- With the new GC2 glycol chiller from Grainfather Stiffo and Rakey take a look at how versatile this little chiller can be when you couple it with the powerfully connected GCA set also from Grainfather! Your options really are limitless with this set up so if you have FV’s you already are keen to get control over or if you are looking at stepping up from a Ferm fridge then take a look!

I hadn’t realised the GC2 was quite so ‘dinky’. It would even work in my kitchen set up. Great video.
Starting out on my home brewing the GRAINFATHER GC2 - Glycol Chiller might be out of my price range. But it’s definitely something I would be expanding on. Also, I like the way you went through connecting this up this will really help people figure out where everything goes. And for me, the best part is that it fits on the 30 little fermenter bucket as I brew small batches. Great video lads.
Great demonstration video. I am a happy user of the GC4 since it was launched. One of my favorite features is the no-drip connections. I am using it with a GF conical and an F40. Compared to what you have shown in the video (for the Brewtools fermenter) I am using the Brewtools no drip connections. Just a small extra cost for the easier cleaning process and moving the unit around while not connected to the chilling lines. The GF or BT connections could be easily adapted to the New malt Miller SS bucket or a plastic bucket as well. I feel like the barb connections do not offer much flexibility
Thanks for the insight! We would suggest adding some for of no drip quick connector too
Will the GC2 work in a cold environment unlike domestic fridges that need to be in a house and not in a cold garage. Nice to see all the options good informative video.
All units that refrigerate don't really like the cold too much, that being said we have a few of the team here with GC4's in their garages and they don't seem to have any issues with them. I think it will depend on the extremes you're placing it mostly, a shed in the middle of winter vs a garage thats attached to your house will be very different
Temperature range? I don't recall seeing any discussion of how low this will go...but I may have missed it.
The GF system will easily go to 5c but we have had some down to 2c, depending on the time of year.
Makes me want to sell my GC 4. Wonder if it’s as efficient and if the noise is more or less. Also energy consumption??
If it’s the same cooling and lagering power and less noisy just two ports I switch 😅
Sound is about the same as the GC4, it's a great little chiller!
How can I remove the water and glycol mix out of the Fermenter or cooling element without losing some water? Is that possible?
I am not 100% sure what you're referring too but you can drain the Glycol water mix from the chiller, there is a drain port at the back. If you want to drain it from the chiller coil then after it's been disconnected you can turn it upside down to drain. Jacketed FV's like the brewtools one you can drain but uncoupling them from the hoses, although most people would want some form of shut off to prevent this and keep the glycol mix inside for the next brew. The Grainfather 30L one has a brass coupling which doesn't allow for draining directly but you can remove the brass fitting if you wanted to drain them. Hope this helps 🍻
Is the glycol tank really big enough to fill that F80 jacket? I can see that needing topped up lol. Looks a really nice dinky glycol.
Generally when you add a second FV to these chillers you will always need to to top up the glycol mixture. The GF30's need about 400-500ml more added so the F80 would likely need about double that, possibly a little more.
Hi guys. Great video. Can you see any issues with connecting the GC2 to a fermzilla gen3? Particularly interested to check that the heat pad would be ok on the thin plastic?
Without testing it on a fermzilla it's hard to say but in theory it would be fine. If you have the chiller coil for the fermzilla to attach the coolant hoses with. The heat pad works on a plastic fermenter bucket perfectly so again I see no reason why this wouldn't work but as with all things bespoke you may want to do some research first 👍🏻
Don't you have that backwards?
You want COLD IN to go at the top and then HOT OUT to go at the bottom. This way the coldest glycol is hitting the hottest liquid first and then moving towards the colder liquid as it warms up. This should provide a more stable and even distribution of temperature.
Hey! Just double checked, Grainfather advise for maximum efficiency to connect the cold in pipe to the bottom inlet.
Hi everyone, does someone know the refrigerant type of liquid used in this device ? R134a, R290 ? Is it able to cold crash one conical fermenter while stabilising another one at 18°C ? (Room temperature about 22°C / 30liters fermenters)
Hey! Not sure on the refrigerant style but it can control 2 FV's at a time, independently of each other 👍🏻
Nice video, thanks! I'm seriously consedering buying this toy. I have just one question. Is it capable to cold crash 2 GF conical fermenters in parallel (with ambient temperature about 22 C) or would you recommend the bigger brother for this purpose?
No problem with that at all! Plus it has £100 off this week!!! www.themaltmiller.co.uk/product/grainfather-gc2-glycol-chiller/
Does the gca heating pad fit on the cone of a miniuni+?
If you had the MiniUni+ hung on the wall, you would be able to attached it more or less but when it's on the stand it might be more tricky. The MiniUni, unjacketed version, it would be fine with but then you have the issue of no cooling option yet
@@themaltmiller8438 when it's on the stand it might be more tricky. Would it be possible or not?
I have two gf30's so on my gc4 I have two slots left for hopefully a miniuni+. But all stands or falls wether the heating pad fits.
Great vid, how could I incorporate this with ftss system? I only need the the glycol side as I use a cool box currently,am I able to connect to the ss brewtech controller?
Not that we are aware of, it's designed to work with the GF control box
@@themaltmiller8438 looks like ss brewtech needed but they’re so expensive
@@kevinwalsh2566 Other option is to replace the FTSs control box with the Grainfather GCA. You then have wireless temp control plug and play. We use it at TMM HQ and its a brilliant set up
Is glycol safe?
It is a hazardous chemical, yes. You need to avoid contact with skin and do not ingest
It is recommended to use food-grade glycol with these chillers.
