My experience,


My experience,

Run into one of these Trane gurus??, 15 years working as a mechanic.

Installed an after market soft start upside down, (cheaper for the company he was employed with), every config. wrong inside delta, bla ,bla etc.

Went in got the chiller running, hasn't faulted on aux, bla .bla yet, been running for three years.

Obviously he didn't get the tick off list to install after market switchgear from TRANE, NOW THATS WHAT I CALL A MONKEY????

This maybe correct , but can the monkey do it right and make it work properly ? JMHO

Getting chillers to do what it was designed to do is simple. Most chillers are reprogrammed to suit the problems of the site or incorrectly selected through inexperienced salesman.

A few split pins, dowelling, one seal tight, the rest so wide ???.

Why don't we make some easy money, and get the chw plant doing what it should be.

Any monkey can rebuild a chiller , takes a smarter monkey to do both.

Sometimes he looks like one too!!! But I do not employ them for their looks???

That's a mighty smart monkey you have.......

Like I preach down under.........a monkey can rebuild a chiller........it takes a technician to find the cause of the failure. My team and I are not doing this as a job but a passion. To be a true technician you need to be able to think outside of the box.
For example, can you set up the clearances between the impeller and the volute without knowing the actual clearance.It is simple, what does the impeller do from the minute the oil pump starts until it reaches maximum capacity? Think!
When I started doing chillers 30 years ago down under the French did not communicate with other countries and you stripped and rebuilt chillers without manuals, without knowing the weights etc. It was challenging, exciting, rewarding and standing back looking at a machine that is running and performing perfectly is a very rewarding feeling.
Just finished rebuilding 3 x 27 year old r22 high speed centrifugal chillers. Should have been scrapped years ago but the bandages are holding. No one else in the state will touch them.
Old but a challenge.

Agreed, I'll even take it step further and dowel the casings. Especially if your going to disassemble it on the ground.

GEEZZ boys was just having a bit of a joke, was fully aware trane make gear driven, have worked on a few, however I always like to throw the trane vs york thing in.

you get 2 feet!?!? sometimes 2 feet seems like a mile in some places.

oops!!!!!!!!!

i did not.
I did make one to hold the York scroll!
I have a bunch of 1000tr YK's.
not my design, I stole it from Entech in Garland Texas!

Like I said, most of the time. Not every room has a forklift or the clearance. I would bet that this is the only one like this that you work on. Now lets compare the real machine rooms, with two feet over head and six feet between the chiller next to it. Then lets see you love on that big girl. Try a gear machine once, you'll like it.

It also takes alot longer to rebuild. I can rebuild a York and a Carrier in 2 days, compared to at least 3 to 4 days for a Trane. Thats only if you have room overhead; get ready for a marathon in low clearance situations. ( I am just speaking of the compressor rebuild part) Lets not even talk about if you lose a motor. Replace just the motor on the York and Carrier, pull the entire compressor for the Trane. Remember, Its hard to stop a Trane; unless you send it cold condenser water, then it will derail on oil loss!

Looks like a copy of the D series. I thought that China was the only ones to reverse engineer. Just kidding.
