Chillzilla Counterflow Wort Chiller

SKU: 7518
7 Review(s)

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 fermentor) 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.

great Review by Brewschneider
This chiller lowered the temp of the wort to 70 degrees in the time it took to empty the brew kettle!!! Very pricey but wow does it do the trick! (Posted on 7/16/14)
Chiller works greats Review by Roger
I gave myself a birthday present. I bought a piece of brewing equipment that brings 5 gallons of fermented beer (wort) from boiling to room temperature in less than 10 min.

The Chillzilla is bigger than is shown. The outside diameter is about 6 inches. It sits outside the brew kettle. It used hoses to connect it to the brew kettle, the faucet, the carboy, and the sink drain.

It’s a copper coil in a copper coil. The wort flows through the smaller coil and cold water, from the faucet, flows around it. It is called “counter flow”, because the water flows in the opposite direction of the wort (wort flows down, water flows up).

Great chilling, but poor connections Review by Thayer
I knew when I ordered this that it had straight copper tube for the wort out (instead of matching the 1/2" MPT wort in), but I ordered it anyway because of the Chillzilla's legendary cooling performance. Still, it makes no sense to me why the manufacturer uses two different fittings for the wort line--they should either commit fully to a certain kind of fitting, or commit to none and leave both the wort in and out as straight copper tube.

Now on to the actual units I received. My first unit had the same problem as Dennis--the water inlet was so bent that I couldn't connect a hose. It also had a really pockmarked wort line, which to me was a sanitation disaster waiting to happen. So I returned it to Northern Brewer, and got a quick replacement via their customary great service.

My second unit didn't have a bent hose inlet or a pockmarked wort line, so it was great on those counts. However, one end of the brazed-on mounting bracket was already loose when it arrived. I didn't think much of it because I wasn't planning on mounting the cooler, but by the time I changed my mind on that three weeks later, the bracket had completely fallen off. A welder friend said that the brazing looked pretty chintzy. The stainless bracket hadn't been melted at all, and it looked as if the "brazing" consisted of just melting the brazing rod onto the copper tube and sticking the stainless bracket into the pool of hot metal. Anyway, now the cooler has a bunch of sharp bits where the bracket used to be attached, so it needs to be fixed one way or the other.

I'm happy to again mention that Northern Brewer has been great to work with throughout the process (they offered to either replace the second unit or give me a generous credit to fix it myself). However, considering the price, the Chillzilla is not as awesome as I would expect. It misses on the little details that earn products 5 stars. In fact, despite the awesome cooling and easy cleaning, it suffers from enough manufacturing defects and poor execution that I can only give it a 3. (Posted on 10/2/13)
Ok Review by Dennis
I had to go through 3 to get 1 that the hose fitting was not bent to the point I could not get the hose connected. NB was great making sure that I got what I needed. I wish that it had a way to connect a tri-clover sanitary fitting without threads for both in inlet an outlet. (Posted on 9/12/13)
Chiller works great. Review by Joel
The chiller worked very well, it took my wort by full flow gravity feed and cooled it from boiling to 87 degrees at the discharge of the chiller. It cleaned up very easily. I rigged up a smaller stainles bucket with a bulkhead fitting to feed the chiller, then put a double basket strainer on the bucket pouring the wort into the strainer draining into the bucket and feeding the chiller. I accomplished transfering the wort in about 6 minutes. Previously I used a bag full of ice in the wort and the bucket with wort in it sitting in a water bath to cool the batch which took about 15 minutes. This was much faster and much less chance of contamination. (Posted on 9/9/13)
Works fine but traded in for a plate chiller Review by Steven
Im not sure if was using it right - likely had the valve from my brew kettle open too much. I got impatient and ended up returning it as i really wanted a plate chiller in case i wanted to do bigger batches. I researched this thing alot and spoke with alot of staff at NB so im sure it works fine!! (Posted on 7/15/13)
Very good chiller Review by mmmbeeer
I've been using the chillzilla for a few years now, and can say it does what it's supposed to do extremely well - 5 gal of wort down to fermentation temperature in <10 min. Big improvement over my previous immersion chiller.

It's very easy to clean - simply flush with some hot PBW solution. Since it's just a copper tube, it really doesn't have any small spaces to trap particulates.

One minor complaint is the 1/2" straight copper tube on the wort outlet. The inlet has a 1/2" MPT onto which you can easily thread a barb connector. Why they didn't do the same for the outlet is puzzling. To correct the problem, I just added a 1/2" MPT compression fitting and a barb. You could also solder on a connector, if you're good at that sort of thing.

Cheers! (Posted on 10/15/10)
