50-10000L micro brewery system

This is a 1000L brewery system. The design comes from German style. Grain mashing and wort boiling share one same tank. Lauter tun is placed over whirlpool tun. In this case, the wort after lautering can run into whirlpool tun by gravity instead of pumping, which can avoid negative pressure forming in lauter tun. Do you like this design?
