Pressure dew point is the temperature at which water vapour in compressed air starts to condense at working pressure. It is the key number for choosing a dryer.
Why It Matters
If piping runs through cold areas, the air temperature can drop below the dew point and water will form, causing rust, blocked tools and product defects.
Choosing the Right Value
General plant air often needs a dew point around three degrees Celsius. Cleanrooms, food and outdoor pipelines may need minus forty degrees or lower.
Match Dryer to Dew Point
Refrigerated dryers suit moderate dew points, while desiccant dryers reach the deep dew points required by sensitive processes.
