Brewers that use an immersion chiller, plate chiller, counter flow chiller, or a pump should know that recirculating the wort back into the kettle to whirlpool the wort makes for much faster cooling. An immersion chiller will also make a concentrated pile of trub and hop particles in the center of the kettle bottom keeping it out of those impossible to reach areas of the pump, plate chiller, or counter flow. This return attachment should be installed higher than your wort level so that it can extend down the side wall of the kettle before curving to the side to force the recirculated liquid towards the sidewall and around in a circle. The end of the dip tube is slightly bent to make a better wirlpool. Full weldless installation hardware is included. 14" height.
