Century Heat Transfer Fluid - Non-Corrosive, Non-Toxic Propylene Glycol RV Antifreeze for Heating Systems | Concentrated (Requires Dilution) | Recommended by Aqua-Hot, Oasis & Timberline - Red, 32oz

I use a water chiller for my OMTech 2080 100w Co2 laser. It's very important that the tube is kept at a steady temperature. This fluid maintains the temperature so much closer than without it - it's amazing stuff. I combine this with a "water wetter" product that also helps.

Great

Comes in concentrate, add your own water.

This is the only source I have found for the concentrated quart sized red boiler fluid. Easy to store quart sized Aquahot approved heat transfer fluid. I have learned the yellow and red colored fluid are only different in color and can be mixed. But why mix when you can buy and use the red in your Aquahot Hydronic system? Ships fast. Mix with distilled water 2 to 1 for 3/4 gallon of fluid.

Great. Product at a fair price and fast delivery

Mix per directions and you should have no issues. 4 stars only because I believe it is over priced.

IT IS NOT 32OZ It mixes one part to three and it's continence is barely 1/3 of a gallon. Buy one bottle for every gallon you need

Pretty cut and dry with what you have to do mixing this up and adding into the Aqua hot as needed
