4 kegs with a 5# C02 tank but I opted for a 20# C02 tank:
Still in need of the 3rd ventmatic but this shows you the collar and the fan that comes on with the freezer for active cooling all controlled from the Ranco ETC.
Currently configured with all 3 taps (although I just ran out of C02 and I will be cleaning up the lines/mounting the new manifold setup):
I Kilz'd the collar since I doubt I'll be getting around to covering it in red oak as I originally planned. Pardon the few mess up spots where it dripped.
I have a 10" drip plate but I'm not even going to install it. I'm wait for a 13" wide with a 12" tall backsplash one to arrive so that I can mount it to the collar vs. the freezer itself. With the exception of the foam (a few extra minutes of work) everything can quickly/easily be returned back to normal if need be.
Currently on tap-Rogue Dead Guy Ale clone (grain/extract) and a Bavarian Hefeweizen (all extract) with some extra hops I tossed in for fun.
