+1.

I have been recirculating my last few brews to see if that picked up a few efficiency points and lost a few more degrees doing so, this will help and make hitting target temps a breeze.

You will not regret the move, I very rarely use the gas powered 3V any more. 3V is kept for 100L + brews now.
Worked out mashing (25L batch) with my HERM system cost me about 25c per mash and no gas heat or carbon-monoxide.

What would be the upper sized brew you would recommend this for?

I remember back in the original thread, I think you said the copper was good for 100L batches and the S/S was good for 40L batches. Can you confirm this is still the case from any further testing, and what type of batch size/ ramp rate should I expect (approx)

Also if needed are you going to do the copper one?

edit: serious questions, I'm getting sick of the RIMS setup and am looking at this as an alternative

We have done 100L brews using this coil and the kettle (1800-2000W) element. Ramp is good for 1C per min when controlled properly. This mostly depends on the flow you can achieve thru your false bottom.
We are not doing a copper one, too hard to clean and It looks ugly.
We have designed a whole system including controller/PID , software etc. Just not ready to put the complete system to market yet.Those that have tried the system have given it 100% positive feedback.

The heating element is a $9.00 kettle from Kmart, because its heating such a small volume its very efficient, I have designed a better housing than the kettle made from 100mm PVC.
Works very well, I will post the design/measurements when I get 5 minutes.
Here is a happy snap in the mean time.
Yellow thing is the coil in the heat exchanger.

G'day Nev,

so the half inch silicon hose you sell should attach easily to one of these coils and should just require a couple of radiator clamps to hold it in place, is that correct? Or would there be a better way of connecting to the coil?


edit: You just beat me with the picture. Looks like an easy set up

Clamps are essential as the hose can slide off the coil, hot liquid and thongs dont work well together.
We didnt want to complicate the design by adding fancy connectors and it wouldnt make it work any better.
This way you can drill your holes in the heat exchange lid and just poke the coil ends through and clamp on.
Its idiot proof, I have proved that :icon_cheers:

Rough only, a few weeks. We keep upgrading the controller, thats taking the time.

So in that picture is it in the yellow pipe (plumber PVC sort of thing?)

How hard to make?
