What are your benefits like? I’m paid well, have great healthcare and retirement but there’s a couple companies I could see myself potentially working at that are union and that’s held me back from showing much interest because the pay is basically the same or less and pensions don’t seem super appealing to me and it’s not something I’ve experienced before.

I know every union is different but is medical completely covered? Like no copays or anything? Any other union specific benefits that you guys think are great in your shops? Don’t really know anyone in unions around me and just curious about what that side is like for you guys, would really like some perspectives from guys on this side of the industry about union work.

I’m specifically in supermarket refrigeration, do a lot of RTU/AHU work too and occasionally touch some industrial stuff just as a little background on what I do specifically. The industrial stuff has peaked my curiosity a bit and that has me looking into companies that do more of that and they seem to all be union around me.

Anyone by chance have experience converting a basic Express or any cargo van to a refrigerated vehicle? Any details, opinions, and info would be appreciated.

Question, can I replace 407f with 407c without changing the TXV in a heat pump? We normally use mo99 now but have to change the TXV and filter dryer. We have some 407c laying around. Some say you can some say you can’t just replace it. Not add to it but replace 407f with 407c. Can you do it? Thanks

Hi everyone,

I'll probably get dragged for this but here it goes -

I’m looking to learn more about commercial ice machines and am considering starting a side hustle focused on preventative maintenance and repairs. I came across this website offering training:

👉 https://etech.us.com/ice-machine-training-2/

It looks fairly comprehensive, but it’s hard to tell how good it actually is. Has anyone here used this resource or heard anything about it?

For some context, I work as a property manager during the day and already have a decent amount of experience diagnosing and fixing appliances. I’m hoping to leverage that background to get into this niche.

Would love to hear any advice, recommendations, or general thoughts on whether this training (or something else) is worth it. Thanks!

Whats everyones take on using supco 3in ones on prep table R290. Alot of these brands using chinesium parts. Making it impossible to find proper start components. I know they say everything should be explosion proof. I feel this is another leave service ports or weld em deal lol.

I have a rack running on 448 and l'm having issues with staying within set point range because of the glide. Discharge and suction pressures are good, as well as epr saturation. Any opinions about the possibility of replacing the 448 power head to R22 because of the glide.

Hi All

I'm new to the industry and I am trying to learn as much as I can. I hope of you guys can help. I've become interested in commercial refrigeration mainly from a climate emissions perspective and I am now interested in learning how the industry works more generally. Apologies therefore if these questions are really basic.

Some of the things I'm trying to understand from people directly working in the industry (from research I've my own hypotheses but want to valid):

• How who you say commercial refrigeration industry approaches maintenance? (Run to failure, preventive/ time based or is predictive maintenance becoming a thing?) Why is this?
• If you're a company that uses lots of commercial refrigeration (e.g. supermarkets) what are typically your biggest pain-points or complaints.
• What are the biggest challenges you see in commercial refrigeration industry at the moment?
• Commercial refrigeration is typically a big part of a company energy consumption. Do companies review this consumption at an equipment level or do they not care?
• Can you remotely connect to the temperature controllers or do you have to send people onsite to change parameters etc (or is this even needed - just install the system and rarely need to change anything).
• Are refrigerant leaks as common as reported? How are they detected and are they viewed as being a significant problem.

This subreddit has been a great source of learning thus far. So thanks to the community.

Currently an automotive technician trying to switch careers and possibly get into industrial ammonia refrigeration. A good friend of mine does it and enjoys the industry, but I honestly do not know too much about refrigeration other than the automotive side of it. Wondering if anyone in here has made the same switch and just for any advice and information about the industry. Thanks!

i got a hard time brazing alone without a helper to hold / push the pipe/fitting/component (txv for example), i can only hold the torch, and solder with each arm,any tools like a long metal crow bar, a vise grip bench that i can hook up, any tips or trick.

Where can I get the MT Alliance software? MicroThermo Canada hasn’t gotten back to me and Parker hasn’t a clue what that is.

Looking to gut all the carel controls in a large spiral and replace with MicroThermo. Currently utilize MT Alliance remotely on TeamView for a Large TC CO2 spiral and it works great.

i love these self contained decks that coca cola has, way better than taking the whole thing to the shop.

No question here. Just wanted to share.

Anyone ever buy a pallet to stick in storage?

Expecting the market to cool off at some point and looking for an alternative investment with no risk of devaluation..

If so any recommendations on a reputable bulk supplier for better prices than the local supply house?

This takes effect on Friday..

Good afternoon everyone. I'm actively looking for Employment with Contractors who do Refrigeration. I did a Year of Trade School for HVAC/R, and now have around 2.5 Years of field experience doing Supermarket Refrigeration (Parallel Racks, Protocol Racks, Walk-In Coolers and Freezers, and some Ice Machines, not as much there as Racks though) and Commercial HVAC Service (Rooftop Units mainly). I'm located in Atlanta, GA.

Grandpa left me an old Kerotest 513 manifold. Never heard of that company before. Found a Kerotest Frostline Vacuum box kit with the exact same manifold in it on Ebay. No actual information on its use though. Any info would be appreciated on the company and the use of these manifolds. Was thinking of refurbishing/rebuilding them for field use if at all possible

Hello.

I'd like to inquire about a replacement product.

It's a Nuire company.

The temperature is an Ult Freezer equipment that drops to -86°C and is a dual freezer.

The original compressor is KS370J1NS-7A PART CODE : 7FB-0-M101-001-06.

May I know the displacement (cc) or horsepower?

Or may I know the EMBRACO replacement?

I just finished repairing a big leak at the compressor discharge line. Vacuumed and added 15 pounds R448a. Went to the controller to set it for R448 and there is a 4 digit password for the “SETPOINTS” menu. I tried “1234” “1111” “2222”. No luck. Ke2therm is closed and I’d like to get them back up today. Any ideas?

Hello,

I am in Africa and have freezer room that has what I would call a failing compressor, I wanted to replace the compressor with a danfoss NTZ136A1LR1B, 208-230/1/60 but just realised our power is 50hz so now considering the NTZ068A5LR1B which is 220-240/1/50.

Two questions

1. Is it a problem? using the 60hz compressor in a 50hz electrical setup.

2. I was considering buying the danfoss compressors from Alibaba, is there a chance of getting a non genuine danfoss compressor?

Prices according to the suppliers on Ali.

NTZ136A1LR1B - $600 to $750 NTZ068A5LR1B - $500 to $600

If anyone knows other markerts I can look into please advise.

I cannot fathom why businesses choose to use Evac systems to pull water from cases. Sure install costs are lower, but instead of a simple floor drain, we get a system that has constant part failures. There's no way it's energy efficient, since the pumps run all day long. There's no redundancy at all. Pinch valves are usually mounted so high you need a lift. Fuck these things.

Stolen but had to share
