Typical applications of our dew point probes in the industrial sector
Vaisala DRYCAP dew point probes measure the dew point in industrial environments where the humidity in the gas is usually very low. The dew point is a crucial indicator here: if it is not adequately monitored, this can lead to production downtime, machine damage and reduced product quality. The dew point is measured in a variety of drying and heat treatment processes, for example in plastic drying, in baking ovens or in food drying. Humidity control also plays an important role in compressed air systems, as excessive moisture content can lead to quality defects, icing or corrosion. Other important areas of application include medical gases, dry production environments for lithium batteries and gas-insulated high-voltage systems in energy supply.
