Bleaudg - that is the most over the top untra-serious moisture management system I've ever seen. With that refrigerated air drier in there, I honestly don't think any of your filters will need to be recharged during the life of the Shoebox compressor - even if it lives a long and glorious life.
I have about 275 hours on my Shoebox setup. I dried the Wilkerson desiccant at ~150 hours mostly as a check to see how it was doing, since the beads were still very blue with no saturated beads visible anywhere. I checked the weight before and after drying, and the water removed was pretty much right on the amount that I calculated would be removed if everything was working per the math (which was good to know). The beads did come out of the drying process a deeper, darker blue than they went in, but the amount of water removed indicated that when I dried them, they had only absorbed about 20% of their capacity at that time. Since I figure I don't really want to go much over 50% before drying again, I should only need to dry them about every 375 hours . . . .
And I don't have a refrigerated dryer before them! I expect you could more than double the time between drying your silica. And your Daiblo sees so little remaining vapor that it will last pretty much forever too - assuming that you too have shut offs in line that separate your driers from the air path when not in use . . .
I will say that had I found ANY evidence that my system was still passing sufficient vapor that condensation would occur, my plan was to replace the silica beads with molecular sieve beads and be done with it. But I have not done so as there was no need (but I still might at some point just because I can for about $70 or so). In your case you could do that, sell the Diablo, end up with the same air quality, come out ahead financially AND reduce your fill times with the Shoebox since you don't "waste" run time pressurizing the Diablo every time - that should increase the usable life of your system.
Here is my set up. I do remove the cover and have the fans to the left blowing over it while running. I use an electrical timer to control the runtime.
