Winter shouldn't put your pond-or your fish-at risk. The Freeze Control Unit is designed to ensure your windmill aeration system keeps running, even in the harshest conditions. Frozen airlines are a common winter problem that can shut down aeration, leading to oxygen depletion, toxic gas buildup, and fish kills. This unit eliminates that risk by automatically releasing a small, measured dose of eco-safe isopropyl alcohol whenever line pressure builds from ice blockage. That means no rushing outside in freezing temperatures to thaw your system and no lost aeration when your pond needs it most. With the Freeze Control Unit, your aeration stays consistent, your ecosystem remains balanced, and your fish survive the winter-giving you total peace of mind. Engineered for seamless integration into Outdoor Water Solutions windmills, itÕs a set-and-forget safeguard trusted by pond owners, fisheries, and land managers across cold climates. If protecting your investment and your pondÕs health matters, this is the fail-safe solution youÕve been waiting for.
