The Fermentap Wort Chiller is unlike any on the market today. The coils have been specially positioned to be at the top of your wort, where the majority of the heat will be. This results in a faster cooling time over chillers with lower coils. 50' of 1/2'' copper tubing with connection fittings for garden hoses. Use with converted kegs and most kettles used for 10 gallon batches. The measurements are: Approx. 10" diameter, 13" to the top coil, 24" to the bend to go over the lip of the kettle.
