Never use less than 20% glycol in the mix. Never use more than 60% glycol in the mix. Always mix in as little glycol as possible to keep optimum efficiency, but never risk burst pipes. Always pick a glycol that provides protection at 10°F lower (around 6°C) than the lowest temperature ever …

Aug 24, 2016· Many glycol vendors will provide glycol that is already pre-mixed. This is the best way to add glycol as it guarantees the correct glycol concentration, and that the water used in the mixture is free of contaminants. If 100 per cent glycol is purchased then on-site mixing is required, and this can cause issues if not done properly. When mixing glycol on-site with water it is highly recommended …
For many heat-transfer applications it is necessary to use a heat-transfer fluid with lower freezing point than water. The most common antifreeze fluid - ethylene glycol - must not be used where there is a chance of leakage to potable water or food processing systems. In food processing systems the common heat-transfer fluid is based on propylene glycol.
Oct 30, 2014· Common Foods and Drinks Hiding the Antifreeze Compound. Propylene glycol is considered safe by the FDA in small quantities, although it can be toxic in large doses. And it's more common than you think. It's widely used in food and drink products as a thickener and preservative, or to add a little bit of sweetness.

Aug 04, 2013· Best Answer: About 41% by weight of propylene glycol in water will get you to a freezing point of - 10° F. Since propylene glycol has a density of 1.04 g/cm^3, this corresponds to 42.5% by volume. The easiest thing to do if your system is half full is just to fill it the rest of the way with propylene glycol.
To make a small amount of the mixture, you will need a 1 cc syringe that measures accurately to the tenth of a cc. Draw up 0.1 cc of Ivermectin solution in a 1 cc syringe, and mix well with 3 cc of glycerin, propylene glycol, or vegetable oil, giving you 3 ccs at a dilution ratio of 30:1.
