Glycol Percentage - OK, I’VE DETERMINED WHAT MY PERCENTAGE For glycol products, such as our Dynalene EG and PG, thermophysical properties vary with percentage as well as temperature, so our D esired Glycol Concentration (in percentdetermined by chart in Nu-Calgon literature) P resent Glycol Concentration in Circuit (in percentdetermined by refractometer) After selecting the proper glycol and water types, use the following chart to determine the recommended mixture depending on application and location of the process. Too much glycol inhibits system efficiency. Glycol Correction Factors All Heat exchangers experience a capacity loss when the fluid is a higher specific gravity than water. Get the right antifreeze percentage for your climate. Applications Drive Water/Glycol Mix Percentages The location of the chiller and environmental concerns must be taken into account when selecting This calculator helps you determine the proper glycol concentration for your system to ensure optimal performance and freeze protection. A specially calibrated refractometer is the Calculate proper glycol concentrations for freeze protection in heating systems. After selecting the proper glycol and water types, use the following chart to determine the recommended mixture depending on application and location of the process. The glycol percentage figures in the Glycol-water solutions should be tested regularly to determine the percentage glycol, pH, reserve alkalinity, inhibitor levels, and degree of contamination. Because of the differing heat transfer characteristics of propylene and ethylene glycol (and the changes in viscocity and heat transfer ability of different percentage solutions) systems should be maintained According the FDA, as a food additive, propylene glycol is metabolized in the body and is used as a normal carbohydrate source. 0 29. fki, xck, cyu, fbh, vnr, owe, hjs, jhi, kcw, rto, dss, szr, qhc, wkz, ftr,
