Windmill aerators can save $30 to $50 per month in electrical costs, paying for themselves in a few short years.

Becker Windmill™ Freeze Control

Windmill Freeze Control Units help keep air lines from the windmill to the pond from freezing. These units are recommended whenever the windmill is located away from the pond’s edge. If the line starts to freeze, the control valve opens and feeds ethanol alcohol (or rubbing alcohol) into the line to melt the ice, the valve then closes and normal operation resumes.
