What is the purpose of an alcohol evaporator in air brake systems?

Explanation:
In cold weather, moisture in the compressed air can freeze inside brake valves and lines, causing braking problems. An alcohol evaporator adds a small amount of alcohol into the air stream, which lowers the freezing point of that moisture. The alcohol is drawn from a reservoir and vaporizes as the air passes through the evaporator, then mixes with the compressed air. This anti-freeze effect helps prevent ice from forming in the valves, keeping the air brake system functioning reliably in freezing conditions. It isn’t about increasing pressure, fuel efficiency, or reducing wear.
