Major Chiller Leak Repairs On Screw Compressor Trane Air Cooled Chiller

We had some major leak repairs on a air cooled chiller RTAA Trane chiller. We broke open a screw compressor to replace the rotor housing to bearing housing oring. Sadly we had a very close call on the compressor at startup but it worked out.

I need to work with experienced people like you that pay attention that have that intelligence enough to hold all that information in your head I love picking brains like that that's why I'm a service person because it makes me use my brain thanks for what you do thank you for the videos it really does help.

[@HVACTIME]

Enjoy doing it, I offer tech support and personal training through my website if ever interested.

[@user-qg8xu6xe2j]

I love watching your videos. You break everything down into simple terms.. I have learned a lot of common terminology of chillers. Keep posting the videos and I'll keep watching

[@RJ-ix4co]

Sounds like you have the same luck I have with our Trane distributor here in Okc. Some of my buildings have some RTAA’s and have had so many issues getting the correct parts…. Constantly. So much so that when they say 3 days for a part I just go ahead and plan for 10 days because I know it most likely will 1. Not arrive on time and 2. It will be the wrong part. I feel your pain so much on this video.

[@derrickenbuenosaires]

These compressors are a lot more durable than what we give them credit for. It wasn't an ideal situation what happened here but shit happens. I had chiller with a 20hp 4D discus sit out for almost a year with no discharge service valve since the valve failed and could not be sourced within the country. I transferred the original part to the customer so that he can get it machined and made at a custom shop. I strapped the discharge up like you did here with electrical tape, a plastic bag over it and more tape. The customer sat on his ass with the part until summer arrived basically. I forced an oil change on him and more $$ added to the quote no questions asked. I would've loved to work with a guy like you back in the states. The equipment you work on and the challenges is my kind of gig.

[@patrickvafbhvac5248]

Great job. I have experienced one of those heart stopping moments. After a repair like that I always let the crankcase heaters take over for 24hrs. It is amazing how it helps everything lubricated

[@HVACTIME]

Thats a good idea, hard to have that time usually.

[@joshstevens9826]

I've re sealed the slide valve piston on a ys frick compressor, but have never been that far into a trane screw. Very cool. Thanks for the video

[@acechoice45]

I worked on a lot of scroll and centrifugal chillers. This video was very helpful regarding screw compressors thanks!

[@robertwheeler8476]

I worked for Trane and we got the wrong parts all the time. In the end, rather than just using the model number and serial, we used to get the model numbers off the compressor or other parts where possible. It is worth noting that the parts department are mostly non technical. They get the details from a database and you hope they press the right keys!!

[@HVACTIME]

Its true, sadly I tried that here and still got same result. They chose to ignore the compressor tags and went for the chiller tag instead.

[@OTHG6v]

Why did everyone “used to work” for Trane…. Me too. 15yrs.

[@shadowbanned69]

Yeah that's a bad feeling when it don't start up...all that work for nothing and now I gotta go back to square 1....ugh 😩 Glad it worked out in the end

[@juanskatebr]

great video! from experience giving technical assistance to Trane and other leading brands, i always developed some kinda of plug/tampons for the connections. Don't need to be the strongest/spiff ones. Just 4/5 stable PSI avoid any air/moisture to enter the circuit. Maybe few houndred bucks for the client but it's always better for both sidesthan taking the risk of having a production line stopped for longer.

[@20antman]

If the liquid valve gives trouble. Use the vapor valve as you did. But flip the tank upside down. It’s actually better than using the liquid valve with a dip tube.

[@HVACTIME]

That would have been good advice

[@bobbyisaac8003]

7:49 Putting a lot of faith into Trane getting the right part and especially when You Pay for overnight, it's Always at least 2-3 days. Yes and now that Trane has changed their parts and sales computer program (once again) They literally have lost so many part numbers and/or how, when,or if they are going to get any item. When you have to go into the warehouse and show the parts person what parts on an old or warranty return compressor that you need, then it turns into a half hour class for all sales people including manager and outside sales of what this part actually is, does and what parts you need so that they understand because they don't know how to look up stuff on their own site.

[@joshuaricks7730]

I work for Trane out of New Orleans and even we get stuff wrong from parts. Most of have good luck with getting everything through Trane 360

[@joshstevens9826]

I've always been taught, by 30 year chiller mechanics, to use dow corning high vacuum grease on all o rings.

[@jman0870]

Nylog didn’t exist when those chiller guys were in their prime

[@gabrielmanut]

Assistindo aqui do Brasil. Pena que aconteceu esse problema, dizemos por aqui: faz parte do jogo. Quero dar os parabéns pelo conteúdo, e se serve de consolo não é muito diferente aqui no Brasil. Nas RTAA's nós pedimos um "R'NEW" substituição completa do compressor, obviamente as chances de retrabalho são menores. Más verdade seria uma oportunidade de ouro realizar esse serviço. Essa experiência não tem preço. Já adianto que vc me inspirou, vou buscar trazer mais conteúdos como esse. E seria muito bom trabalho com um profissional igual a você. Abraço E não esqueça de beber água. Gabriel

[@rsesrochester8391]

Trane and JCI are really good at screwing up parts orders, love it when Trane then tries to charge me re-stoking fees for their mistakes. I don't give them the unit serial number for more than one reason if you know what I mean, I get the parts numbers directly from the comfortsite.

