4.5 Preparation of Glycol SolutionsGlycol Cooled/GLYCOOL ModelsTypical ethylene glycol manufacturers and suppliers are Union Carbide (Ucartherm) or Dow ChemicalCompany (Dowtherm SR-1). These ethylene glycols are supplied with an inhibitor and do not containan anti-leak formula.NOTEFor glycol solution preparation and periodic testing, follow manufacturer'srecommendations. Do not mix products of different manufacturers.!CAUTIONAutomotive antifreeze is unacceptable and must NOT be used.Commercial ethylene glycol, when pure, is generally less corrosive to the common metals of constructionthan water itself. Aqueous solutions of these glycols, however, assume the corrosivity of thewater from which they are prepared and may become increasingly corrosive with use if not properlyinhibited.There are two basic types of corrosion inhibition; they are classified as corrosion inhibitors or environmentalstabilizers. The corrosion inhibitors function by forming a surface barrier that protects themetals from attack. Environmental stabilizers, while not corrosion inhibitors in the strict sense of theword, decrease corrosion by stabilizing or favorably altering the overall environment. An alkalinebuffer, such as borax, is a simple example, since its prime purpose is to maintain an alkaline condition(pH above 7).The quality of the water used for dilution must be considered because water may contain corrosiveelements which reduce the effectiveness of the inhibited formulation. Preferably, surface water that isclassified as soft (low in chloride and sulfate ion content—less than 100 parts per million each) shouldbe used. Before an inhibited glycol solution is charged into a new or old system, residual contaminantssuch as sludge, rust, brine deposits, oil, etc., should be flushed out as completely as possible.Avoid the use of strong acid cleaners. However, if they are required, inhibited acids should be considered.In any event, assure that the cleaning agent is completely removed before charging with glycol.Contact <strong>Liebert</strong> Customer Service and Support for additional recommendations.!CAUTIONGalvanized pipe must not be used in glycol systems.45
