Love that Star Delta startup sounds, big boys toys.

Sweet music. Love the low pressure machines.

I remember working on a couple of those in the mid eighties in Gatwick Airport UK . Solid machine..

Used to work on centrifugals to 2000 ton. Its all fun and games until tear down comes along lol

We had to rob parts from this chiller to get 1 & 3 running when I started this building back up after 10+ years off being more or less mothballed.

One of things I always check is to make sure the pump-out pump is actually working and pulling into a good vacuum.

12:38 That sounded awesom

Like your vedios very detailed hopefully someday I can learn and work on chillers and so forth I'm learning alot from your vedios keep up the good work.

Like to see more videos like this

Love the Trane Centravacs chillers whether it’s the older R11 units or the mordern 1233ZD units.

Good job and amazing

I’ve found a lot of the buzzing on those style contractors comes from the upper armature clips that have came loose

Beautiful chiller

Sounds smooth

Nice video. I'm new in the world of chillers and yours videos are very helpful and interresting, I try to listen all of Them. Keep it Up 🤘 Btw listening you from Montreal , Canada.

Hey I know next to nothing about these Trane units , could you make a vid explaining what this purger is about and what it does , that would be awesome. I've never seen such a device , I'd love to know more about it . Thanks a lot man , really glad I found your channel 👍

The building engineer should be next to you as your working. Thanks again for the videos! 🍺🍺🍺🥃🥃🏌🏻‍♀️🎯 Stay safe. Retired (werk'n)keyboard super tech. Wear your safety glasses!

Yea might be some good money for a changeout

The cause of the pressure difference is many factors, you have to check it one by one

Kalau valve ekspansi masih bagus dan tekanan air normal coba vacum ulang sampai standar micron pastikan tidak bocor dan ganti freon dan oli

I never understood why the dehydrator makes a trap for the liquid drain back. Wouldn’t you want it to Coke out of the drier and go straight to the condenser?

Drain line on purge unit should have 2 inches of slope per foot, why would it go vertical after the dryer? Curio

I dont get to work on centrifugal's...only a few times. I really want to learn more about them. I mostly work on process chillers or air cooled. I understand how these low pressure units operate, just not a ton of hands on experience.

The oil case on that older unit looks like a standard oil burner filter set up , is it close to that design ?

What’s your favorite grease to use on all your gearboxes etc etc ?

Can you explain the set points and approach temps like I don't know?

Lol I’m wrong I was like oh yea

Throw a Trane TR200 VFD on that chiller and it will outlast that York. Lol Jk York YK’s a good machine.

can surge be prevented by using hot gas bypass?

Yea change that drier

Bandage and bandage eventually they say ok
