Hi there. The older belt-drives have more cooling power than modern units. This particular M5-2 runs about 15% of the time. The float-controlled refrigerant systems are extremely efficient from a thermodynamic standpoint. This is a 1/4 HP system cooling an apartment size cabinet, as well. A 1/4 HP compressor in today's world would be adequate for a very high-end side by side full size fridge. This one is about 1/3 the size of that. So it has a very low duty cycle.

@@davida1hiwaaynet Alright, good to know.

Eric, I did one from a 30's domestic fridge. It has the same compressor design, but used sulphur dioxide. Here I test it and take it apart. ua-cam.com/video/2IgdEauioYw/v-deo.html

Thanks!

Hi there. I would hesitate to use these for longterm storage of air since they have no protection from corrosion inside. Reuse for dry reclaimed refrigerant, or every now and then for a portable air tank seems safe to me; but your mileage could vary. As far as adapting to an air system, the port on these tanks is 1/4" SAE Flare. You would need a 1/4" SAE flare female adapter to get to whatever size your system used.

@@davida1hiwaaynet awesome, not long term

Thank you!

Thank you! It was originally a sulphur dioxide system. I have adjusted it and charged it with R152A which is the same thing in Dust-Off cans.

Hi Steve. There is a link to a PDF schematic located in the description of the final part of this video series. I don't see your e-mail address shown on your channel or I would e-mail you.

Almost immediately. Shipped same day.

thanks I just chatted with Jonathan from case parts and hes helping me out. I mentioned your video and he is headed to watch it soon-he was great and was really happy about the recommendation from you. im doing a 50s westy as well. thanks again-great job

Thank you! It is old tech, but built by true craftsmen.

@@davida1hiwaaynet "True Craftsman" = 159 & 51 but both reduce to the # 6 numero de Chico also Michael is a Sies for ya.

Thank you! I have a full rebuild video series on this fridge on my channel, if you haven't seen it already. The description of each video contains the link to the next part, by the way. ua-cam.com/video/LdFclxIDY5k/v-deo.html

Yep, it is. Was originally SO2.

Thanks for the comment! I expect your parents acquaintance had a W-series Frigidaire. That was the next version after this. Here is part 1 of a video series about one of these. ua-cam.com/video/WLXaGD28y7w/v-deo.html

@@davida1hiwaaynet Already took a short peek and I'm sure that is the one ! Thanks !

It would try for sure! The insulation in this cabinet is new and pretty thick compared to some modern fridges. That is one of the biggest keys to efficiency on these. Good insulation is very important.

Yep - no WiFi needed for this one. Just plug it in and let it go!

Thanks for the comment! You are correct about the devolution of quality in the more recent years. It is pervasive and sickening. The belt-drive machines were never maintenance-free and require upkeep and overhaul throughout their lives. That is where they fall short in today's world. The next generation after the belt-drive ere were more or less maintenance free, yet still had a multi-decade design life. That era is pretty well the pinnacle of refrigeration in my opinion. I can't count how many 80 year old GE Monitor Top fridges which still work after only minor repairs to deteriorated wiring. I have heard about vacuum panel insulation and certainly need to investigate that form of insulation. The M5-2 has extruded polystyrene foam board insulation which is pretty good, but nothing like vacuum panels. At this time I have not found a supplier willing to work with me on the vacuum panels.

I understand! That is a thing of beauty for sure. I remember those movers struggling to move it into your kitchen that day! Scary how heavy these are!

These were built to last. The belt-drive units were never "zero maintenance" but they generally don't wear out. Glad you enjoyed it!

Diese alten Dinger sind unkaputtbar - bei uns kühlt ein GE Baujahr '46 ... Grüße aus Indonesien😊

@@user-mv7jg3pb3n Läuft der noch auf Schwefeldioxid?

@@electroimpex8897 Bei den Nachkriegsmodellen von GE wurde - Gottseidank - schon R12 statt SO2 verwendet . Aber sehr nett von Ihnen mich daran zu erinnern - Danke ! LG

@electroimpex - glad to hear your vintage fridge is still running well! Happy to know my videos are making it to people in faraway places such as Germany and Indonesia.

General Electric engineered a new compressor and sold it starting in 1945 just after the War. The earlier model was a scotch yoke machine. This one was engineered for SO2. It was designed for non-miscible oil and refrigerant. When Freon-12 was introduced, GE actually did try this refrigerant in the scotch yoke machines. They had noise complaints due to oil dilution, and thus continued using SO2 in the scotch yoke machines until the end of production during the War. The two machines are easy to tell apart. The 1935-1942 scotch yoke machines have a vertical motor shaft axis. The electrical pass-through terminals are on the bottom. The motor suspension springs are inside the pressure vessel. The external size of the pressure vessel is around 300mm. These have paper and cotton motor winding insulation. They are SO2 units. Monitor Top CK and Flat Top CF fridges are examples. The "post-war" 1945 and newer models have a horizontal motor shaft axis. The electrical terminals are mounted on the end of the pressure vessel. The suspension springs are on the outside of the casing, so the whole compressor is floating on springs. The size of the pressure vessel is much smaller than the older models, maybe only 2/3 as large. This model had a different oil pump and oil specification. It also had enameled magnet wire motor winding. It was always used with Freon-12. The Monitor Top FEA model and many later fridges into the 50's used this compressor.

Thank you!

I'm not sure. This was 16 years ago and I was just hanging out with friends at the pulling track.

I am not a fan of any blends. They tend to separate and the differing components leak at different rates. Also going from an HFC like R134A to a hydrocarbon is going to be dicey. Auto A/C R134A systems have rubber parts in them which are designed to resist PAG oil and HFC refrigerants. Using hydrocarbons in them is likely going to result in leaks or swelling of parts.

Hi there. When I got this car somebody had done a halfway R134A conversion. The oil in the system smelled like POE oil and it contained UV dye. I have a feeling it was probably a mixture of POE and mineral oil. There was too much oil in the system, leading me to believe it had a double charge. After I went back with the new compressor everything has PAG oil which seems to be a better lubricant.

@@davida1hiwaaynet So you would use pag oil in a r152 duster system and not Ester oil? Thanks for your relply ps its going into a 92 f250

Thanks you! It is a very neat piece. Still works today like it did when new. :)

Thanks for your comment! There are a few of these still around but there are less every year. I'm glad there are some that still appreciate them.

By the way, thank you for commenting on my channel. I've been enjoying your old refrigeration system videos as well. I don't think they're very many of us left. I hate to say.
