## Description

Eliminate your fire hazards and toxic fluids by upgrading your system to BioFROST GEO. GEO is the leader in quality, safety and environmental concerns. GEO is NSF listed (HT1), for use where there is a possibility of incidental food contact. BioFROST GEO is a ready-to-use, biobased, propylene glycol heat transfer fluid formulated to safely provide optimum heat transfer, freeze protection and corrosion protection for geothermal heat pump systems. GEO is a clear 20% PG / inhibitor blend with an optional dye for leak detection. GEO is intended to be used only at full strength. If a lower freeze point is desired, we recommend using BioFROST Concentrate and diluting to desired freeze point. Designed for geothermal and environmentally sensitive antifreeze / coolant / heat transfer applications BioFROST GEO can be used in: Geothermal Systems Non-engine Closed Loop Systems Hydrostatic/Pressure Testing Floor Heating Systems For Engine Related Applications, Use BioFROST Eco, IceClear HD or BioTherm Fluids HD. BioFROST Geo propylene glycol antifreeze / coolant / heat transfer fluidPERFORMANCE BioFROST GEO meets the requirements of 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 long term corrosion protection of steel, copper, brass, solder, cast aluminum, and cast iron. GEO lubricates pumps and valves, provides scaling resistance, is fully compatible with gaskets, seals, elastomers and other non-metallic pump and system parts. Additionally, to make compatibity a non-issue, we have engineered this product to equal the heat transfer, antifreeze, and corrosion inhibition performance characteristics of the most common ready-to-use PG fluid available.
