 Chillzilla Counterflow Wort Chiller
Three features set the Chillzilla apart from conventional
counterflow chiller designs — the first is an
all-metal construction. The excellent conductive properties
of non-rusting copper tubing give the Chillzilla outstanding
heat-transfer capacity.
The second is an inside tube (which carries wort from the
kettle, through the chiller, into the fermenter) that is
convoluted into an elongated spiral. This shape enhances
the chiller's efficiency by creating turbulence in the
cold water flowing through the outer tube and increasing
the surface area of the wort that's exposed to cold
water.
The third is the large (1/2-inch diameter) copper tubing
used for the inside tube, which increases the flow rate
and decreases the chilling time.
The bottom line: the Chillzilla cools wort very fast
with a smaller amount of water; five gallons of wort
can be cooled in under ten minutes (or less if you're
brewing in a Minnesota winter).
The Chillzilla is very easy to sanitize using boiling
water or Star San (or a combination). Another bonus is
its compact size — unlike the bulky counterflow
chillers of yesteryear, the Chillzilla measures just
10 inches from top coil to bottom coil, and 6 inches in
diameter. It even comes with a bracket for optional
permanent mounting.
Needed but not included are 2 to 3 feet of 1/2-inch ID
thermoplastic tubing (#7128), 2 to 3 feet of 1/2-inch ID
vinyl tubing (#7106), and a 1/2-inch FPT to 1/2" barbed
fitting (#P010). You will also need to supply two
lengths of washing machine hose (available at any
hardware store) for chilling and waste water.
