Certified desiccant air dryer dew point of -90°C.
FAQ: What is dew point?
What is dew point?
The dew point is the temperature at which air becomes saturated with water vapor and can no longer hold all the moisture in the form of vapor, causing it to condense into liquid water. This temperature depends on the pressure and water content of the air. When the air is cooled below the dew point, its moisture capacity is reduced, and airborne water vapor will condense to form liquid water known as dew
The dew point is an important measure in many compressed air applications. It shows the moisture content in the air. A higher dew point means more moisture in the air, which can make it feel more humid and uncomfortable.
TÜV Rheinland Certification
Ensuring quality and compliance in compressed air systems
In the realm of industrial processes, maintaining high standards of quality and compliance is paramount. The TÜV Rheinland certification shows the thorough testing and checks that guarantee the reliability and efficiency of drying systems.
The certificate gives a clear report on the testing and validation of an Atlas Copco BD+ dryer. It shows that the dryer meets international standards.
Overview of the certification
The TÜV Rheinland certification, issued by TÜV Rheinland Energy & Environment GmbH, validates the performance of the Atlas Copco BD+ dryer according to ISO 8573-1: 2010 Part 1, which pertains to contaminants and purity classes. This certification is crucial for industries that need high-quality compressed air. This includes pharmaceuticals, food and beverage, and electronics manufacturing.
Testing and validation process
The certification process involved a series of meticulous tests conducted on the Atlas Copco BD480+ dryer. The tests were designed to measure the humidity in the outlet air stream of the dryer, ensuring that it meets the stringent requirements set by ISO 8573-1: 2010 Part 1 and ISO 8573-3: 2018 Part 2, which outlines the test methods for measuring humidity.
The tests were conducted over a continuous 12-hour period from June 19 to June 20, 2024. The measurements were taken using a dewpoint transmitter, Type Vaisalla DMT152, which has an uncertainty of ± 0.9°C. The pressure at the sampling point was 6.8 bar(e), and the temperature was 32.7°C.
Key Findings: measured dew point -90°C
The key finding from the tests was that the measured pressure dew point was below the criteria of -90°C/-130°F in the compressed air stream. The dew point measurement indicates that the Atlas Copco BD+ dryer effectively removes moisture from the air, ensuring that the compressed air meets the highest standards of purity.
Certification and compliance
TÜV Rheinland certified that the air quality from the Atlas Copco BD+ dryer is "Class 0" for humidity. This is based on test results and follows ISO 8573-1: 2010 Part 1. This classification shows the highest level of air purity. This makes the BD+ dryer ideal for industrial applications that need very clean and dry compressed air.
Conclusion: Class 0 for humidity with a desiccant dryers BD+
The TÜV Rheinland certification for the Atlas Copco BD+ dryer shows how important testing is. It helps ensure the quality and reliability of industrial drying systems. By following international standards, Atlas Copco shows its commitment to offering high-quality solutions for different industries.
This certification boosts the credibility of the BD+ dryer. It also assures customers of its great performance and compliance with global standards.
