This immersion coil Wort Chiller is made from 12mm(od) microbore Stainless Steel tubing and is used to quickly cool the boiling wort to yeast pitching temperature, by acting as an efficient heat exchange system transferring the heat from the boiled wort to the cold running water passing through the chiller. It is a simpler and much less expensive system than either a counterflow wort chiller or the plate chiller system, but is very effective nonetheless.
It doesn't come with any form of tubing or fittings to allow you to connect it to a suitable tap or water supply, so you have maximum flexibility in determining how you intend to use it (ie directly to a tap or onto the outlet of a quick serve tap or drum tap if you are using a large fermenting bin as your water reservoir). The outflow from the chiller will need to be placed directly into the drain, a sink or a collection vessel (so you can use the hot water for washing all your equipment) but EXTREME care should be taken as the temperature of first outflow runnings can be as high as 80ºC.
Many brewers find that this coil works more effectively if the water is input into the bottom of the coil and then drained from the top. This is because the cooled wort is always towards the bottom of the boiler rather than at the top where it could be reheated by the convection currents rising from the hotter wort below it.
Depending on the temperature of your feedwater and the rate of flow, it is possible to cool 25ltrs of boiled wort to yeast pitch temperature in approximately 30 minutes.
The chiller contains approximately 6.3m of 12mm (od) microbore stainless tubing in 10 coils, is 25cm high and has an outer coil diameter of approximately 19cm, so will easily fir into most standard brweing kettles and converted tea urns.
