Greetings all
Need some draft advice if anybody's got any ideas. Got a 7bbl brewpub going on down here in Argentina. We've just opened recently & immediately are having problems with the draft system. The set-up is as follows. Serving directly from our 7 bbl jacketed brite tanks. Using 6 brand new shurflo beer ace II beer pumps, one for each tank. The brewery is in the basement of the pub so beer pumps seemed like the logical choice. Currently only serving off of 4 of these tanks. Two are on a wall closest to the hole going up, directly under the bar....the draw length from these is about 2.5 meters (10ft or so), with regulator pressure at 18 psi. The other two are on the far wall, controlled by a separate regulator with a draw of 5 meters (20-25ft), @ about 50 psi. Both sets of tanks have different regulators but feed from the same tank. We have also insulated the beer pumps with a McGyver style use of large insulated tupperwares mounted to the wall with the beer pumps inside & a coil with glycol to keep them cool.
The tanks on the near wall pour fine for the first few seconds, so the tower must be adequately insulated....& then pour nothing but foam for a pitcher or two, & then pour fine. If used often enough they seem to continue to work fine. If left alone for 15-20 min, the same problem returns. The other two from the tanks on the far wall, pour slower & with minimal foam issues. However they will both 'spit' at random times, for some unknown reason. I can only imagine what problems will unfold when we start serving off the other two.
The two ideas running through our heads is faulty regulators (they are all old, & or cheap), the other is that the tubing we got for the glycol could be too thick walled and not cooling the draft lines enough. If anyone has any thoughts let me know. thanks.
