Stainless Counterflow Chiller
« on: April 18, 2019, 01:56:03 AM »
I've been telling myself for years that I was going to go all-stainless (on the cold side, you can pry my plastic mash tun from my cold dead hands) and finally figured out a way to make it happen on the cheap.

It may not be the most elegant of chillers, but did I mention cheap? ;D

But Sean,  did you ever find a stainless connector to replace the carbon steel in your spunding valve?   Inquiring minds want to know!  (I know, those are very old posts...)

*Finding* it isn't the issue... Justifying it on the other hand...

Yikes.  I always wonder when the word "yikes" is really appropriate.   Yup, this is it.


PS my valve uses all brass parts.  ~$20 from Amazon for the CD PRV you used and a gauge,  about $11 at the corner hardware for the rest.  The PRV is brass anyway.   Just sayin'.

I definitely don't see the issue with non-stainless hardware there. If there's beer in contact with it, something has gone badly wrong.

For $20 shipping, are we talking the full marching band to deliver it or just the drum corp?

Sorry, I know this is way OT now, but, another reason not to go with that way expensive part.  My cheapo build also used a SWIVEL connector. (Pictired, that's tee, to NPT-to-flare adapter, to flare swivel connector.  Nylon flare washer in metal to metal flare connection, I just use a lot of gratuitous thread tape.)  Minor detail maybe, but handy to make sure everything can be tightened up and still have the gauge positioned conveniently.  Back to topic, nice new build Sean,  and good to see you maintaining the blog again on occasion.  Congrats.

I have been using the same plastic MLT for years and am trying to justify spending the $$$ for a shiny stainless insulated purpose built piece with a built in manometer. Oooh. Ahhh.

I’m like you: I just can’t bring myself to pull the trigger and get rid of “that damn blue cooler” as Annie said about Denny’s.

Did you build the CFC?

PS. It looks great to me.

Looks good - how efficient is it?  I have stainless CFC but run through a pump and recirculate with a SS WIC also... but I am sure that copper is quicker.  Yes?

In any event - Cheers to a nice build!
