BioFrost Eco - Biobased Propylene Glycol Antifreeze / Heat Transfer Fluid

BioFROST® Eco is a concentrated, biobased, USP Grade propylene glycol heat transfer fluid formulated to safely provide optimum heat transfer, freeze protection and corrosion protection. Designed to be diluted with DI or RO water 30%-70%, the fluid contains an orange dye for leak detection, however, it can can be provided clear for industrial heat transfer applications. 

Designed for industrial and environmentally sensitive antifreeze, coolant/heat transfer and secondary refridgerant applications, BioFrost® Eco can be used in several industrial heat transfer/antifreeze applications such as:

  • Closed Loop Systems
  • Waste Heat Recovery
  • Chillers
  • Geothermal Systems
  • Hydrostatic/Pressure Testing

For Heavy Duty Automotive, Use IceClear HD.

 

PERFORMANCE

BioFROST® ECO offers an operating range from -50℉ to 250℉ and meets the requirements of ASTM D1384, D2809, and D4340. Our superior NAP FREE (No Nitrites, Amines, or Phosphates) corrosion package, provides outstanding extended corrosion protection of steel, copper, brass, solder, cast aluminum, and cast iron. BioFROST® ECO lubricates pumps and valves, provides scaling resistance, is compatible with gaskets, seals, elastomers and other non-metallic pump and system parts for which propylene glycol is intended. 

 

SAFETY/ENVIRONMENT

BioFROST® ECO is formulated from USP Grade biobased PG. BioFROST® ECO is not a petroleum derived product, it utilizes propylene glycol made from patented renewable processes which converts biobased glycerin into PG. Simply put, if you insist on a PG fluid, the BioFROST® family is the safest and most environmentally friendly products.

  • Biobased
  • Readily Biodegradable
  • Non-Toxic
  • Designed for Environmentally Sensitive Applications

 

Testinghanna refractometer

BioFROST® ECO is a PG based product, DO NOT use testers designed for EG or glycerin. Freeze point range can quickly be determined by a PG refractometer (PG refractometer pictured right).

 

WHAT ABOUT MIXING FLUIDS

Although no negative effects are expected, mixing antifreeze / coolants is not recommended due to varying freeze point depressants and corrosion inhibitor technologies which leads to difficulties determining actual freeze point protection and corrosion inhibition properties. 

The chart below is supplied as a guide for diagnostic / maintenance purposes. The values are calculated values and are only approximations. These are not standards. Custom blends are available.

Note: Diluting this product more than 70% with water may be subject to bacterial contamination.
