Here it's Jerry rigged up to help with a beertastrophe last night ; )fastev said:Building two of these now. Marcb and I are basing ours off his 14 and 27-gallon Morebeer Ultimates, but the OP's link is basically the same thing. I just had the aluminum block made. I'll get the Peltier pads and heatsinks mounted to the blocks once I get my new milling machine set up.
Out of curiosity, what was the ambient temp during your test? I don't need lagering, but in summer the basement where I ferment gets up occasionally to the mid 70s on a hot day. All I need is about 10-15 degrees of cooling. 60 degrees would be FANTASTIC is I can get it to work that well. My controller box is now done other than final testing, and now I have to mill the aluminum plates and assemble the business end of the thing.Starting with 85 F water it took 4 hours to cool to 67 F. I raised the temp up to 71 F with fermwrap heater (took about 40 min), turned on cooling again and 7 hours later I terminated the test at 60 F.
