ANTIfreeze selection & use (continued)

Propylene Glycol – Non-toxic, non-corrosive, expensive, hard to handle when cold, poorest heat transfer, has formed “slime-type” coatings inside system piping. Propylene Glycol is acceptable in systems anticipating loop temperatures no colder than 40°F (4.4°C). These systems typically use antifreeze because of low ambient conditions (outside plumbing or cooling tower, etc.). When loop temperatures are below 40°F, the fluid becomes very difficult to pump and heat transfer characteristics suffer greatly. Only food grade propylene glycol is recommended to prevent the corrosion inhibitors from reacting with local water causing “slime-type” coatings inside heat exchangers. If propylene glycol must be used (code requirements), careful consideration of loop Reynolds numbers, pump selection and pressure drop must be considered.

Potassium Acetate (GS4) – Non-toxic, good heat transfer, high price, non-corrosive with added inhibitors, low viscosity. Due to its low surface tension, Potassium Acetate has been known to leak through mechanical fittings and certain thread sealants. A variant of the salt family, it can be extremely corrosive when exposed to air. Potassium Acetate is not recommended in ground loop applications due to the leaking and (ultimately) corrosion problems associated with it.

Note: Consult with your local distributor if you have questions regarding antifreeze selection and any comments to report about problems or success with any particular methods in your area.
