I used it straight out of the container. Directions were on the container
I would say it is OK to use for that application. I use it in my Solar Hot Water Panels.
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.
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.
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.
No. You need to use the Cryo-Tek A/L (#35283) for aluminum or Cryo-Tek Universal (#35331).
Check with your local store as to availability.
I do not believe it will
