View glycol concentration chart or use our calculator to determine freezing point and burst point of propylene glycol and ethylene glycol. Identify glycol to water ratio.

Freezing points of propylene glycol based heat-transfer fluids suitable for the food processing industry. For many heat-transfer applications it is necessary to use a heat-transfer fluid with lower freezing point than water.

1) Specific gravity based on propylene glycol solutions with temperature 60oF.

Freezing Points of Aqueous Solutions of Propylene Glycol. Propylene Glycol Freeze Point.

Before using a product sold by a company of the LyondellBasell family of companies, users should make their own independent determination that the product is suitable for the intended use and can be used safely and legally.

freezepoint temperature should be 25°F below the lowest required setpoint (see chart). Water will evaporate from the mixture, and if you continue to add a premixed solution, eventually you will have too much glycol. It is necessary to add water or glycol to maintain proper freezepoint temperature. The

Freezing point according to ASTM D 1177 is the temperature for the first ice crystal formation. DIN 51583 normative establishes the temperature from the product does not flow and there is danger for the circuit integrity.

recommends a glycol solution that can maintain a freezing point of at least 10°F below the lowest anticipated temperature. See Table 2 for Dynalene propylene glycol freezing points for various concentrations.
