I used my Duda Diesel 30 plate chiller yesterday for the first time and absolutely love it. I brewed 3 batches (20 gallons total) yesterday and the 10 gallon batch was cooled from boiling to 70F in less than 10 mins.
I was pretty worried about it getting clogged since it was the first time I used one, but I just ran my pump into my paint strainer for the last 20 mins and then whirlpooled the last 10 which hopefully filtered out alot of debris.
Anyway, I never had much luck with the IC so its going into retirement.
