dew point

The temperature at which air becomes saturated with water vapor and dew forms. The dew point varies depending on how much water vapor is in the air.

This threshold corresponds to a wet-bulb temperature of about 35[degrees]C (95[degrees]F)--conditions associated with, for example, a dry-bulb temperature of 40[degrees]C (104[degrees]F) and a dewpoint temperature near 33.5[degrees]C (92.3[degrees]F).
EXCEPTIONAL HEAT-HUMIDITY COMBINATIONS INCREASING FASTER THAN EXPECTED
The principle of operation of a hot-air dryer is simple: Hot air will absorb and hold more water than cool air; for example, ambient air at 75 F with a dewpoint temperature of 60 F has a relative humidity of 59.62%, meaning it has absorbed over half of the water that it can absorb at that temperature.
Why Drying Polyolefins Might Be Right for Your Process
The dewpoint of a refrigeration dryer is dictated by its ability to cool the air to the desired dewpoint temperature and then the efficiency of the liquid removal separator.
Dryer types--where to start with selection: Whether designing new systems, or reviewing existing systems, the first step should be to define exactly what are the compressed air purity requirements. Ensuring you have the correct advice is key and the dryer is only part of the process. The British Compressed Air Society (BCAS) reports
It forms when humid air cools sufficiently for water vapor to saturate and produce condensation--the dewpoint temperature. On a dry summer day in California, this temperature might be 20 degrees F, and the weather remains clear.

That equates to a dewpoint temperature of about 55 degrees F.

This can be implemented by maintaining the temperature of the controlled space air at a constant value above the outdoor air's morning minimum temperature (Method 1), maintaining the temperature of the controlled space air at a constant value above the air's dewpoint temperature (Method 2), or adjusting the temperature of the controlled space air according to a preset RH (Method 3).

The bags absorb 280 percent of their weight in moisture at 90 percent relative humidity at 77 degrees F, keeping the dewpoint temperature below the actual temperature, even with day-night fluctuations.

For 1 May-30 September, for each year from 1980 to 1996, Environment Canada provided hourly values of air temperature and dewpoint temperature from the weather station at the Toronto Pearson International Airport in Etobicoke, which is located approximately 15 km from downtown Toronto.
