A good method of removing moisture from air before it goes into the air receiver is to:

Removing moisture from air before it enters the air receiver is essential for preventing corrosion and ensuring the efficiency of air-operated systems. Cooling the air is an effective method for moisture removal because as the temperature of air decreases, its capacity to hold moisture also decreases. This process leads to condensation, where water vapor in the air turns into liquid, allowing it to be separated effectively.

In practical applications, cooling may involve the use of refrigerant coils or air-to-air heat exchangers, making it a common step in industrial processes. This method is commonly found in systems like compressed air dryers, where cooling is used to reduce humidity levels before the air is stored or used.

While other methods like heating can increase the air's capacity to hold moisture, making it less effective in reducing humidity, pressurizing the air does not remove moisture directly but rather compresses it. Increasing the velocity of air might help in reducing moisture in certain contexts but does not facilitate effective condensation or removal like cooling does. Thus, cooling is the most effective approach to achieving the desired reduction in moisture content before air storage.
