A NEMA 10 receptacle has no ground, so your brewery would only have the two hots and the neutral available to it. You could run 120v and 240v items from your control panel, but you would still want some way to add a ground to your control panel.
edit: this is one of my complaints about high gravity's equipment (the other complaint is their prices). your solution to replace breaker and outlet addresses your problem, but doesn't address the fact that the high-gravity equipment uses the neutral as a ground.
