AIR DRYERS

The moisture content determines the quality. What for is torture people, machine and production lines is a necessity: the air extremely dry. Because only then is it possible to avoid corrosion problems.

EI decisive factor is the relative humidity, which in the art, particularly for compressed air, can be described by the dew point under pressure. Corrosion in piping systems as well as water vapor too machines may cause shutdowns. The blame for this is usually very humid compressed air, however, can be avoided by using appropriate dryers.

If the intention is to avoid damages that result stops, it is essential to reduce the high content of water vapor. But how should really be dry compressed air?. The main measure is the relative humidity. Below 50% no need to fear the occurrence of corrosion in pipes and containers.

Another problem may also come from outside freezing pipes exposed to the elements. In winter, the compressed air can be cooled to cause condensation of water, which then freezes.

When the relative humidity exceeds 50% limit, the compressed air must be treated properly. The relative humidity indicates the water content in the air with respect to the saturation value. With increasing temperature, the air can absorb more water vapor to reach the saturation point, called the dew point. If you increase the amount of water vapor could not absorb air and then condense. Conversely, even when the warm air is cooled, it can be up to the dew point, as the amount of water vapor that can be absorbed decreases with temperature. Normally, for a given pressure, the dew point is indicated by a temperature, which means that the dew point is expressed as the temperature at which this occurs.

► Refrigeration Dryers. To +3 ° C dew point. FX and FD series.

► Adsorption dryers. -20, -40, -70 ° C dewpoint.

► Membrane dryers. Reduced from 32 to 50 ° C dew point.
