There are a few discussions on this on the Home Brew Talk forum. Lots of different solutions using PC fans and tubing and even glycol. These would be from people in pretty hot climates, so I wouldn't get too fussed about it.
I'll take a pic for you tonight - but yes to keep the lines cool, helps reduce fobbing i assume.
Nice one - thank you - my bar is a 21ft x 10ft cabin in the garden, i have aircon fitted for when I'm in there, but when I'm not it gets pretty toast in there so i think a fan will help, that being said, this kegerator will end up in the shed, the bar is already full, I've got a Heineken David, the Mangrove jack a Carlsberg draught master, 2 Heineken blades and a treble door bottle fridge in there
That could get warm alright. Even with just what the fridges give off. But I still think insulation rather than cooling is the answer here. If you think about it, the volume of beer in the hose that's in the tower would be less than 0.002 of a pint. The rest of the hose is in the kegerator and therefore at the same temp as the beer in the kegs. There may be a little fobbing at the start of the pour as that section cools down, but that should be negligible.
I think it's in the Kegland series X units. This photo from their website seems to show it. Looks like a tight fit to get your beer lines up there too.
