Chill your wort without worrying about your hop additions clogging up the works! This HUGE counterflow heat exchanger is made from fully passivated 304 stainless steel with 1.5" TC (sanitary) connections on the wort side and 1/2" BSP on the cooling ports. Plate chillers are great for their high efficiency and compact size, but if there's too much hop matter in the wort running through them they can quickly clog up. Transferring wort from your kettle to your fermenter is one of the critical steps in the brewing process where you don't want any hiccups. This stainless wort chiller can withstand high hop additions without clogging issues and has a higher chemical resistance than copper chillers.
