Refrigeration Rack Overview w/ Sped up Oil Change

[@charlesjohnson1456]

I like this. Seems like so few rack guys do videos or podcasts and now that I'm doing markets I wish there was more of them to listen to. Keep it up!

[@anthillmobstars]

I hope we start to get more refrigeration videos. Love it and the Podcast.

[@jimmyp5487]

Been doing hvacr for 20 years and starting to move into supermarket… great videos brotha I really appreciate them and they def help!! 🤘🤘🇺🇸🇺🇸

[@apprenticephil649]

My knees hurt just looking at these guys wrenching away. My boss had both knees replaced at 65. Knee pads boys. Amazing video. Thanks for the walkthrough.

[@zacharywoodford8530]

Awesome content. I just got my first hvac job out of school and it's in supermarket refrigeration. I feel like I'm way over my head here so this is incredibly helpful

[@gamble8917]

2 weeks in to commercial refrigeration. Feeling this comment pretty hard rn😅 how you doing being a year in?

[@michelgrenier1878]

A very thorough oil and drier change , It's nice to see a customer that is spending the money to properly maintain his refrigeration equipment .

[@andrewschaefer8863]

I am loving the refrigeration content. Keep it coming!!

[@zombiediarhea]

My forearms and elbows are eat up with discharge line burns. The engineers that design most of these racks apparently never had to wrench on them.

[@Ismael72110]

nice man !! keep posting more refrigeration stuff !!

[@SokoNK]

I've noticed that you didn't change the seal on filter shell cap. Few new seals are usually delivered inside of the can together with new filter core and it is very important to change them each time you open it. I like to put few drops of oil too which, I believe, helps new seal to "sit better" between metal surfaces. Why it is not allowed to use Brake Cleaners? I used R141 before it was banned and now I use only clean rag and dry nitrogen.

[@leonbogon148]

great video for new techs to see-things haven't changed much since i was servicing systems---except refrigerant shuffling-looks like co2 and hfc''s or future--keep vids coming-thanks

[@Blinx559]

Great rack video. Best I’ve seen yet. Please keep em coming 👍🏽

[@texture6]

On point Bryan! Thank you for the knowledge

[@johnd4348]

Were I work they send hvac guys out to work on racks and expect them to know how all this works and do it in an hour. I see you have several guys. My company would send one guy out and expect it be done in half the time it should take. And they wonder why equipment fails.

[@886888aa]

Can't believe that rack has CDS valves. Must have been a retrofit. My guess is if the oil is acidic and breaking down the system is probably running high super heat or high head. A system running properly doesn't need an oil change unless your changing the refrigerant.

[@itsmemsti]

Not a big deal most of the time, but the "liquid line" from the condenser to the receiver is called the drop leg or the drain leg. Out of the receiver, now it is the liquid line.

[@HVACS]

Yes, I mentioned it is called the drop leg... I didn’t mention drain or drain leg but it IS still the liquid line either way based on the basic refrigerant circuit even if it isn’t called that by rack techs

[@JW-me2po]

Thinking of moving from restaurant ref after 17 years to supermarket work.

[@fernandominaya4933]

Thanks Bryan for share your knowledge. I appreciate it

[@johntyszka2980]

An HH drier is used for wax removal after a burnout. If you are trying to remove acid from a system, the standard 4864 drier is the correct drier to use. This has been a misconception in the industry for years. Check Sporlan or Alco’s specs on their cores. They will tell you the same thing.

[@JoseGuerrero-sj5ie]

Nice video thank Bryan orr

[@hvacrider7181]

Thanks for the video, a good tech always admit there mistake .. well done.

[@tonymckay9031]

Enjoyed that video, thanks! A lot of good explanation.

[@nojiggle530]

Lol i have been using those thumb style core depressors since i started the old guy who taught me 12 years ago swore by them loved them since but could never convince another guy to use them no mather what evin with ball valve ends on top

[@Nostalgia2x]

great video. what chemical is being used to clean the oil filter screen in 11:31 of the video

[@jaysongoff]

Those hot oil loops inside the suction header had a tendency to crack/break, so Hill and Kysor Warren discontinued them. We in the service industry unhooked many during remodels and retrofits. Whenever those would leak directly into the suction header, many issues would ultimately present themselves. The service tech then would have no choice but to abandon the loop.

