I had not seen a flat lid on a Blichmann, but on the web site it looks like that is the 7 gallon one.
The 14.5 I have works very well. Had it on a makeshift platform for years, but used a discount to buy leg extensions and casters, now I can go wherever, out of the way. It can take up to 3 PSI, so that would push the beer up 7 ft. high.
A 7 could be placed on a shelf or a table, so you could dump trub, harvest yeast, and rack out of it.
I’ve had my eye on one for awhile. I’m not normally a fan of the hundred-dollar mousetrap, but I believe the Fermenator will help me make more consistent/stable beer and higher quality IPAs and lagers. It will also reduce a significant amount of cleaning/sanitizing. As I get older, the unit will allow me to complete eliminate the lifting of carboys and kegs.
I was waiting on to pop up on the forum, CraigsList, etc., but I don’t see them too often.
I’ve made a few decisions on mine:
Even though I usually only brew in 5 gallon batches, I might as well go for the 14.5 gallon model. Not only does it allow for brewhouse expansion, but I sometimes squeeze out 10-12 gallons of session beer.
Tri-Clamps are definitely worth it. Working in the Food & Bev industry, I can tell you that stainless threads are a PITA to clean and keep clean. They also gall after awhile, so eventually you won’t be able to hold pressure or screw on that bottom valve. TC’s will make quick work of cleaning, changing out parts, and allow your vessel to last pretty much forever.
I don’t think the leg extensions are necessary because you can pressure-transfer. The casters, however, would be nice, but I think I could build them or a transfer cart.
Blichmann recommends controlling ferm. temps with a fridge, but I think it will be easier to use a chiller loop with an internal stainless coil or externally-wrapped coil. This way, I save on space and don’t have to lift the unit out for cleaning. I haven’t worked out the specifics of the chiller loop, but I’ll either build its own loop with an old AC unit or use a recirc pump and a keg of chilled water.
OK this one says it is pressurized for CO2 pumping. Does that mean I could just hook up my CO2 bottle and deliver it to my keg or bottling bucket instead of shelling out another $150 for a pump or $130 for leg extensions?
