The freeze control option is
the windmill is located
away from the pondís edge.
Anytime air is compressed,
condensation is created and
can accumulate in the pipeline.
During freezing weather
this condensation can
freeze and stop the
windmill from working.
The freeze control option constantly checks line pressure. If
the line starts to freeze, the control valve opens and feeds
Ethanol alcohol (or Rubbing alcohol) into the line which melts
the ice. Then the valve closes and normal operation resumes.
