Trane RTAC Leak Repair + Oil Filter Part 1

What could have been a pretty quick fix turned into a lengthier ordeal when isolation valves on a Trane RTAC chiller didn't hold. Leak Repair + oil filter change on screw compressor. Like, comment, and subscribe for future uploads. Will post follow up video when job is complete.

This guy has been running hvac for over a decade definitely a guy to watch

[@dfwhvac]

Thanks bud , back at you. Sick gaming channel

[@ChingusTheOneAndOnly]

I’m watching, Great stuff on here , Thank you , This channel should take off soon

[@AGON17]

I don't know how all these large commercial CZcams accounts went under my radar til I started searching for CGAM and RTAA videos

[@markcotter2355]

good job from fellow DFW tech

[@dfwhvac]

Thanks watching ! DFW techs are bad ass 👍🏼

[@TheMaintenanceNetwork-DallasTX]

Keep doing your thing!

[@niggadonthatethis18]

Great walkthrough! Great information!

[@dfwhvac]

Thanks my guy ✅

If that was a semi I’d say oil looks like 10+ years old/or dirty system/or running hot.
Pre normal for a screw chiller tho considering compression ratios, you’ll get that darker tint on the POE pre quick from the elevated DLT

Great video man! Thanks now I feel alone more confident cleaning the oil filter.

[@dfwhvac]

Great to hear man and glad I can help ! They’re intimidating at first but if you have someone show you how to do it it’s not as hard as you’d think ! That’s why I make these videos

Thanks for thus great tip to keep the chilled water pump running when on recovery mode,I know that this has to be done when breaking a vaccum.

[@dfwhvac]

Yessir , recovery and charging should only been done with verified water flow on chilled water systems to prevent potential freezing issues in the tubes or heat exchanger

[@joshstevens9826]

Coat the entire gasket in oil , nylog, or what i use vacuum grease. Will be easier to get the gasket off next time.

[@kennethlobo4420]

Thanks A lot enjoyed watching this video.found ur cannel accidently

[@dfwhvac]

Thanks for watching

[@ChingusTheOneAndOnly]

Great content , Thanks for posting

[@dfwhvac]

Thanks for watching . Been busy on a contract that doesn’t allow filming on site , but will try to get some more content out soon.

Nice work 👍

Great video I’ve never worked on chillers, always been curious as to their operation. I’ve worked mostly on supermarket refrigeration and for the most part I was able to follow along. We have oil filters and the same kind of drier cores. What would you recommend to learn more about chillers?

[@dfwhvac]

Read Manufacturer IOM manuals. They are usually much more detailed and in depth as far as each operation of the system when compared to regular DX cooling units. There’s also a great channel called HVAC TIME . He works on chillers a lot and is very knowledgeable

[@JM-wk2tz]

@@dfwhvac great advice thanks !

[@jevonhoward]

Trane has a training class specific to the RTAC chiller in LaCrosse,Wi.They spend 3 1/2 days covering everything front to back if your Company is willing to pay for it.

[@fkdeazevedo]

Is that where you add too?

[@diegoandrade5953]

Hello, about the compressor low oil flow failure. my chiller has 2 compressors on the circuit and one of them has a low oil flow alarm. the oil level is ok. what could it be in this case?

[@dfwhvac]

Depends on the make and model
Of the chiller and it’s components. But it could be a dirty / clogged oil filter or strainer or oil pump not operating properly if you can visibly see oil in a sight-glass

[@joshstevens9826]

Dirty co dessert coils can give you an oil alarm. Cant remember the numbers, butnif the oil temp is close enough to SAT discharge temp it will alarm on oil flow. Usually tranr uses the top couple rows of the condenser for oil cooling. So dirty coils will give you elevated oil temps

[@jevonhoward]

If its a RTAC, more than likely the oil filter or check valve that sits in front of the filter.The IOM has the formula to calculate the oil flow ratio.If ratio is too high you will get that alarm.Also make sure transducers are reading properly as the computer is using transducer pressures to calculate the ratio.If high ratio is confirmed, I would replace both the check valve and the oil filter since both involve pumping down and opening the system.2" deep socket needed to replace that check valve.

[@jasonjohnsonHVAC]

Did you send the oil in for analysis by any chance

[@lammaking333]

No sir we did not . But we came back a month or two after this call for all the chillers on this school district and submitted oil analysis as part of the annual pm

[@jasonjohnsonHVAC]

@lammaking333 nicely done...oil analysis is a big key to spot a potential major issue

[@ajajomedia1220]

Is that chiller also

[@dfwhvac]

Yes sir , it is an air cooled chiller with screw compressors . R134A refrigerant
