Overall, I had 3 5-liter dispensers in use that were not pressure-tight all. The CO2 was initiated via a side bay with plastic hose connection. My plants Biermaxx, Tarringtonhouse and Syntrox Germany, price range 120 .. 140, spent between 2 to 6! Carbonic acid cartridges each 5-liter keg. The beer was carried out by a "plastic bottles". Zapf Results: Poor. Here at last a satisfactory beer dispenser! Carbonic acid cartridge is connected directly to the spear-body, is however in the refrigerator. Pressure control not scaled, thus own timing marks required. Approximately 1.2 .. 1.5 5 l drums with 1 cartridge to operate. Good cooling at Barrel precooling. Refrigerator drainage to the drip tray. Beer spout easily separated for cleaning the tapping structure. Conclusion: At last a system that meets my expectations! Unfortunately, in the description only South German beers were mentioned. Here, however, are also "Sauerland" beer kegs as Veltins, Warsteiner etc that I Journal with success. For repetition: Highly recommended !!
