they buy them here for $300 ton 15 cents pound vs 24 cents for electric motors
Sealed Units/Compressors (Drained) $300
Electric Motors $480
due to the lost weight id be losing money by processing them

Jg, I pay .15 a pound for them and make money. What numbers are you using?
It would take 34 minutes to just find my tools, another 30 or so to rest after lifting the thing to cut, and more than likely another hour to get the kid down the road to pull the copper from the core for me. But your pictures are worth a thousand words to me in showing me how to do the job the right way. Thanks
Freon Joe;
Thanks for the tutorial. Pics truly are worth a thousand words. I would like to ask you a couple of questions....
How do you recover the Freon?
Do you use the same saw and cutoff wheel to crack open the cases as you do for cutting off the copper?
I have hundreds of pounds of transformers laying around, and have been trying to decide if I could cut the copper off with a chopsaw and then poke the rest through. you have given me some great ideas!!!
I use a metal blade on an old 10" miter saw, and a cutoff wheel on a 4" grinder. The smaller wheels are also much thinner, the big wheels leave quite a kerf, but anything that gets the job done(when it gets done haha ) works for me ; )Quote:

I drain the oil before cutting. The few that have caught fire were from the inside wire harness. Blow 'em out like a candle and move on to the next.Quote:

I get closer to 20 cents so definitely selling as is.Quote:

CFoote, I use Apion recovery pumps for the refrigeranf and a plasma cutter to cut open the compressors. If I could ever figure out how to a vidieo, I would make one showing the whole process.
Well, your pics there do a pretty fine job as it is...I appreciate your willingness to share!!!
lol that would have took me about 4 hours..... .

i want to get the steel block out that has the copper woven through it
any ideas?
haha, i actually asked that question before Sky did, but several of us was wondering. I saw the answer just a few days ago on a miter saw schematic. The "line in" wires are the power in, and the "field" wire goes to the motor, leaving me to suppose it's referring to the wires in the motor, i.e. magnetic/eletrical "field" wires ; )Quote:

I think it's to do with any of those "fields" Joe, (electric,magnetic) motors, CRT monitors, generators, etc, any of the ones that's wound and varnished, they're all in one of those "fields"Quote:

My yard gives a price for "sealed units" which includes not only fridge compressors, but microwave capacitors; basically whatever has oil in it. but, if you've got such a system in place, it prolly behooves you to dismantle them.
I've been formulating how to scrap sealed units for the past year. And now that I have a system I find that it's already in use! But It's reassuring to see my numbers are close to yours!

Thank you freonjoe. Thats me with the compressor quetion and i do believe you are who schooled me on this a couple years ago.i do appreciate you. I would love to come meet you and get a crash course.
Mrbrown, you're welcome to come down anytime. Mark (Idaho Scrapper) and I will show you how we process compressors.
I bought a angle grinder and cut my first compressor in half the other day. The bottom half is still stuck on after some hammer pounding . That's where the copper is so I need to get that half of the shell off. Compressor scrapping is a learned skill obviously I need to get Better lol
Finally got to the wire in the huge compressor I've been working on for a week with my hammer and Angle grinder. The wire is copper colored aluminum Inside Fml. Last time i waste hours on these things . They are going in the steel pile. Waste of time cutting them open in my first impression opinion. I've passed 6 compressors lately and didn't even want them lol. But I'm new to the scrap game.
Good information. The big compressor I just finished working on kicked my butt. As of right now I don't plan on cutting them open anymore lots of hard work and my wire ended up being allimunim. 😡
The bigger compressors, from Invertor heatpumps and maybe larger AC units, for me anyway, tend to be Aluminium or Ali/Copper windings, even then,they don't tend to have much more NonFerrous metal in them, and tend to take about twice or thrice the amount of work.
I sell them as 'Compressors' and save up time instead of wasting it.
Normal fridge and freezer compressors is where my $$ is. Same compressor as a window AC unit, shops drinks cooler (and find to be true) I expect.
Thanks for the use of the word " thrice". Don't get to hear it used outside of a few old movies. 73, Mike
That's why I made a cheat sheet on which compressors have aluminum windings!
Any of you tried a metal cutting circular saw on these?
Joe
do you drain them sum*****es first or do you cut them with oil inside?
It looks like you have a bucket under the table saw, is that for the oil when it spills?
Martin
Hi Martin,
We cut them up with the oil in them. After the winding core is pulled, we dump out the oil in a bucket under the cutting table. The pan under the saw is to catch copper dust.
I am confused .... don't you spill oil all over the place that way?
Freonjoe,
Just wanted to thank you for all the knowledge and information that you have freely given to the forum over the years. Your strategies and techniques have proven to be valuable in other scrapping endeavors as well. Thanks.
Thank you Patriot! Martin, I'm not sure what you mean by spill oil all over. There is a pan under the cutting table and the compressor doesn't get moved from the time that you set it on the table until after the winding core is removed.
I was under the impression that you put the compressor on the side when you cut it on the cutting table just moving it around as you go along the seam does that not make this oil spill out as soon as you have it cut going?
We cut them up while they are upright. With a plasma cutter, it is easy to run all the way around the shell without ever moving the compressor.
I might just need to plan a road trip to Idaho. Lol. Would love to see your setup and operation.
Anytime Aph! If scrapdaddyj and idaho scrapper weren't so lazy, we would post a video on cutting them.
I might have to borrow that list. Didn't have any aluminum on the last batch but had a few aluminum/copper. Don't remember what they were out of but it's the first time I've come across them.Quote:
