I was asked to post our setup for our plastic tanks with parts. We use 3 polyethylene cone bottom tanks. They hold 10 barrels full, so we ferment 8 barrels in them.
Hardware:
We purchased three 10 barrel polyetholene cone bottom tanks from plastic mart.

There was a price break for 3 tanks. Three tanks cost the same as 2 tanks.
For $32 They installed a fitting in the cone for my racking cane. All the fittings are 2" pipe thread.
In the bottom and side fittings, I installed 2" x 2" TC x Male Pipe Thread Adapters:
On the side of the cone I installed a racking cane to the 2" tri-clamp:
On the bottom I installed a 2" to 1.5" reducer:
And a 1-1/2" 90° Elbow TC:
I used Econo 1-1/2" Butterfly Valves TC:
In the top I installed a CIP Tank Stationary Spray Ball 1" Female NPT:
Sealing the lid:
The lid screws into a black fitting that is threaded on the inside that the lid screws into fitting that is screwed down to the opening in the polyethelene tank. I took it off and put a silicon gasket around the edge (the gasket went around the edge and it seals the top and bottom) then I screwed it back down to the opening in the tank. Screwing it down tight sealed the fitting to the tank and since the gasket goes around the edge and on the top and bottom, when you screw the lid down it seals also.
I used the Lid Gasket for 7.3 Gal. Conical Fermenter Approx. 11.5" ID x 12.75" OD.
Cleaning:
We clean the tanks with 170 degree caustic (5% solution of Sodium hydroxide) circulated through the spray ball for how ever long it takes to clean any bio mater off from fermentation.
Sanitizing:
We sanitize the tanks with heat. I pump 30 gallons of 175 degree into the bottom of the tank, then hook it up to circulate through the spray ball. I set the lid on lose at first, because the air when heated will expand too fast for our 1" vent (the blow-off hose). I circulate the hot water until the whole tank and all its fittings are above 160 degrees to pasturized everything. Also when I pump the 30 gallons in hot, is submerges the racking cane and all fittings and heats them to 175.
Cooling:
Since they are not jacketed, I have each fermenter in a box made of 1" styrofoam. They measure 4'x 4'x 8' high
I put a small AC unit in it with a controller that is next to the fermenter with insulation over it. The controller turns the AC unit on and off based on the temp of the wort. That way I can control the fermentaion temp of each fermenter.
I just use the old homebrew controllers I have.
I hope everything makes since
