The controller is a BCS-460 or 462.
http://wiki.embeddedcc.com/index.php?title=Main_PageAbove is a wiki link for the controller. The thing can do A LOT. it could be used to run your brewery from filling your HTL to fermentation.
You could even use one to automate your house...turn on and off lights, run your furnace, etc.
The controller can be built anyway you'd want it, but I think 9000-10000W would be a max. I don't see anyone having a 60A breaker in their houses specifically for an electric brewery! I don't know if you've seen a heavy gauge welding cable, but the diameter is pretty cose to an inch, and that's the size wiring you'd need from your breaker panel to your controller to handle that much amperage.
After thinking about the BCS controller plans, I would be very hard pressed to build one in your timeframe Steve. I just hit a big project at work that will consume a lot of my evenings and weekends from here to Christmas, and I'd really hate to delay your brewery. I'd really rather take my time building the first one, and could build something quicker, with a build template, after the first.
You might want to consider the EBC-3 or another affordable controller for the short-medium term. Use it for a while and figure out what's lacking. Then, if you still wanted to go with something like the BCS-460 or 462, I could build you one at that time. I'm sure you wouldn't have a problem selling it.
