Upon arriving at the fork of plate vs counter flow chiller, I opted for the hose wrapped, copper tubing counter flow. Because A) I could make one and B) It was cheaper. It worked wonderfully! Wort went in hot and came out cool, what more could you want? Well, call me finicky but as someone who spends my paid hours designing parts that both work well and are easy to use, the trusty old coil HE fell short. It was chaotic to arrange, hoses everywhere, had to be leak checked frequently and for its purpose, took up too much damn space in a home brewery which strives to fit on a single rolling stand.
Off to Amazon! After a bit of specing, I ordered Duda Diesel’s B3-23A-20ST plate heat exchanger, an NPT thermometer, an NPT tee fitting and some NPT barbs. ~$150.
One big incentive of this switch was the ability to monitor wort-out temperature. There are a rare few months in Texas’ inviting climate when ground water allows pumping directly to the fermentor. Excited to use this weekend on the next iteration of the Never Ending Hefe with unrestricted fermentation.
