Immersion wort chillers are great in that they are easy to clean and easy to use.  However, having the cooling water hoses attached all the time gets to be tiresome, as you have to deal with the chiller with long hoses full of water once you are done cooling a batch. Our new Modular Immersion Chiller solves this problem.  No more lugging around a chiller, cleaning it, and storing it with the unwieldy hoses attached.

This 25' stainless cooling coil features quick disconnect hose fittings, compatible with Melnor and other quick disconnect hose systems.  Best of all, because it is easy to connect and disconnect,  It can be adapted to a wide variety of purposes including connecting two in series so you can pre chill your cooling tap water in an ice bath in the warmer months before cooling your wort or still head.

For use as a pre chiller in areas with warmer tap water, hook up two units in series with the first chiller in an ice bath, and the second in your wort. Or if distilling, use one Modular Immersion Chiller to pre chill your still head water, connected between your tap water source and a still head with quick disconnect fittings like our items C74 and C75.

Fits most boiling pots, as well as the Mash & Boil, Grainfather, Brewzilla, and Robobrew. It fits ½" interior diameter tubing (not included, see our optional discounted Chiller Tubing Kit). 15½" tall to the inlets and outlets, and the coil is 7¼" wide.

This also works great as a pre chiller for a wort chiller. Just pipe this coil into your cooling water supply line and pipe your wort chiller into the exit.  Then place this in a 5 gallon pail full of ice and water, and you can chill wort even in Florida or Hawaii on a hot day.

Note: Connection tubing is not included, see our product Q74 for a tubing connection kit, or shop Melnor Quick Disconnect hose fittings at a local hardware store.

This is a nice chiller. The coil is a larger diameter and at 25' it chills as fast as my 3/8 50'. It has nice disconnects. I would recommend the upgrade which comes with hose and disconnects

Nice and flexible

Review by John on 11/1/2021

I love the quick disconnects so I can use this as both a pre chiller and immersion chiller. Good for prechilling my still water in the summer.

needs better fittings

Review by Paul on 10/29/2021

Hose fittings that are included are too short to work with readily available garden hose disconnects. You need to hold your disconnects in place manually to get any flow, and this causes leaking. Otherwise they are too short to engage the valve on a regular garden hose disconnect and so you get no flow. Williams needs to either change these fittings or include disconnects that will work with these fittings. William's Brewing Responds: There are two competing systems of quick disconnect hose fittings out there, and it sounds like you have the ones that are not compatible. Our chiller is based on the popular Melnor® line of quick hose disconnects (sold at Home Depot® and other large suppliers). For a description of these, see this link: We have tested the above fittings and they work fine. We also sell fitting L19 that fits this chiller.

Leaked on first usage

Review by Craig on 9/23/2021

Material looks & feels to be high quality. Hooked it up to garden hoses to test BEFORE first use because I didn't want any garden hose water getting brew. Item leaked out of both fittings immediately. Not the garden hose quick release joints but the chrome looking tube sleeve joints. Tighten both fittings ... still leaked. Ended up taking fittings off and using food grade high heat silcone to make proper seal. Seems fine now.
