Made with stainless steel plates that have been fused together with solder, these chillers have small channels weaving their way up and down each plate. This creates more surface area for the wort to travel over, and more time for the water to cool the wort down. The small, compact design allows for any easy integration into any brewing setup, and takes up less space than any other chiller on the market. Cleaning a plate chiller is a bit more involved than a normal immersion chiller, due to the tiny pockets created by the channels in the plates. These pockets can harbor cold break material, hop remains, or any other solid, and if not removed can cause infection in subsequent batches. The best way to clean is to recirculate a solution of hot water and Oxyper through the chiller as normal, then backflush the chiller, bringing the Oxyper through the "Wort Out" side in out through the "Wort In" side. This should remove any particulate that may have gotten trapped by the folds in the plates.  32cm long, 7.5cm wide, and 5cm thick. The wort inlet and outlet is 1/2 Inch BSP Thread, and the water in and out are also 1/2" BSP Thread.
