Inhibited Propylene Glycol / Food Chill Propylene Glycol
Food Grade / Environmentally Friendly Antifreeze
by Duda Energy
Propylene glycol is a viscous, oily fluid which is commonly used in many products. Propylene glycol is a non-toxic antifreeze which is safe for the environment. Should a leak occur in a solar water heating system it will not cause problems in contamination to the water supply. If it's used as an antifreeze for a radiator in car, it will not cause harm to the environment.
Like other glycols, Propylene Glycol may begin to break down and become acidic when it reaches temperatures of 250°F or more. As it becomes more acidic, it will attack metals that it comes in contact with. This leads to corrosion of the metals and eventually system failure. As a precaution, in solar water heater systems and other antifreeze systems, propylene glycol with inhibitors is used. These inhibitors coat the metals of the system to help protect them from corrosion. When the propylene glycol becomes too acidic though, it should be changed out with fresh inhibited propylene glycol to help maintain the system. For solar water heater systems, we recommend flushing the system after freezing temperatures are no longer a problem, and using straight water, since stagnation temperatures may be reached in the hotter summer times, which breaks down the propylene glycol.
For antifreeze applications, we recommend using no more than a 60% by weight solution in distilled water. Water has a high specific heat capacity, so only the appropriate percentage should be used to prevent freezing and boiling. Excessive use of propylene glycol will cause the antifreeze to lose its ability to retain sudden increases in heat and often cause system failure, especially in vehicles. (This is the same rule for ethylene glycol as all) Use the following table as a guide for your antifreeze application.You buy 5 Gallons Pail of Inhibited / Food Chill Propylene Glycol Drink-Safe Antifreeze for Solar Water Heater Systems with Coupon : KOPA will be discounted 10%
