One More Wort Chiller

[Zwickel]

Hi Brewmates,

just wanna show you a superb wort chiller,

here a pic of it:

Basically that kind of heatexchanger are made for solar-systems, made in Korea.
I think you may get that part in Australia as well, thatsway Im posting here.
That part is very popular here in Germany and used by many homebrewers.

the chiller is made by stainless steel and has a incredible efficiency.
there are 20 chambers in, to increase the surface.

Im cooling down 70l of boiling wort within 20min to 10C.

For hot days, when the cooling water is not very cold, Im using two of them in a row:

one can get it here:

and here:

just to show you how much it cost...

Cheers

Hi Zwickel,
That looks good. Price is good too. Have you had anyproblems with break or hop material clogging it?
cheers

$1146au?
or buy now for $1479au, is this correct?

Thats a pretty impressive looking chiller. The price is pretty good as well, but does the fact that it has been welded with brass not cause a concern about lead content? I know that brass can be pickled with a mixture of Hydrogen Peroxide and vinegar to leach the lead from the brass surface, but there are differing opinions about whether this creates surface porosity leading to further leaching of lead from the brass anyway, defeating the purpose. Has anyone got any comments on the lead concern? Or is that one of those things that used to be a concern in past years but isn't a worry these days?
This unit is basically a therminator but "welded" with brass instead of copper, the brass would be my only worry otherwise I would say that they are a brilliant alternative.

79 Euros Vlad, comes to roughly $140 odd not including postage.

 

[Zwickel]

Hi all,

for the price you may count 1AUS$=0,59

that means ~150.-AUS$

the welding material is 99% copper!

there is a translation fault, it is not brass, it is definitely copper.

you may read the German description, there is written:

Material: 304(Standard:JISG4305-1999)

Anzahl: 20

Lot: 99% Kupfer


Lot means welding material.


anyway, I thought, you may get it in Australia as well, there are plenty of solar systems too.

No, never.

After whirlpooling the wort flows through the chiller by gravity within 20min.
Im using a 3/8" silicon tube.
With or without the chiller it takes 20min.
That means the resistance of the chiller is very low.

Cheers

Hi Chippy,

my holiday is already over, unfortunately.
I have been in Downunder from 22.Feb til 6.Apr.

here some impressions I collected:

nice looking bit of kit zwickel!!!

just my opinion but the lead thing doesnt bother me to much. chances are, especially for the older guys here, you have been exposed to a hell of a lot more lead in your lifetime then you will be exposed to through lead in the solder. also most of the water pipes that are in your house are most likley welded with solder that contains solder. each to there own though.

cheers

thank you Bobby for your comment

anyway, I cant see any lead on that chiller.

the chiller is also used in food industrie as well as in pharmaceutical industrie.

I dont want to force anyone to use such a kind of chiller, just wanna show, there a many alternatives around you.

Im that kind of man who always considers things around to use for brewing beer or not

Cheers

Tops stuff Zwickel, well worth a look over here, as you say we have heaps of solar hot water systems, not sure if they have those heat exchangers though but now I will keep an eye out for them.

Nice photos too!

I stand corrected on the brass issue, it is in fact translated incorrectly as Zwickel has said.
Awesome chiller I reckon, wonder how much they could be landed in Aus for...might have to email the seller......good info zwickel. Loved that pic from Glendambo by the way....but I reckon that there are twice as many flies.....

 

[Zwickel]

how much they could be landed in Aus for...might have to email the seller......

I want to remark that the chiller is made in Korea.
That means, it is not produced for the European market only, I think one can buy it worldwide.

Furthermore I wanna point out, that Germans are worldchampions in tax paying!!!

That means, any product from outside Europe we add 6% customs and 16% GST

Australia is much kindlier to their people

Even the German cars are much cheaper in Australia then here in Germany, makes sense, doesnt it?

After all, I think, the chiller must be much cheaper in Australia then here.

Loved that pic from Glendambo by the way....but I reckon that there are twice as many flies.....

Yes, your absolutely right, Ive never seen that naughty flies here in Europe, aweful, absolutely aweful.

Cheers

Hey Zwickel, any chance of the Korean makers name, they might already sell in Australia.

If you do a search for brazed plate heat exchanger in Australia it will come up with heaps of suppliers. They all look like they would do the trick. No idea on price. Maybe someone like Brissybrew can get these priced up and supply us some along side his thermometers

We must be on same wavelength JJ - I already dropped a line to a few Aussie manufacturers this morning...

Cheers Ross

 

[jimmyjack]

They're also used everywhere in water cooled A/C plants.

Alfa Lavall is another brand.

Could this be the early start to another "BULK BUY" :blink:
Along with http://donaldchrzan.com/index.html Might be nearly enough to send me down that dark path towards AG :huh:

Gday mates,

yes, here it is:

http://www.heattransfer.com.au/index.html

klick on the upper row at the third pic from right:

Brazed plate heat exchangers (BHE) consist of pressed stainless steel plates which are brazed with copper in a vacuum.

For brazing, every alternate plate is rotated by one hundred and eighty degrees to produce two separate flow paths in which the two media flow in opposite directions. The plate contours generate high turbulence during fluid flow, which promotes efficient heat exchange even at low flow rates.

Thats exactly the same heatexchanger.

Cheers
