PERFORMANCE

BioFROST® meets the requirements of ASTM D8039* Heat Transfer Fluid for HVAC, and ASTM D1384, a corrosion standard commonly used to determine the ability of the fluid to provide corrosion inhibition in heated applications. Our quality corrosion package, provides outstanding corrosion protection of steel, copper, brass, solder, cast aluminum, and cast iron. BioFROST® lubricates pumps and valves, provides scaling resistance, is fully compatible with gaskets, seals, elastomers and other non-metallic pump and system parts. BioFROST® is a drop-in replacement for other PG fluids and is engineered to equal the heat transfer, antifreeze, and corrosion inhibition performance characteristics.

SAFETY/ENVIRONMENT

BioFROST® is a 100% certified USDA Biobased Product as tested by ASTM D6866 through the USDA BioPreferred® Program and is NSF HT1 registered for incidental food contact. BioFROST® is not a petroleum derived product, it utilizes USP Grade 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 among the safest and most environmentally friendly products.

  • NSF registered HT1 (incidental food contact)
  • 100% Biobased USDA BioPreferred®
  • Readily Biodegradable
  • Non-Toxic
  • Designed for Environmentally Sensitive Applications

 

NSF REGISTERED

This product is acceptable for use as a heat transfer fluid where there is possibility of incidental food contact (HT1).

 

TESTING

BioFROST® 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.

 

*Addition of TRAMFLOC® 1142 FOAM CONTROL AGENT required for ASTM D8309. TRAMFLOC® 1142 FOAM CONTROL AGENT is a nonionic, nonsilicone, food grade defoamer. TRAMFLOC® 1142 FOAM CONTROL AGENT performs well in a wide range of pH and temperatures. All ingredients used in the manufacture of TRAMFLOC® 1142 FOAM CONTROL AGENT are either GRAS or listed in the Code of Federal Regulations: Title 21, Section 173.340. Recommended use at 1 oz/ 10 - 20 gallons of system fluid.

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