A few questions

[Dr Jacoby]

I'm very close to buying a 20L braumeister but wanted to check a few things first. Am I right in thinking that the coupling for the tap is a female 3/4" BSP thread?

If I was to build a copper immersion chiller, roughly how many metres (or feet) would I need if the chiller was to hug the inside of the boiler?

What's the distance from the centre pole in the boiler to the outer shell? Could you fit a hop filter with a 6" diameter between the two?

Any help would be much appreciated.

With regard the immersion chiller. You probably won't want to hug the inside of the boiler because of the heating element in the bottom.

I wrapped mine around a corny keg and it fits neatly inside the heating element.

The connection for the tap is a 3/4" female connection. Not sure if it's BSP or not but a BSP nipple fits and doesn't leak if you use thread tape.

Not at home right now so can't measure the gap between the centre rod and the vessel wall, but I'm sure that you'll get an answer pretty quickly here.

Cheers

not exactly sure what you mean by 'boiler' and 'outer shell', if you mean the gap between the edge of the center pole to the inner rim of the kettle it's 17.3 cm

I found a great hop filter for the 20 litre BM at what I think is a reasonable price and custom made to fit. $90.00 US

Here it is

Hi Dicko,

The hop filter looks like Chad's one!!
I've been thinking, what is the main advantage of hop filter in comparison with musseline bags? Reusabiliry?

Yes it appears to be the same but I didn't think that Chad was mass producing them and the last I saw he was only making them for the 50 litre model.

Thanks for the link, that's a fantastic design. I'd go for it straight away if it weren't for the fact that I think it would make it difficult to use my heat stick during the boil, especially towards the end when I put the chiller in.

The filter helps to maximise utilisation by giving the hops plenty of space to move around freely. Also, they are very easy to clean and require minimum effort for multiple hop additions.

Cool, thanks

Am I right in thinking that the coupling for the tap is a female 3/4" BSP thread?

I asked this question to Speidel when I was researching for the Braumeister.

Sure you can change the spigot. We are using 3/4 inch Withworth thread which is close to the BSP thread.

So, it's not BSP but Withworth thread. You can use a BSP threaded part, but I recommend using "teflon" to ensure a good fit without leaks.

I'm on the wrong side of the pond (and not a mechanical engineer either!), but doesn't BSP use the Whitworth thread? For US readers, since the flow isn't under pressure, BSW is close enough to NPT to use some Teflon tape to couple.

Some light reading for you if you're keen.

BSP has the same 55 degree angle as a Whitworth thread...................

You're right. I meant to say NPT, but with all those acronyms I got confused.

Between the pipe and electrical acronyms, it's many trips to Wikipedia

Or a few years in Engineering...
There is a nice reading on NPT (National Pipe Taper) vs. BSP(T) (British Standard Pipe Taper) and their compatibility.
In a nutshell BSPT is compatible with NPT for 1/2" and 3/4" threads which is our case...
