MDG dryer
The MDG heat of compression dryer is the world’s first dryer that provides a stable and guaranteed Pressure Dew Point (PDP) of -40°C (-40°F) at near zero power consumption.
The unit has no heating element, no blower and there is no loss of compressed air (purge). Its total power consumption is always below 120W. Compared to market standard desiccant dryers, the MDG’s operational cost is close to zero - even at high electricity costs.

Applications
Instrument air
Air is used for pneumatic conveying during the manufacturing process, this means it comes into contact with the product so the air must be clean. During the rest of the process compressed air is also used to control valves, sorting, polishing and more.
Packaging
In the pharmaceutical industry, compressed air plays a vital role in packaging operations, including sealing, labeling, and filling. Its dry and contaminant-free properties ensure a sterile environment, safeguarding product integrity.
Cleaning/drying
Compressed air is widely used for cleaning and sterilizing manufacturing equipment and workspaces. By effectively removing dust and contaminants, it helps uphold strict hygiene standards in production facilities
Wastewater treatment
Before use, water must undergo treatment to prevent product contamination. Similarly, after use, it must be purified again before being recycled or safely discharged to meet environmental regulation
FAQs
How clean and dry does the air have to be?
It has to meet Class 0 of ISO 8573-1:2010, which is the international standard for air quality classes.
This standard defines how much of any of the three contaminant types the air may contain. The lower the class, the higher the quality of the air. Therefore, Class 0 means the least-contaminated air can be.
And to meet the requirements of a cleanroom in semiconductor production, the air should achieve Class 0 quality for moisture, oil, and for dust.
How do facilities acheive Class 0 for moisture, oil and dust?
- It all starts with the right air compressor. An investment in an oil-free unit means that there is already one contaminant semiconductor producers no longer have to worry about.
- Next, special filters remove dust or other particles from the compressed air and keep them out of cleanrooms. You will need several of them to get to Class 0.
That takes care of the “clean,” but what about the “dry?” that will eliminate the risk of corrosion?”
- For that, you will need a high-performance dryer that can reach a pressure dew point (PDP) below -70°C. This kind of PDP can be achieved with a desiccant adsorption dryer. These desiccant dryers are the optimal choice for providing very dry air for critical applications.
How is a typical CDA installation set up to keep contaminants out of the cleanroom?
- First comes the oil-free compressor. Because the production of semiconductors requires a lot of energy, it makes sense to invest in an energy-efficient model. That can greatly lower operating costs.
- Next comes a pre-filter. Its job is to catch most of the particles in the compressed air. That way, the air that reaches the dryer is already much cleaner, which helps reduce its maintenance needs. While an adsorption dryer does a great job of drying the air, it may produce some desiccant dust. Therefore, the newly dried air is then routed through two after filters. They filter out the desiccant dust and further purify the air.
- At this stage, only the tiniest particles are left. Now, the air merely has to go through one more filter. Usually, this is a PTFE membrane filter that utilizes surface filtration technology to capture particles down to a size of 0.01 μm.
Following that final step, the clean dry air can now be used in a cleanroom environment without jeopardizing the semiconductor production.
