The RAPT Spunding valve is really quite close. All the injection molds for this product are finished and we were about to start manufacturing but we found a slightly more accurate pressure transducer that also was easier to assembly in the housing and we decided to change this but that required tweaks to the PCB and this has set us back slightly. We think this Digital Regulator and Spunding Valve will be available for sale in Australia in March this year. Sorry about the delay. The good news is that the accuracy will be about +/- 1% of the gauge range so its quite accurate compared with other options.

The SS FermZilla is probably also March too as we have found some other ways to make the design more efficient to produce and also reduce the RRP on this too.

Great, thank you so much for the update! Really excited for these!
 
when's the rapt digital spunding valve going to be in stock? i've been waiting for ages!
 
I have a 65watt magnetic pump which screams when running. I’m thinking it’s has bearing/s that are stuffed
Can these be replaced?
 
@KegLand-com-au the KCl pH meter storage solution containers are pretty flimsy. I get a lot of crystallsation (have gone through about 3-4 of these in a couple of years). Is this OK or once they crystallise do we need to discard and get fresh solution? Part number is KL04183
 
Brewzilla gen 4 Equipment Profile ...false bottom
I have seen the value 0.7 gll of false bottom for the BZ gen 4 35 lt profile , but with the central hole all the brewing liquid is drained into the fermenter , then this value would have to be 0 gl ...
Yes or no ?

It's unlikely to be the bearings. I would first take it apart and give it a good clean.

If you remove the impeller and turn the pump on and if the sound stops than this confirms it's not the bearings. I have never seen bearings go on this model before.

Assuming it's not the bearings and you have already given the pump a good clean then I would then replace the impeller unit:

Yes I would agree with that. This product is under review at the moment. We are looking to chage to a tighter sealing container that is also larger in size.

Even with a bit of crystalisation it's still fine to use the solution. The main thing is to make sure the tip is moist as a dried out tip will cause the probe head to degrade very fast.

Mash tun deadspace? I have mine set at 3.5 lts (I measured this)
Trub/chiller loss? I set to 2.75 lts but that can vary with the amount of hops.
 
'm a craft brewer in Brazil. I have a Brewzilla 35 lt gen 4. Checking the pot profile in BrewFather version 2, the dead space value is 0
Should I consider this value? ...due to the central hole ?

G40 Corrosion in thermocouple plug

I've used my G40 for about 3 months continuously now but then I noticed that by temperature readings were jumping around. On close inspection the reason was clear, the terminal contacts had corroded.

It is because condensation is occurring inside the housing, and probably expected given I am setting my cold bath at -4C, fermenting at 11C and cold crashing at 3C in a humid environment. It is clearly causing corrosion over time. You can see from the photo how nasty it is, and I've tried cleaning to no avail.

IMHO this is a serious design fault. The probe contacts should not be exposed to water at all, yet the thermocouple plug and receptacle are right above the cold flow lines. Condensation in there will be inevitable.

Its lucky I am not using all 4 pumps (I am using 2 only), so I've switched to a spare for now. The only solution I see is to regularly change out the probe and the receptor.

Kegland, I'd be grateful for a solution, soon I will run out of receptacles for the thermocouple. I did think about sealing with silicone once the probe was plugged in, but would be concerned I could just make it worse if humid air can ingress from elsewhere.
