I just wanted to post some information in regards to building a homemade counter flow chiller. Please see the below link for parts and instructions on building a CFC that doesn’t require soldering. I felt this was the better alternative because the unit can be taken apart for cleaning and what not.
Mike and I built a CFC based on the above link and tested it last night. We boiled about 7 gallons of water and then ran it through the chiller. With about a half turn on the water line from my house, the entire volume of water was cooled below 64degF in about 15min. In reality, it probably took 10-13min, but I’m being conservative here.
Since I bought a bunch of other random stuff with the materials, I’m not quite sure on the total cost yet. Although, I’m extremely confident that building your own will save you a lot of money versus buying a CFC. Plus, who doesn’t like building stuff!
We also made our own flow through thermometer to help us gauge our out temperature. I will post something on how to make this shortly…..
