Asked by STS November 19, 2019I would say it is OK to use for that application. I use it in my Solar Hot Water Panels.
When the water evaporates from my Classic wood burning furnace, does the Cyro-Tek become more co...
Asked by Joanne September 16, 2019Propylene 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.
can I use this in my car
Asked by smiley March 18, 2019No. 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?
Asked by Kevin August 10, 2018This 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 ..
Asked by AR July 11, 2018Cryo-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.
Can I use this product with an aluminum heat exchanger?
Asked by John January 12, 2018No. You need to use the Cryo-Tek A/L (#35283) for aluminum or Cryo-Tek Universal (#35331).
