A refrigerated air dryer typically achieves a pressure dew point of around 38F（3℃) to 50 F (10℃ ). This is because they cool the air to condense and remove water vapor, and freezing the moisture within the dryer must be avoided, which limits how low they can go. This dew point is sufficient for most general industrial applications.
Minimum dew point: The lowest dew point is usually around 38F（3℃) , which is considered the standard for many applications and corresponds to ISO Class 4.
Maximum dew point: The highest practical dew point is around 50 F (10℃ ) to prevent condensation in the downstream piping
Why it's a limit: The cooling process in a refrigerated dryer relies on the refrigerant cycle. To prevent the condensed water from freezing inside the dryer, which would cause damage, the air is not cooled below the 38F（3℃) mark
