From my previous write-up on chillers:
" 2) My personal preference is immersion chillers. Counterflow chillers and plate chillers will get you to pitching temps faster but the immersion chiller can get you worth chilled down below 140 the fastest. To use an immersion chiller you simply place the coil in you worth 10 minutes before flameout. At flameout you run hose water through the coil and, via heat exchange, the coil sucks the heat right out of your scalding hot creation..."
If you prefer copper you can find a 50' copper immersion chiller on Amazon for $63.99 by clicking HERE.
