The bar fridge is a 115 Lt Fisher & Paykel and has an internal shelf at the back which fits the 2.6kg gas bottle at 45 degrees with flexi reg tube to the reg (bottle & full size reg don't fit with direct connection), and the 19 & 4 kegs at the front. A tight fit for the 19 height wise with 10mm to spare but she works a treat. When kegging from the fermenter I fill the 4Lt then the 19Lt, give them both 60kpi & disconnect, cold crash both overnight, connect the gas to the 4 the next morning @ 50kpi and she's cold, gassed & ready to pour that afternoon. The gas then goes onto the 19 and it's gassed in a couple of days to fill the 4 'tap' keg as and when required. I bottle the last few litres in PET bottles to have a couple days supply when kegging again. Up to Brew 9 and haven't had to buy a carton of tasteless commercial beer since so the setup cost is all but paid off and it's a buck a litre from here on - Bloody bewdiful mate!
