I’ve been in the field for 10 years , the last 5 working on chillers air and water cooled comfort cooling and process and boilers. You’re my favorite chiller related channel and really appreciate the time you put into your videos . I have gone through the process of creating and editing a few videos myself , so I know how much time and effort and it takes . Just wanted to say I appreciate the time you put into these while already having a home life and a full time job , all the intention to spread knowledge within our field
pretty neat trick with the sight glass to find the oil level! Thanks for sharing
I have absolutely no clue what yall are taking about but it's pretty interesting.
You a sharp fella!
Those Trane chillers... Always expecting surprise from it. The first time I got touch with one was when I had no idea that there's an oil cooler integrated with condenser 😂 And taking infrared camera for service too, because of this oil separator and compressor having no sight glass 😅
My friend. I bought transparent hoses on Aliexpress 5 years ago. Re-equipped in the hydraulic press. I have a supply of such hoses. With them I go to Chiller. But I still don't understand Trane's designers. In total, you need to cut three or two glasses into the oil separator. RTAA is the best model for me. and the 22nd refrigerant is the best refrigerant for high evaporation temperatures.
Very smart idea with the sight glass on the hoses. I will for sure be using that in the future when in a pinch.
That’s actually in the IOM in the back under the maintenance section.
They mak a nice tall 8 or 10" tall sight glass that's similar with 1/4" flair fittings on it that make it easier to identify the level. I used one once, unfortunately it wasn't mine so I'm typically using the method he shows with the little sight glass.
My teacher used you approach video for school last night lol. Thanks for the knowledge you are passing on.
What school you go to?
It is call AACP. Association of Air Conditions Professionals. It a 4 year program and we were going over chillers and the different type.
Good catch on this tricky one
You’re one smart guy
I worked for Trane and their RTAA - RTAC units. I've found the oil filter to be culprit very often. Oil would be moved out of the compressor into the Cond. Barrel. Replace the the oil filter and dryer and this problem will disappear.
We use transparent hoses and works very well.
Where do you get transparent hoses!!!??
Interesting video!
Cómo quisiera saber hablar inglés para seguir de cerca las clases de este excelente maestro
I’ve worked on this model before. Did the oil level thing. Wish they would have put in two sight glasses, one at the low limit and one at the high. Would be less of a PITA. Did you find out why the level was low, and where the oil went? On the unit we had, one circuit was flat on delivery, and two compressor processor boards were bad.
A few months ago i bought a Hikmicro Pocket2 thermal camera....it is pretty dang nice and has good resolution. I also have the Flir One Pro which is also pretty decent...but i like the Hikmicro over the Flir
The whole temperature difference i didn't quite grasp because I'm not used to this type of oil management, I'm gonna watch again and try and do some research.
Bitzer has an integrated oil separator which seems to work pretty well .
Nice catch. My question is about the oil. There are no oil leaks and things of that nature since you didn’t say it. Do you think the oil is trapped in the evap, it had to go somewhere?
I heard you say you changed the compressor.
Is it weird that I can pick out the CGAM in the background? 😆
Love your videos they are a big help. How can anyone get a hold of you

Please can send link for that side glass?
Sir kindly make a video of how the system pump down the trane chiller RTAC
Where can we get one of those sight glasses on your hoses ?
👍👍👍
Please replay any body. My chiller RTAH211, alaram circuit shutdown has occurred.?
So where did the oil go? Oil loss over the years of checking the level and random repairs?
And a compressor replacement. New compressor was shipped dry but additional oil was never added. Old compressor took a large quantity of oil with it.
@@HVACTIME that’ll do it!
Where did the oil go? Is it traped in the system somewhere or leak out?
This circuit has had several repairs due to leaks and other component failures including a compressor change out within the last year. Our estimation is that during the duration of all of these events it led to the oil level getting too low in the system.
Pls explain high motor temp 2
Pls when checking the oil level will the unit will still be on or off
It has to be off.
Was the chiller low on oil, or was it trapped in the evaporator?
To verify it wasn't trapped. We were able to get the circuit to fully stage and run for a few days. Even after adding oil we made a return trip to ensure that the levels did not increase.
Just a thought I carry A clear hose for those checks
We do too, the one we had on site failed at the connector so had to swop over.
Where did the oil go though? Does it mean there's a leak?
This circuit has had several repairs due to leaks and other component failures including a compressor change out within the last year. Our estimation is that during the duration of all of these events it led to the oil level getting too low in the system.
@@HVACTIME ok thank you!
