Moisture measurements for compressed air dryers
28 May 2019
Dew-point dependent switching (DDS) can save money and ensure the quality of compressed air supplies, explains Michell Instruments.
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