[@hangngoaigiare]

So i would like to come and have some hand on training on service and installation of this rack system. Please tell me how and what the cost.

[@squirtlehvac8962]

Great video👍🏽

[@briancarlisi2224]

Rack refrigeration has a lot going on! What is the tool you had that just depresses the core to allow refrigerant or oil to pass? Thanks for sharing!

[@HVACS]

BluVac / Accutools Core depressor

[@hvacrnortheastern2110]

Good video this video brings back lots memory's did rack for over 6 years on majors Supermarket chains.

[@lacasadelsolresort9249]

deez

[@hangngoaigiare]

Hi you do hand on training? What is the cost for that?

[@neilvestervictor180]

i want to learn supermarket refrigeration its interesting the methods you use are u base in florida i work on chill water systems looking to come to the states to study looks like it might be florida

[@jedidiahlawton2149]

Where was the torque spanner?

[@joeshearer1247]

Did he say OCD valve?

[@tonymckay9031]

😂

[@cesar235cs]

I heard OCV, and most likely is a 20. I don't front seat discharge valves when I do oil change, if it leaks back we have a plate problem. I also remove sentronic sensor and clean strainer

[@scottkasper6378]

What’s the core depressor tool called?

[@anthony262]

Good old publix.. looks like a 400 series store

[@ralphgiampietro85]

Why are the liquid lines on the condenser doubled trapped as well as the condensers shown in the vid were at the same level as the motor room which can lead to gas binding you really don't have a free draining liquid leg especially with the liquid line trapped?

[@loralkinney]

I'm surprised as an owner that you all were not wearing ear plugs...as one who developed hearing loss I urge you to think ahead....

[@WarHammer1989]

Loral Kinney I saw orange earplugs with some of the people

[@SombraLocs]

I hear some people say, "oh I'm used to it, it doesn't bother me anymore". That's because the damage has been done.

[@randybirkeland3331]

The key word being "some". A proper OH&S safety program would make it mandatory. Decibel test before starting work. Company safety manual would dictate at what level hearing protection is to be worn. Definatelt would be required here.

[@kennybakerhvacr5751]

what was the name of the tool bryan handed to the guy? he made it sound like a core removal tool but slightly different

[@Practicing_HVACR]

Kenny Baker HVAC/R schrader depressor tool

[@Jonathan-bl8oh]

Big man was wearing two t shirts... making me sweat just watching

[@WswRefrigeration]

Link to that access valve were using?

[@tonymckay9031]

Trutechtools.com search accutools shrader depressor

[@areminfoxxtrot1064]

This looks like a Publix.

[@вечная_мерзлота]

I thought hvac techs don't go near a rack unit.

[@maness2112]

I love to hate supermarket refrigeration.

[@deviouslick5097]

Amazing video. I would love to work on these.

[@maness2112]

Not that much fun.

[@ndm19891268]

Those suction line are not insulated 😳

[@russell4309]

👍

[@salmanmakanjira]

For the fact that it's for learning purposes,fast forwarding is a bad idea.

[@johnnysaltyaircrabcake8030]

OMG Hill Dual Mates.... .. They still chug along as they have maintenance done.... energy users and leaking monsters.. from our end

[@6Diego1Diego9]

Do you get a lot of girls as an HVAC technician?

[@TheMaster5150]

Your guys should be wearing gloves working with solvents.

[@JD-hr6dr]

I came here to say the exact same thing.

[@holdurhorse9149]

Generally oils and salad dressings are located on aisle 7, we don't carry liquid line but just bottled waters. No hot gases either sorry sir!

[@cameron3991]

I would take that ring off if I were you, you need a rubber ring that will break if it gets caught in anything. You are going to lose your ring finger if you do commercial hvac for 20 years and wear a ring iike that

[@ares3914]

I notice a lot of techs dont wear gloves when they should. These chemicals is bad for the ozone so imagine what it does to your body
