CORROSIVITY OF GLYCOL ANTIFREEZES IN SOLAR SYSTEMS.

Author(s) : FORESTI R. J.

Summary

ANTIFREEZE SOLUTIONS FROM THE SOLAR COLLECTOR LOOPS WERE CHEMICALLY ANALYZED TO DETERMINE THE NATURE OF THE ANTIFREEZES AND THEIR EFFECT ON CORROSION. A WIDE VARIETY OF ANTIFREEZE-CORROSION INHIBITOR SYSTEMS WERE BEING USED, AND NO PATTERN COULD BE DETECTED TO INDICATE A PREFERENCE OF QUALITY. A QUESTION WAS RAISED ON TOXICITY, WHERE TOXIC INHIBITORS WERE ADDED TO NONTOXIC ANTIFREEZES, IE, PROPYLENE GLYCOL. IT APPEARS THE CORROSION IS NOT A SERIOUS PROBLEM FOR INHIBITED ETHYLENE OR PROPYLENE GLYCOL SOLUTIONS IN PROPERLY CONSTRUCTED COPPER SYSTEMS.
