This heat exchanger is a special tube in shell heat exchanger developed specifically with modern brewing in mind.
with inside tube diameter of over 1/2 inch, it insures this heat exchanger will never clog up, or foul up with trub or hops. It has enough surface area to cool 20bbl batches and is super efficient. I would chill 7 bbls with about 5 bbls of CLT water. The multiple tubes within the shell increases surface area while maximizing flowability. This exchanger can completely change your brewing practices and speed up your brew day. think about the possibilities of not having to wait for your kettle to drop out before changing temperatures.

2 in tri clamp inlet and outlet, 1.5 inch connections for the water inlet/outlet
