I dont even work on racks, but working in the industry i know theyre out there and one unfortunate night im going to end up in front of one. Youre a wealth of knowledge when it comes to this side of the industry, thanks for sharing this stuff. Im no rack guy but understanding how they work is interesting.
How long roughly can you have the oil reservoir shut while performing the replacements before it can cause oil failure? And how does a faulty OCV affect a system? Thanks!
Great video. I never touch the flare nuts doing the filter. I don't think it's necessary. I losen the support bracket on the housing and drop the bottom change the filter and gasket and slide it into place. I touch flare nuts as little as possible and no bending lines out the way.
I too also lean on the side of caution. If something that could be done to help ensure the quality of your repair. I always try to include it unless things I can’t control stop me
Were u talking about the hygroscopic mix polyester oil has in it like r410a and iirc 407c? I think in certain states we label our mech parts a bit differently, I'm use to oil receivers and accumulators, and for me I was always under the impression that oil separators are on EXVs that don't fully close(unless u got EXVs around ur headmaster valves for head pressure control). What do u think? Btw I dig ur vids
Yes that is the kind of mixture I was referring to I just couldn't think of the word. I mean it's possible that some type of oil system could be done that way. I have seen oil systems with reservoirs done in two main ways personally. 1) with the check valve I showed you up there in the video. 2) they will have an oil differential valve that looks just like a TXV. This valve will lower the pressure of the oil which is at discharge pressure before the oil differential valve. This setup would be used because you could use three different oil differential valves for three different suction groups. I hope that makes sense and answers what you were asking. :) Also thank you for the comment and the compliment it's very encouraging :)
This is a low pressure oil system. Other rack systems are high pressure. Were you having reservoir oil return issues? Check suction filters at compressors. Shouldnt be any in the shells. Remove schrader and probe with a piece of silfoss to check. Sometimes they arent removed after start up. This can easily be an oil issue. By looking at the oil filter this could be your problem as well.
👍❄️💪🇺🇸 Great to c ur well. I’m focused on commercial refrigeration. N by that I mean walkin/reachin/glycol system for restaurants. I’m Sure I’ll shoot u n email from time to time with questions. Go flyers
Wow ... what a load of information this guy is sharing! Been watching many of his older videos. Thank you!

That’s funny. I can definitely relate.
2:53 think you are thinking of Miscible.
Love your vids man!
Thanks!!! For helping me become a better tech
Amazing video ! where in BR (BRASIL) there's a lot o sistems like this and I love keep this Racks operational. Thanks for share this informations.
Your welcome :) I'm glad it helps you 😊
Excellent! Glad you're wearing some PPE.

Thank you for the share that's good information:-).

Nice work. Looks like a walmart.
Any pressure differential that ofe is gone
Thanks make more videos were there a service call or p m.
Did you have to shut down the rack temporarily?, to change the ocv valve .
I don't believe I did,
The compressors will just trip on oil failure.
You could shut it down if you wanted.
Thanks for the tip, brother
What's the best way to test the check valve if i suspect it's not working properly?

This is a way to do it hope it helps :)
Awesome thanks
Have you worked on any Co2 systems ?
Not yet I hope someday though
Mastery!

Great comment man thank you this is excellent stuff :)
It's sucking wat oil or rifigerant and why
Not sure what you mean?
Maybe time stamp?

No oil bath today….🤣
Lol not today 😎.
Hell yeah
What's the hurry? lol! 😀
🤣
