Windmill Freeze Control Unit | Winter Protection for Pond

Aeration Systems

Protect your pond aeration system all winter long with the Outdoor Water Solutions Freeze Control Unit. Designed specifically for windmill-powered aeration systems, this automatic freeze protection device helps prevent frozen airlines that can interrupt airflow, reduce oxygen levels, and threaten the health of your pond during cold weather.

When ice begins to block the airline, pressure naturally builds within the system. The Freeze Control Unit automatically releases a controlled amount of eco-safe isopropyl alcohol into the airline, helping clear ice buildup and restore consistent airflow without manual intervention. This automatic operation minimizes downtime and helps keep your aeration system working when your pond needs it most.

By maintaining continuous airflow throughout the winter, the Freeze Control Unit helps preserve dissolved oxygen levels, reduce harmful gas buildup beneath the ice, and support healthier fish and aquatic life. It also helps protect your windmill compressor from unnecessary strain caused by blocked airlines, extending the life of your aeration equipment.

Designed for seamless integration with Outdoor Water Solutions windmill aeration systems, this low-maintenance accessory provides dependable winter protection for ponds, fisheries, farms, and rural properties in cold-weather climates.
