Freezers?

For anyone interested, the best freezer i found on amazon is this: https://a.co/d/8hQaU3N
Even though the title says it only goes to -4 it looks like its wrong, if you go down to the description it states it will go down to -40c. It also is available from this walmart link: https://www.walmart.com/ip/Northair...r-Chest-14-to-40/1314859596?classType=VARIANT , even though its a different "brand" its the same thing. I ended up just purchasing a ult25neu lab freezer that goes to -86c for 700 bucks shipped on ebay, so if you want to spend a little more then ebay is a good place to look
The ult25neu is a very cool, freezer! Most of the prices I am seeing on eBay are over $1k, did you offer $700 to the seller that has a bunch of them? I bought a $200 1.1 cuft freezer that gets down to -22 but the one you found is MUCH better.

This was an auction that was listed for 500 dollars plus 150 dollar shipping charge, i bid on it on the last 30 seconds left and got it. After taxes and all it ended up being 700 bucks. If you are going to buy one just triple check that they say its in good working order, there are a lot of vendors that say their freezer only goes up to -70c which is most likely saying that their freezer is probably on the way out, according to sterling a ult25neu should go from 25c to -86c empty in around 4 hours, i low balled the hell out of this seller: https://www.ebay.com/itm/1867097121...Dumg4pfTU2&var=&widget_ver=artemis&media=COPY
He sent me an offer for 600 dollars, but if you see the post it says -70c so when i asked him about it he says he had it on for over 12 hours and would not go below -70c so i declined purchasing it. Try to low ball the ones that are good condition, they typically do not see a big volume of sales so they are going to be more willing to get rid of them for a lower price.
 
One thing to know about ULT25NEU is that it is not quiet. It sounds like a window AC unit. I have an equipment utility room where I keep mine, so I don't hear it, but you probably don't want that thing in your bedroom.

Good to know, ill probably keep it in another room, as far as reliability how has your unit held up?
 
Mine was manufactured in early 2021, but I've only had it for a month, so it safe to assume it hasn't broken down in 3 years. I think as long as you clean the filter monthly, there is not much to break there. I have mine on a UPS to avoid power surges and outages.

Thanks for the additional info an guidance.
 
Has anyone purchased that northair chest freezer from the Amazon link? Seems like a good deal if it maintains temperature and isn’t overly noisy
 
I have had this as my peptide freezer for a few years and can't recommend it more highly: Amazon link

It is a small manual defrost freezer, so no auto defrost mode causing temp fluctuations. I keep a bluetooth temp monitor in there so know it stays a consistent -23c. Honeywell is a legit brand.
 
The northair and adt look exactly the same, they must have the same OEM. Can you see who manufactured it?
 
Let me know if you can figure out who OEM's these specific 3.5 cu/ft freezer. Surely they can't be the only ones making one that gets to -40 that affordable.

Edit: This one specifically. https://www.amazon.com/ADT-Freezer-Free-Standing-Freezers-CBlack/dp/B0BFDTG4NQ
I did end up finding it but I couldn't locate anything quite similar that was as cost effective.


There are these two but I can't find a cheap rebrand anywhere.


 
Anyone thought about hacking their own fridge with an aftermarket thermostat? Tons of guides on YouTube from the homebrew community. Would love to see how cold it can get if someone takes on the project.

I have but you start running into limitations with the type of refrigerant used and amount of insulation. I had a chest freezer that I let run 24/7 for 5 days and It was only able to get down to -20 F unfortunately. It's pretty hard to get colder without other design considerations.
 
I have that freezer and I keep a temp sensor in it. I've only had it a month but it's rock solid -30c -40c constantly. I'm happy with it.

What sensor/monitor are y'all using? I'd like to get one for my freezer but have no idea what's actually good.
 
For about an additional $100 we could get the kind of freezers designed to store vaccines from Alibaba, we just need someone to arrange a group buy. My preferred option tbh.
You know, I was thinking about this the other night but I don't know how many would genuinely be interested.


That's the cheapest one that I found so far but haven't looked into what it would cost to ship over here.

DW-86W25 seems to be the OEM model number for all of these little -86c freezers.

You can find the branded version of these used on eBay. Another user reported buying one for $750 shipped but the best price I see today is $1040 w/free shipping. They have >10 units available so you might be able to make an offer. Just search ebay for ULT25NEU. I like the fact that it will run off of 12vdc if there is a power failure. Something to consider, I read that they are LOUD so you might need a dedicated space for it.

I was looking at this one which is a little cheaper (if you buy bulk).

This one doesn't get as cold and looks like it is 12V DC only, so you would need to add a converter. Not trying to poo-poo your find, just pointing out what.I saw when I reviewed the OEM's website.

I am using a 1.1cu ft $200 amazon special. It is small, quiet and holds <20C; actually today it varied from -22.3C to -22.6C which is what I typically see if I don't open it to add/remove peps. I am fine with this temp for storage and will re-test my peps next October to see how they are holding up.
