IceClear AF
Non-Glycol Anti-Freeze / Heat Transfer Fluid
IceClear® AF is a patented non-toxic, non-glycol, biobased anti-freeze / heat transfer fluid / secondary refridgerant with a food grade multi-metal corrosion inhbitor. Made with highly refined materials, AF is NSF registered with an HT1 rating, allowing use where incidental food contact is possible. AF is specifically formulated as an alternative to petroleum derived 50% propylene glycol (PG) based anti-freeze and heat transfer fluids for industrial applications, especially those with environmental concerns:
- RV Toilet & Water System Winterizer
- Fountain/Water Line Winterizer
- Solar Systems
- Floor Heating Systems
- Directional Drilling Fluid
- Pressure Testing
- Ballast Fluids
- Chiller Fluids

For Heavy Duty and Engine Related Applications, Use IceClear HD.
Derived from agricultural materials or bio-based processes, this environmentally friendly product is engineered to match the freezing point performance of conventional antifreeze products based on glycols (see Figure 1 on right), but with the following advantages:
OUTSTANDING BENEFITS AND FEATURES:
NSF Registered
This product is acceptable for use as a heat transfer fluid where there is possibility of incidental food contact (HT1).
Won’t Dry Out
Due to its viscous nature and hygroscopic character, IceClear® AF will not dry out after initial application, making it effective for extended periods of time as an antifreeze and a dust suppressant.
Environmentally Friendly
IceClear® AF is non-toxic, contains no salts, heavy metals or solvents, it is non-corrosive, fully biodegradable (with a lower BOD/COD than glycol), and it will not affect combustion processes. As part of the government's Federal Biobased Product Procurement Program (FB4P), AF is a BioPreferred Product with a 100% biobased content as tested by ASTM D6866. IceClear® AF is composed of natural ingredients based on abundant and renewable agricultural feedstock materials that are cost effective and readily available.
IceClear® AF has been tested to OECD 310 with results showing it is "readily biodegradable" meaning that there is unequivocal evidence that IceClear® AF is rapidly mineralized to inorganic components and biomass. IceClear® AF also meets the definitions of "inherently biodegradable" and "ultimately biodegradable" meaning that there is a reasonable expectation that they will eventually be completely mineralized in aerobic environments.
Cost-effective
IceClear® AF is formulated from complex carbohydrates derived from renewable resources and/or process side streams that facilitate cost-effective and not subject to the market swings of glycols.
Testing/Physical Properties
IceClear® AF is a glycerin based product, DO NOT use testers designed for glycols. Freeze point range can quickly be determined by a special tester (pictured left) available from Orison or more accurately by a refractometer (Brix). The tester is included free with all orders of 4 gallons or more.
IceClear® AF is slightly more viscous than conventional antifreeze materials. As such, it adheres to particle surfaces and clings to transportation and conveying equipment with little run-off and settling. This prevents freezing, clumping and sticking, and keeps product moving freely.
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.
IceClear AF is also supplied without the corrosion inhibitor package under the name IceClear PGX.
For Heavy Duty Automotive and Engine Related Applications, Use IceClear HD.
