Critical moisture measurements

Published:  17 May, 2019

Compressed air supplies are a necessity for industrial applications around the globe. In Europe alone, it is estimated 10% of all industrial electricity consumed is used to produce compressed air. Compressed air can also be used as a safe alternative power source in hazardous locations where there is a risk of fire or explosion, such as mines and oil rigs.

When warm compressed air leaves the compressor, it contains a high level of water vapour, and drying is a necessary part of the process. Any water vapour in the system will condense on cold surfaces and create the risk of corrosion or blockages.

Drying is a crucial part of the compressed air system and there are three options to choose from:

• After coolers (usually combined with another form of dryer)

• Refrigerant dryers

• Desiccant dryers

Dew-point measurements increase the efficiency and economy of drying – read the full article here to find out how dew-point dependent switching (DDS) saves money and ensures the quality of compressed air supplies.
