Boilermaker Kettle w/ AutoSparge Kit Finally a sparging system that's a ''set-it-and-forget-it design''! This elegantly simple design automatically sets the hot liquor flow rate and liquid level in your mash / lauter tun. As you change the sparge rate into your boil kettle; the AutoSparge automatically responds by increasing or decreasing your hot liquor flow to compensate and keeps a constant level in your tun. Awesome for RIMS systems! Works great with gravity systems OR with pumps! Wort gently rotates on top of grain bed to reduce channeling; oxygen pick-up; and to increase extraction efficiency. WIth a constant hot liquor level over your grain bed; complicated rotating sparge arms are unnecessary complications! Float ball and rod are stainless steel. Valve body is low-lead surface treated brass. Includes 18'' silicone hose and foam hose float. Requires a 13/16 mounting hole. See installation tab for details. Fits any pot larger than 12'' in diameter including converted kegs. Adaptable to coolers. See installation tab for cooler installation.
