Got two 35 gallon Norwesco inductor tanks that I'm converting to conical fermenters. Got the idea awhile back and saw that other brewers had done the same thing, that bolstered the idea.



Stand is 3/4" plywood top with 2x6 frame, very over engineered to hold the weight of two full fermenters.


I used foam insulation for HVAC tubing split and put around the opening to cushion the plastic to wood contact.


These have 8" screw on lids that seal, the center of the lids has a pop out that I will use to install a stopper and airlock.

Bottom view of the angled bottom and 2" threaded opening.


Plumbing parts. 2" to 1 1/4" reducers for bottom opening and 1 1/4" valve for bottom dump. 1/2" valves for racking arm and top fill opening.


Tubing. 1/2" reinforced tubing to connect top fill valve to where I brew in the garage. Will be used to pump hot PBW, StarSan, wort from garage to conicals. Gas line will connect to the 2 way manifold at the conicals to allow for purge before filling with wort and when dumping trub making this a completely o2 free environment.

Awesome. I've been kicking around the idea of doing this for a ~15 gallon setup. Can you make a little list showing part numbers and prices for reference?

I'll pull together a parts list, most of it was McMaster-Carr and a bit from B3, and likely several trips to Home Depot.. :D

I brew ales and my basement stays a pretty steady 65-68 most of the year, beyond that there are two heat pumps, one for each room down there. I can either heat or cool if I need to. If I were doing lagers I'd insulate them and put a copper coil in there, run glycol to the keezer and run a temp controlled pump.

No, I got those from the place where I bought the tanks in Griffin GA, Newton-Crouch. Figured I'd best get them there as they aren't that common.

Any updates? Are the conicals air permeable? Do you have to worry about oxidation to the beer? I'm thinking if you let it sit long term as in Barleywine or lagering...

I have a post somewhere with all the hardware for a 110g inductor tank build. That should get you started, just change the sizes to fit the conical you buy. Should I link it? No pics, though.

Ya, that would be great.

There are a few micro breweries using these 100 gal tanks. I am interested in how long they can be used for primary/secondary/serving.

Found it- here's the parts list for the 110g inductor tank build. They're very popular with small startups, I know Mike Hess has been using his for 2 years without problems.
Any chance I can grab that parts list? Been interested in trying this.