[@20antman]

Dude always put the parts request in writing such as email. I tell them send everything by email. I will call you only to run the credit card. I had jci send me a $2k valve. Sent to me for the wrong circuit. They told me no refund. Wtf? It’s all in the email very clear. They had to eat it,

[@mjalco7410]

Nice job my friend Thank you

[@leslieorm4905]

Great job you guys did

[@rmalanis13]

I noticed that the EXV was left open while charging. Wouldn’t that allow liquid refrigerant to enter suction of compressor? Could have caused binding, the over night let the refrigerant boil off with the CCH.

[@realestateservicessaleshea99]

SUPER-YORK ! 😎 THANKS AGAIN FOR THE VIDEO! 🍺🍺🍺🥃🥃🍿🎯 Stay safe. Retired (werk'n)keyboard super tech. Wear your safety glasses!

[@staceymodisette1149]

model number helps a lot when ordering parts

[@bermyboy7616]

How did you remove the bolt to the shaft that ran through the rotor?

[@sterlingarcher46]

I didn't know Trane US messed up the parts like that , being across the pond that kinda makes me less pissed off 😅 By the way , I thought Nylog would sorta hold the O-ring in place ? Over here we use the Parker Super O-lube , it's sticky so it holds it in place , but I don't like it because its Silicon based so I don't want any of it getting into the circuit ...

[@HVACTIME]

Many times the nylog does hold it but sometimes the oring stretchs some and doesnt fit perfectly.

[@throttlebottle5906]

more water in bucket, overflowing from hose cold water and coils spread apart more.

[@drodriguez394]

If the liquid valve ever goes bad. Flip the recovery cyl… if you guys can move that heavy can. That vapor port will then be liquid.

[@lee-johnson]

You know what happens at the drive-through!

[@atemiebristol1212]

Great Job sir, I'm having a VSD communication failure on my York Air Cooled Chiller, what could be the cause. Thanks, I await your feedback sir.

[@jonnymac31]

Hell yeah

[@creativetradesman6833]

Awesome experience thanks for sharing! I saw the pin in the video that you guys are hiring. Is the company you work for smaller than 100 employees? There’s a chance I could be unemployed here in the near future. Thanks for the videos man I really enjoy your content.

[@HVACTIME]

We are under 100. Send me an email with your resume, let's talk further.

[@darrencolby5689]

Wow you guys still use R22 in the USA.!!!

[@Fryloc87HVAC]

yep! and it's expensive!

[@samuelarcher9236]

Stationary equipment was never the problem, as it can be tightened up and usually was kept that way. You might lose a few pounds of Freon in a decade, at most; and on a Freon-12 system it is even easier to hold because condenser pressure need not be so high. That does not compare with the dozens of pounds of Freon that would be gassed off every shift by a printed circuit fabrication plant. On the most bitterly cold nights, I would see a cloud of re-condensing Freon hanging over a plant in my area. Of course, the transportation air conditioning was a big insult to the ozonosphere, but we proved that could be tightened up, as well. Our atmosphere is making good progress at repairing the damage we were inflicting on it with Freon.

[@JP-sd2cw]

Quick question, Did you drain the water piping before pulling the gas out? If it has glycol in it i assume you dont need to drain it? If not, why, i thought you could freeze the tubes that way.

[@HVACTIME]

Its a DX barrel so it wont freeze like a flooded barrel. I was also flowing water to speed up process

[@JD-rl8bw]

If that happens again put a nitrogen bleed on the compressor to keep air and moisture out. We have went as far as having a liquid nitrogen tank delivered if it was going to be a long delay

[@20antman]

Yea I like that idea of yhe nitro constant purge.

[@irfvnfaedah5776]

Waw ,just using water for cooling refrigerant after recovery pump,

[@Weird_1]

Hey question. The gasket on the discharge side. Did you all end up having to pull that hole assembly and shaft out or did you just stretch the gasket over the discharge house?

[@HVACTIME]

You stretch it, the service manual calls for that too.

[@HVACTIME]

Its terrifying your first couple times because your common sense says this ain't right but it works

[@jerrypeal653]

I hated those Trane SqareD VFD s.

[@HiddenResolve]

For what you normally do, do you use filter driers on the recovery machines ever? In school we had one on every machine.

[@HVACTIME]

Very rarely

[@HiddenResolve]

@@HVACTIME Nobody in my company has one on their machines either, is it just because it slows the recovery down too much to be worth it for the cost of the machine?

[@HVACTIME]

@@HiddenResolve honestly I think its just not a standard practice so its never thought of.

[@HiddenResolve]

@@HVACTIME Ah, yeah I would believe it. I am mostly res/commercial so most of the techs I work with just replace the drier and call it a day. But I never work with chillers so always cool watching your videos, keep up the good work bro!

[@JaromKizhakkanudan]

Anybody can replay me, RTAB trane chiller alaram,circuit shutdown has occurred, how to reset

[@commenter5469]

That thing had moisture and got hot at some point?!

[@HVACTIME]

Moisture was from it sitting waiting on right parts. We deal with extreme heat in the summer so everything is always on the edge of overheating lol.
