Grainfather's large counter flow chiller, spare part for Grainfather G70. The cooler can also be used with other brewing methods, if you don't have a Grainfather.
Delivered assembled with hose for wort, cooling water and hot water, as well as coupling for incoming wort.
The counterflow cooler consists of an inner tube for wort and an outer tube for cooling water. Wort and water travel in opposite directions, and the wort is cooled as quickly as it flows through the cooler. The temperature is regulated by adjusting the flow rate of water and wort. Start by turning on the cooling water at a moderate flow before turning on the hot wort, to prevent expansion of the outer plastic hose on the cooler.
