Ten-gallon gravity three tier system. Everything in the system was designed to keep brew day easy and clean-up as simple and easy as possible, ie:
Gravity fed (no pumps or other equipment to clean)
Immersion chiller (no plates or CFC to clean)
2 tap keg fridge with room for 2 additional carbonation kegs
Custom fermentation chamber with Ranco two-stage controller for heating/cooling cycles.
Obviously efficiency is a little lower than more complex systems, I bump up the grain bill a little for each batch.
