550 Gallons – BoilerGlycol™ DF1 – 100% USP Grade Inhibited Propylene Glycol



  • Product Code: DF1-100%
  • Highest USP-certified base propylene glycol purity (assay) available in the industry at Greater than 99.8% Guaranteed.
  • Designed specifically for use in boiler systems.
    • Made for use in any industrial, commercial, or food industry boiler application.
  • Base propylene glycol and inhibitor package are both Generally Recognized As Safe (GRAS) by the United States Food & Drug Administration as food additives under Parts 182 and 184 of the Food Additive Regulations.
  • Proprietary anti-corrosion package maintains stable pH in system piping thus drastically inhibiting the degradation of metallic piping materials and system components.
  • Provides superior freeze protection in any boiler water/glycol system.
  • Dramatically reduces risk of piping or component bursting in presence of low ambient temperature.
  • Low vapor pressure allows drastic reduction in glycol loss due to atmospheric evaporation.
  • Wide functional temperature range allows for use in many situations (-50F to 250F).
  • Enhances lubrication and fluidity in boiler water loop system.
  • Safe to handle, store, and ship. Product is non-toxic and non-corrosive.
  • Product not considered hazardous by OSHA/HAZMAT standards.
  • Standard color of fluid product is clear (colorless), however product can be purchased with a light blue tint for simplified leak detection for small upgrade cost.
  • Longest shelf life in the industry at 24 months, when stored in 104F (40C) in closed containers and free from UV light.
  • Manufactured through award-winning sustainable hydrogen peroxide to propylene oxide (HPPO) technology.
    • Reduces wastewater by approximately 70-80% and energy used by 35% when compared with conventional propylene oxide manufacturing technology.
