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.


Glycol Addition Calculator; Use this calculator when you need to determine how much more glycol is required to lower the freeze point to already filled chilled water loop. Note this calculation takes into account that some of the glycol in the circuit must be removed to add higher percent glycol to lower the freeze point.


of 95.5 percent propylene glycol, dipotassium phosphate and water. The fluid is colorless (water white). DOWFROST fluid has an operating temperature range of -50°F to 250°F (-46°C to 121°C) and solutions in water provide freeze protection to below -60°F (-51°C) and burst


Technical Data Sheet DOW FROSTTM Product Type Inhibited Propylene Glycol-based heat transfer fluid Applications Recommended -45°C (-50°F) to 120°C (250°F) Use Temperature Range Description DOWFROST heat transfer fluid contains specially formulated packages of industrial inhibitors that help prevent corrosion. Because propylene glycol fluids have low acute oral


CHOOSING THE PROPER GLYCOL: For getting the most efficiency from your system, a propylene glycol such as “DowFrost” is a must. DowFrost contains special corrosion inhibitors for low system maintenance and better transfer capabilities than normal glycols. It also has a much longer fluid life up, to 20 years in some cases. USE OF PLAIN GLYCOL:


Glycol Charts & About Glycol. ABOUT GLYCOL IN CHILLERS. A chiller will run without glycol as long as the fluid temperature in the system is above freezing. Glycol or other inhibitors are recommended for most process cooling applications even if the fluid temperature doesn’t reach temperatures near freezing. ... A 40% solution of propylene ...


Dynalene Propylene Glycol is an inhibited non-toxic propylene glycol heat transfer fluid which offers users a stable, safe, and efficient product for applications where freeze protection is needed.
