Questions and Answers for Hercules Cryo-Tek AG Arctic Grade 1 gal. Corrosion-Resistant Antifreeze

A:  Yes you could but this is much to expensive to use for this purpose. I would use RV antifreeze found at your local box stores.

A:  Yes, you can use any of our Cryo-Tek products as a winterizing antifreeze such as the uses you are describing.

A:  Cryo-Tek is designed for use in heating and cooling systems - closed loop. It is not intended for environmental release. Certainly, any flora and fauna in your waterfall will not be favorably affected. Likewise, its color and chemicals may adversely affect the materials of construction of your waterfall. Thus your planned draining and replacement may not completely purge the Cryo-Tek and its residual effects. Lastly, while this antifreeze "sees" the wetted boundaries of circulating pumps, those are HVAC pumps. You will need to assess the chemical compatibility of your pump's seals, impeller, etc. Check your pump's product data sheet and/or contact its manufacturer. (By the way, the flow rate of your pump affects none of this.)

A:  you will need approximately 40 gallons of Cryo-Tek AG and 60 gallons of dionized water.

A:  The antifreeze/water solution is effective to prevent freezing, depending upon the temperature at which you desire protection. See https://www.oatey.com/ASSETS/DOCUMENTS/ITEMS/EN/Cryo-TekAG.pdf.

A:  It depends upon the level of freeze protection one wishes to reach.

A:  One should not use any antifreeze unless there is a chance of freezing. Plain water transmits more heat exchange than it does with any antifreeze materials in it.

A:  No it does not. I have used this for 18 years now.

A:  There is heat transfer with this product depending on the mixing ratios. We follow the Dow Frost charts for propylene glycol that can be found online.
