DIY Chillers

Just phoned MetraClark in Pretoria West
They will supply to me at just below R400 for a 15m roll, 3/8 " dia

Now I just need to find the time to drive there in office hours

One more question though: I am guessing 0.61mm wall thickness is OK as I am not planning on high pressure application for the exchanger

It's fine - there isn't really any pressure as it is an open system.

All I can say is respect to Simon's work. It is not very easy to do such a neat coil setup

Thanks

I've had enough practice. I've built enough of them

As a matter of interest this is the chiller I made for my 5 liter batches. The one end is attached to a submersible aquarium pump which is placed in a sink full of water and blue ice bricks. The return just pumps back into the sink.

Feebleness has little to do with effectiveness (or looks)

A Porsche doesn't get you through Jozi traffic any faster than a Hilux does.

So he says! Without a pre chiller it cooled down both pots to 23 degree is 20 minutes. This is the stuff that makes us thankfull!

That photo could have been taken in my kitchen as we have the exact same double sink and mixer...

In between fighting small children and beer projects Brett collected his artwork.

Hope it works for you.

Not only the chiller, also a bottle of jalapeņos saison and a bottle of stout! Very much enjoyed! Will reciprocate soon!

So which copper tubing size should I actually use? 3/8" or 1/2". The 1/2" fittings I can buy at the general hardware store. Never saw any 3/8 around.

[SimonB Administrator Find all posts View Profile Close SimonB]

1/2" is normal plumbers fittings. 3/8" is for industrial cooling and refrigeration. Use which ever you want, but 3/8' has more surface area per unit volume of water flowing through it - more efficient.
