Hi everyone,
I figured I'd share my process for my first electric brewing setup. I know a lot of you have 50L + setups but I wanted to share my little 30L (max volume) kettle for those who are just starting out or have little space.
So, first off I'll list all the parts and their cost and then go onto the build.
Parts:
All costs in NZ $, excluding shipping
Berma Rex c100 PID temperature controller with K-type thermocouple and 40amp solid state relay - $67
Camco 2500W 240V Ultra Low Watt Density (though it looks a little short for ulwd) - $27
3 x 20amp toggle switches - $18
Cable sourced off old high rated appliances - $0
316 Stainless hardware: 1/2" 3-piece ball valve, 1/2" weld nipple, 1/2" hose tail, 1" npt coupling - $60
30L, 202 stainless kettle 1mm wall & base thickness - $50 (it's a bit ****, but will do the job)
Odd bit's like the boxes, heat sink, and ring connectors - $20
All in all, probably around $270 if you include shipping.
I removed the mechanical relay from the Rex c100 and simply soldered some wires across to complete the new output for 10ish vdc (heaps of good info on how to do this around the place).
Other than that, it was a fairly straightforward process and I just had to make sure I was clear in my intention and therefore diagram, and then patient in the testing phase which seems fine at this stage.
The three switches are:
Left - PID on/off which also activates the PID side of the relay.
Middle - On/off for the element through the PID controlled relay.
Right - On/off full power to the element (not requiring any other switch to be on).
I swappd out the main power cord though as it got a little too warm for my liking during the 5min test. Oh, and also add some kind of plug to connect between the element cord and the PID control box (some kind of XLR type thing if I can find one rated for the 10ish amps at 240vac I need). Then I should be able to plug this thing in between my brew kettle and my temp controlled fermentor box - saving a whole new PID.
Cheers everyone, I've been lurking on here for a while so thanks for the great community and knowledge.
