A counter flow wort chiller chills wort that is circulating in
an inner tube while cold water circulates in the opposite direction in
an outer surrounding tube. This model is convulted, which means the 12'
of inner thin wall ½" outer diameter stainless tubing is twisted to
increase the surface area exposed to the outer cooling water. This
increases efficiency and speed of cooling. Stainless steel is more
durable and stainproof than copper, although copper has a slight edge
on heat transfer. Important
- for best results, your tap water should be 60 F. or less.
Unlike a simple immersion chiller, a counter flow chiller
needs to be rinsed thoroughly between uses to keep it clean. A thorough
flush with water immediately after use keeps it clean for the next
batch. The wort in and out tubes feature 1/2" FPT brass threads for easy
attachment of male NPT 1/2" threaded fittings. Keep in mind that brass is softer than stainless, so if you screw stainless parts into these fittings, do not over tighten, as excessive force can crack the softer brass.
The water in tube is a male hose thread fitting on one end,
and female hose thread on the other end. Be sure to set it up so the
wort is running the opposite direction of the outer cooling water. 10"
long, with a 6" diameter outer coil. A mounting bracket is welded to
one end so this can be mounted in a variety of positions.
