Nano D2 Series Desiccant Air Dryer Obsessed Garage

We’re getting really sophisticated here, bros. My good friend Scott Ales owner and founder of YoungTimer (an automotive restoration service), has introduced me to these high-purity compressed air dryers that are definitely overkill but freaking awesome. 

Not everyone will need this, and I get it, but for those of you who want to remove moisture from your air distribution system completely, this compact air dryer unit is what you’ll want. We recommend the NDL 090 paired with the Evo II if you are not in a dry location, with around 40% relative humidity.

If you don’t know this already, taking the moisture out of your air prevents condensation from forming and freezing, clogging, and jamming your machine. A machine like this is beneficial and something you’d have for the rest of your life. 

The way these things work is they use a heatless twin tower configuration housed in a modular design. Wet air from the compressor aftercooler enters the dryer and is directed into one of the columns (Column A).  Air passes through the desiccant bed where moisture vapor is ADsorbed (not ABsorbed). The dry air then passes through a particle filter that retains desiccant particles. All this sounds super-scientific, and it is, but it works and fascinates me. Simultaneously, a small amount of dry air is counter-flowed down through cartridge B and exhausted into the atmosphere, removing the moisture and regenerating the desiccant.

These dryers are controlled by a PLC (programmable logic controller), which will periodically switch the solenoid valves, reversing the function of each column and ensuring the continuous supply of dry air. 

Don’t be intimidated by all of this; just trust me and know that I’ve seen it first hand, and it works exceptionally well. The small footprint of this unit takes up a lot less room compared to other dryers on the market. From my experience, this is the biggest benefit of owning the nano.   

I’ll be carrying the NDL-070, NDL-090, and NDL-130. Check out this Nano D2 Series Desiccant Air Dryer brochure for sizing and specs.

There is also an option to add an Energy Saver Kit. This kit allows the user to see dewpoint readings and shuts the air compressor off when the air hits a negative 40 degrees dew point. Check out the Energy Saver Kit Installation Guide for more info.
