Save energy and improve compressed air quality
Compressed air is a vital component of many industrial processes. It affects the quality of both the process and the end product. What’s more, compressed air often comprises the largest use of electricity in a plant. Since the importance of clean, dry compressed air – and the cost associated with it – is so high, carefully managing and monitoring of it becomes a crucial task for any plant. One of the most important parameters associated with the quality of compressed air is dew point. Read this blog post for information on dew point. By using stable dew point measurement you can avoid over-drying, save energy and protect the equipment from corrosion.
As energy is a critical and pricy utility, it is wise to optimize all energy-intensive processes. Using pneumatic systems is often significantly more expensive than electricity, especially if energy is wasted. Reliable dew point measurements are the key when it comes to compressed air systems. Besides energy savings, measuring the dew point in the CAS also makes sure that there is no excess humidity that pollutes the compressed air. This is a vital requirement in many industries, such as food & beverage, and pharmaceuticals.

Dew point measurement combined with pressure measurement offers further unique advantages. When dew point data is coupled with live pressure input, conversions to atmospheric pressure or ppm are available online leaving no ambiguity in the information. As an example, regulative requirements of medical gas can be fulfilled easily and quickly. As a market first, Vaisala launched a product specifically designed to meet this need. The Vaisala Dew point and Pressure Transmitter DPT146 is especially well suited for demanding compressed air applications. For more information, view the sampling cell brochure.
Product Manager Joni Partanen from Vaisala shows how easy it is to spot-check an industrial compressed air system. He uses Vaisala Handheld Dewpoint Meter DM70 where he stores several days of data and uploads it to a PC with free MI70 Link Windows software for further analysis. Also the installation of the dew point meter and a sampling system is shown step by step.
The DM70 comes with stable Vaisala DRYCAP sensor technology, but to ensure that it meets regulatory compliance year after year, we recommend Calibration Care agreement for your accredited or standard calibrations. That will help you freeze your calibration costs for up to 4 years. Also several other benefits are included, such as free shipping, planned calibrations, and access to Vaisala MyLearning.
Bottled/compressed air is used as breathing gas in a number of critical applications such as medical & hospital air and self contained breathing apparatus for rescue personnel. Dew point monitoring is required for compliance with most medical gas and breathing air regulations. Stringent control guarantees safe breathing conditions for hospital patients and firefighters.
Vaisala offers various dew point transmitters ideal for monitoring breathing air with dew points down to -80°C and pressures up to 50 bar.
Dryer performance is critical when moisture sensitive materials, such as PET resin and nylon, are dried prior to molding. Dew point measurement can be used to monitor a dryer’s performance or conditions in the hopper, assuring that the drying process remains within specification.
Vaisala has a range of stable and reliable dew point transmitters both for OEM configurations as well as for end users.
For those who prefer a direct measurement of humidity or dew point temperature within the hopper, which can correlate to moisture content of the material in the hopper, Vaisala offers a portable sampling system DSS70A to be used with a hand-held meter DM70.
Handheld Dewpoint Meter DM70 for spot-checking applications and field calibration offers accurate and fast measurement for industrial dew point applications, such as compressed air, metal treatment, additive manufacturing as well as food and plastics drying.
