hello brewers,
I"ve almost finished my two stage stainless CFC. Tested it this arvo hooked up as one stage chiller on a bucket of 70deg water and the water coming out the exit was about the same temp as the chilling water so early tests show that it works. Next lot of tests will be using a Bucket of ice water and a little brown pump on the second stage of the chiller. Its designed so the first stage of chiller will be done with tank or town water and the second with a glycol loop. The first stage is approx 6m long and the glycol stage is about 2m long. The theory is that I should be able to chill straight to lager temps in summer in Brisbane. The only thing left to do is attach tri clover ferrules to the inlet and out let of the chiller. It is constructed from 3/8"OD stainless tubing with 5/8" ID hi temp rubber hosing on the outside. The hose is connected to 5/8' copper fittings and reducers then soldered with food safe solder to the stainless tubing. Soldering the copper to stainless was challenging at first but very easy once you know how. I wanted a stainless inner tube so I can use a range of different cleaners and keep it extremely clean on the inside. The diameter of the coil is quite large and this is so it will fit under my kettle once the legs of the kettle are attached.
