Outdoor Water Solution Freeze Control Unit

Freeze Control Unit for Windmill Aerators Keep your windmill aerator running all winter long with the Freeze Control Unit—a smart solution designed to prevent frozen airlines during cold weather. This self-regulating system detects pressure changes in the airline and automatically injects non-toxic isopropyl alcohol if it senses a blockage caused by freezing condensation. By doing so, it ensures continuous airflow and reliable aeration even in frigid temperatures. Why Winter Aeration Matters If it’s cold enough to freeze your airline, it’s cold enough to freeze your pond. Maintaining proper aeration during the winter is critical for fish health, water quality, and overall ecosystem balance. A bottom-diffused aeration system helps keep a section of the ice open, allowing for gas exchange and reducing the risk of winter fish kills caused by oxygen depletion. Without an open area for oxygen transfer, toxic gases from decomposing organic matter can build up beneath the ice—leading to foul
