H-OAT (Hybrid Organic Acid Technology) formulation, free of nitrites and amines
  • Wide operating range: boiling point of 111°C/232°F and freezing point of -55°C/-67°F
  • Lower viscosity than traditional monopropylene glycol fluids for improved flow efficiency
  • Bacteriostatic properties help prevent microbial growth that can affect system performance
  • Concentrated formula; minimum 40% by volume dilution recommended
  • Suitable for industrial process chillers, direct-to-chip cooling (cold plates/tubes), and specialized manufacturing cooling applications
