Equipment 4 - Parallel Rack Systems 

I think this may have been the best explanation of headmaster I’ve ever seen. I might have more compliments later but I’ve only gotten that far.

Super great information. All you young guys should eat this up. I never had a chance to have so much info shared with me at one time.

Absolutely superb presentation, extremely interesting and informative thank you.

This is great to have because it's online - you can STOP, rewind, take the time to study the diagrams, then go back and replay the dialog to match the dialog with the diagram.

Excellent communication and explanation! Systems approach always wins. Keep up the good work

Thank you for sharing this, im hoping to move in career and have never worked on a rack system in my life. Great info and I feel a little more prepared for my interview

Great explanation!

Thank you so much!!!!

Marvellous...

For the beginners watching this, don't expect yourself to be able to "pass the test" for the this video. It is for people who already know the reefer business. Nevertheless, after the 2nd or 3rd play, try challenging yourself by just listening to the audio and see if you can follow flow and jump-arounds, sentence by sentence, and clause by clause.

Thank you. very educational and a good way to get my feet wet.

Cool lot of good information. Thank you very much

Great information thank you for sharing

Great video

Thank you very much for this video.

Really enjoy ur videos thanks for sharing ur knowledge

I like the video and yes i want to be expert tech on rackroom and especially on co2 cases.

Great

Nice work 👍

Thanks for the video, for the walking freezer with very low temp, what would be right superheat

Thanks heaps for this info mate, I'm watching this from Australia and everything here is similar too what you've demonstrated. This may be a silly question but.. When you were talking about sizing the rack appropriately and saying the biggest compressor doesn't get alot of run time due to it being almost like a back up, and stating that oversizing back in the day was problem. Would it be beneficial NOW to oversize a rack today and just have some VSD's (Variable Speed Drives) on the motors to reduce performance/amps/compressor speed etc? Pros and cons? Thanks again for the info

Thanks, does it matter what type of condenser (air-cooled or water-cooled) we have to decide about our subcool and also would it make a difference that we have very low or medium temp walking freezer to decide about our superheat

Strong content

Thank you sir

Super

I am getting starrer in supermarket refrigeration.

2021. still selling R22.

These guys are "doers" first and "teachers" second... That's ok, but as a learning experience, it could be better. I'll have to watch this several times to "get it" - can't keep up with the complicated flow-diagrams, then the overly folksy "your xyz valve" and "your xyz meter". But here on RU-vid we can stop/rewind/repeat. "It's a start."
