Have a B3-23A 30 Plate chiller from Duda Diesel w/ about 8-10 batches through it. Only reason for selling is we upgraded to a bigger version! (we do 15-20g batches and quite a few lagers).
Fittings are 1/2" Male NPT all around. I plan on keeping the elbows, QDs, etc...so this is for the chiller only
