Large orange can...or tan?

[AiResearch]

Did Trane really make a 50 ton 6 cyl hermetic reciprocating r22 compressor?

Have seen some large bristols and lennox with king valves and unloaders.

And some 15 horse Trane's.

But never a 50.

Kinda like that 69 427 camaro running around town everyone is talking about , yet you never see.

And if so , was it a GE? (guess)

The size of a 30 gal rubbermaid? (guess)

[Dallas Duster]

I have only seen a 30 ton myself.

[AiResearch]

That is still massive.

Any details?

Looks like a big pot compressor with unloader solenoid coils down by the pecker head .

[AiResearch]

Alright. Im guessing it was a rooftop unit compressor.

Thanks for the reply~

Yes and pretty sure it was tan in color.

Forget the tin cans....... Did someone mention a Copo:cheers:

:grin2: central office production order? :grin2:

Ya cans no fun!!!!

I think its a 30 or 40ton, Its been a while. We changed a couple out a few years ago, but its been 2 years since I have seen one.

I do remember that its one big ass tin can.

:grin2: Copeland has a 40 horse scroll now. (not tandem)

[y7turbo]

See the attached file. look on page 77.

almost 30 inches tall and just over 18 inches in diameter for the 30ton.

Thats a heavy ass boat anchor :grin2:

[y7turbo]

I think I remember my boss saying that the big ass trane tin can could be rebuilt, I wonder if the copeland is the same.

Ill have to ask him monday.

I have seen some large tin can recips in old self-contained SWUA or maybe they were SWUB units, but all the Intellipaks I have worked on that were old enough to have recips in them had R and M compressors.

[AiResearch]

Thanks for the replies you guys~

Turbo , have not had a chance to check out your pdf yet but ill get back to you. I searched for a while to try and find info on these compressors but no luck , so big ups to you! Your dimensions really put an idea in my head. And yea I have heard of rebuilders opening the shell for overhaul and re-welding. Dont know about a large scroll though. LOL boat anchor is right! If I had to guess I would say the large Trane hermetic had six cylinders , three heads arranged like an 06D Carlyle. Bristol had a 25 ton 6 cylinder recip radial!!!! Some of these large hermetics had suction and discharge king valves , 2 external unloader solenoids , aux connections for various electrical safety's , and an angle valve for oil access at the bottom.

Rob , me 2 on the intellipacks had semi's in them. Then they switched from 4 or 2 big-blocks to like 8 or more 3d's! Wild... When you say self contained where you saw the large hermetic...do you mean a large capacity indoor water cooled?? Thats what I think of for self contained. Although an outdoor package unit is self contained also. Just trying to get an idea of what equip Trane was using this large hermetic in.

One more thing.. If that big ass Trane can was tan in color.. And from the early 80's... There's a good change it was a GE compressor. Which , IMO , was THE finest hermetic line ever manufactured. Have seen killer endurance and performance from GE air conditioning. Never saw a failure , or even heard of one.

Thanks a million bud. Of all my Trane literature I do not have this one. Fantastic. The model K. Interesting. A centrifugal oil pump? Not a positive displacement type. WoW. Internal accumulator , thats pretty common. Reversible rotation , kool. Oil sightglass and charging valve , awesome. Three capacity stages. The picture shows 4 cylinders in a vee. There must be another head around the corner. Over 500 pounds. Ring valves with springs in leu of reeds. Trane semi-hermetic style. Wonder if it has the safety anti slugging head as well. Where the whole discharge valve can lift under heavy springs should a non-compressible enter the cylinder. Low and high pressure control taps. Also , 4 pole motor for 1750 vs the normal 3450 on 2 pole for hermetic. Look at the rated capacity for condensing temp. 130* , that is the hottest day! Assuming a 30* TD on condenser coil that is 100* ambient. On a cooler day day with still a load on the evaporator , compression ratio would go down and she may do more capacity! Thirty tons it is , not 50. And there you have it. I owe you a sixer of Turbo Dog!~

Something like this on a good air conditioner with great maitenance and a high performance air side ..... with the proper electrical protection ..... should last a LONG time!

Lookin forward to it.

Lookin forward to it.

I suppose a product could be shipped to you :grin2:

Yes; large indoor package units 20-80 ton range, with flooded water cooled condensers and DX refrigerant to air evaporators. The compressors were tan as I recall... It's been a long time since I've seen one and I've seen many more of those with R and M compressors. I think the SWUAs were the ones with the semis in them. They were VAV units with the old Honeywell step controllers and ceramic cams or a NSB

Good information Rob. Thanks for the reply. I like those indoor self contained jobs. They make great units I think for somewhat high rise office buildings. Ya the honeywell step controller I remember those! The SWUA okay with R model semi. Good stuff right there. Carrier makes a kick butt self contained also. Built like a Mack truck!

I had a 120 ton Trane chiller under contract. It had two tan recip compressors. One tag said "Service First" the other said "brainerd". One tore up and the other circuit flooded. I pulled out the bad compressor with a motor lift. I moved the good compressor to the good circuit. It ran that way several months while they played the bidding game for a new chiller. Two weeks before we changed out the old beast the middle belt driven fan tore up. I put a tarp over the fan hole and across condenser of the down circuit side. That good circuit ran better than I ever seen it before. I put the old tan recip in the back of an S10. It felt rather dangerous driving that much weight to a rebuild shop that probably gave my supervisor $50.00.

[y7turbo]

the other said "brainerd". .

Brainerd is a compressor remanufacturing company, we use a lot of their compressors.

Now that I reread, mine was semi-hermetic.

[AiResearch]

One of my text books states there were companies overhauling these large cans. Cut n weld. Sure would be a shame to scrap a unique piece like that.

I edited my post. I didnt catch that your unit was 120 ton , I guess I missed that part.

Im almost 100% sure Brainerd does rebuild the big trane tin cans..

[AiResearch]

Recips disappearing in air conditioning. They will be missed. Energy hogs they are. Too much internal friction and moving parts.

Supermarket refrig will use them for a while yet b/c they have high compression ratio requirements.

Scroll cant hang there.

Or screw for that matter.

They would have to go multi-stage to use those compression devices.

For low temp anyway.

[mrhvacmechanic]

They are "K" compressors. They are very loud but are great. Serviced many a rooftop units with them.

Too bad they use scrolls now.

:yes:

[mrhvacmechanic]

One other mention here, the K's had unloaders also.
