Looks like a compressor cooled unit. If so, there are some extra things that you might want to consider doing to prevent it from dehydrating your cigars. See post #6 from GoatLocker here:

I'd also recommend ditching the kitty litter and getting HCM beads from CigarNut, they are much more stable and much faster to react to changes than KL.
Aside from that, nutcracker brings up some good points.
