Propylene Glycol and water will evaporate off an open boiler system. They evaporate at a rate proportionate to what is in the tank. So from a concentration perspective, the solution left in the tank shouldn’t change dramatically (maybe 1 or 2 percent higher) based on evaporation.

No. Cryo-Tek is propylene glycol and not designed or tested to be used in automobiles. Please check with the auto manufacturer as to what they recommend.

How many gallons to protect to at least -10F in 1200 feet of 7/8 Pex Tubing?

Answers

This works out to approx. 45 gallons total. To get a -10 degree freeze protection you would need 40 gallons of Cryo-Tek Original and 5 gallons of water.

Is 15 gal of regular Cryo-tek too corrosive for an 18 gal system? Since I’m due for my 5-year antifreeze change now ..

Answer

Cryo-tek comes already diluted at different ratios out of the container depending on which one you choose. Please check with Oatey to confirm once you determine your desired freeze protection and we can then provide you our suggested product. In regards to corrosion, you need to confirm with your Boiler manufacturer as to what level of propylene glycol they want you to not exceed. You would only want to add Sludgehammer if your pH is below 9.5 for non-aluminum system. You would add one container and let it circulate and take another pH reading.

The only problem I had was while I was at the store none of the 5 employees I spoke with were able to find the product. I had to return to the store after I was notified an hour after I left that the product was found. Cost me time and money

Cryo- tek part no. 35253
I bought 4 of these going by the picture showing Cryo-tek AG which is 95% antifreeze. what I got was part no. 35253 which is premixed 45%antifreeze as does the description. The picture shows Cryo-tek AG and the correct part no.35282. When I check my account and purchases, it lists that I bought Cryo-tek AG oatey part no. 35253 and a picture of Cryo-tek AG. so check the bottle, home depot pictures and part numbers are mixed up. if you want actual concentrated 95% polypropylene gycol get the bottle that says AG otherwise you will get pre-mixed product and not as strong.

It does what it supposed to do: it lowers the freezing point of coolant and prevents corrosion. Because it's based upon propylene glycol, it has the added benefits of being non-toxic and provides lubrication for pumps.
