Refrigeration: RACK with Load Issues with Brett Wetzel

Rookie Refrigeration, it was humble of you to be trsnsparent enough in this video to show that you needed troubleshooting help with the loading/unloading issue. I appreciate your honesty and openess. As technicians, we all inow what it is to encounter a problem that stumps us, causing us to need help at times. None of us know it all. Good content in this video.

Now that's a guy to have on speed dial

I’m really learning a lot about the Emerson RACK system thank you very much for showing me this I appreciate it brother

Thank you for sharing. That’s a good find. Ive Been working with racks off and on for about 4 1/2 years. Great video!

Very interesting. My first thought was maybe low refrigerant but those racks are way different than my understanding. As far as cold OKC is worse right now. Ice, accidents, COLD and getting colder and now they are calling for 6-12 inches of SNOW... I wish I was getting on a plane to Jamaica today or headed to Galveston to get on a ship for warm waters. But it's amazing how temperature extreme's will cause issue to creep up. I bet that this is probably the coldest that rack has ever been since it was installed. Good that you have someone to give you a hand on that though.

Thanks again for your time making educational videos never is too late to learn

That type of support is priceless 👌. Keep the videos coming 📹 great info for us new guys.

That was a awesome video!!! Sounds like that man has that E2 book and some memorized!

Good vid ! Hey Rook , The Reason the Condenser is a Distance away From Rack is Roof Load. Engineers Like to Spread the Roof Load , Vibration , Noise , Harmonics etc. It’s a Good idea. Helps stave off Cracked piping etc too. A LITTLE distance is a Good thing. Multiple compressors , feeding multiple Evaps , under hugely Varing ambient conditions and case load conditions is Sometimes Tricky especially if the system has Modified since design & installation / Cases added or removed / altered. Extremely Low Load conditions are allways tricky. I Remember back in the day ( 80’s ) no rack control system. Oil Return problems with tandems under low load conditions. It was always a pain in the derrière. ( Ftngot ) if possible , Try to only install One Evap to One compressor systems. Multiple evaps to multiple compressors is ALLWAYS TROUBLE & expensive.

Great video very interesting. It’s always good to learn. I wonder who would have changed the dip switch settings.

134 a is a horrible refrigerant for grocery stores

Man I just learned a ton from you & your co-worker! Thanks for sharing.

Cool video. A lot of info to learn and study.

Hey Rook , Good vid. Watch your short cycling of Compressors when making adjustments. Sometimes pressures are Raised & lowered on each end to Give the compressor more off time & more on time. Tightening the Graph CAN be a Bad thing Most times.

Who changed the dip switch setting in the first place I want answers ? Good job Bret.

Mann this was great info!!! Thanks for the video!! 💪🏼💯

Nice work guys. Thanks for the video.

Great find

You guys rock man. Great video. Do you both work together? Edit: I now know who Brett is. He's a legend. Advanced refrigeration podcast. Thanks for sharing this video!

Great video 👍
