You insulated your air exchange box well except at the shanks. You may want to avoid going through a thick space such as a 2 x 6 ???. Minimize the amount of area that can transfer heat into the shanks while still having a surface to tighten the shank nuts onto but still stout for stability.
Have you insulated the outside of the conduit between the keg box and the air exchange box? Difficult to determine if this is wrapped or not.
