Final answer:
False, air tanks with alcoholic solution need daily draining to prevent freezing.
Step-by-step explanation:
Air tanks with alcohol added to them to prevent freezing may have reduced moisture, but they still require regular draining. Moisture can accumulate in air tanks as the compressed air cools and condenses the water vapor present in the air.
While alcohol can help to lower the freezing point of water, preventing ice from obstructing the air system during cold weather, it does not entirely remove the water.
Regularly draining air tanks ensures that moisture does not build up and cause operational problems or corrosion over time.
It is important for maintenance and safe operation to stick to a schedule of daily draining, regardless of the presence of alcohol.
