I'm looking to join local 94. I have no experience. A friend of mine is in local 94 and told me the best way is to attend the Turner School, get my certs, and I'll find a job. I found a job opening for helper with Tishman. Was wondering if the way my friend suggested is the right way to go or to go the helper route?

Could I please get an explanation from someone in regards to the following condenser pipework. I’m curious as to why they have added the reverse P-trap on top going into the condenser.

My guess would be even distribution of gas? Schrader for non-condensables? Possibly something to do with the oil?

Any truth to this?

Mine is monday - friday and rotational weekends on call. Calgary, alberta.

It’s just a bummer sometimes coz you never know what time you’ll be home specially if you’re replacing a bunch of compressors on friday.

I’m a Supermarket Refrigeration Tech with 14 years in the trade but i forgot what these sockets with 2 stubs on top used for? I remember having to change some sort of valve out years ago. An old timer had these sockets.

Have you used these quick disconnect couplings from Craft? I’ve noticed them on Norlake flex line connectors and Hillphoenix display cases during the past few years while repairing the units, and it seems like they may have resolved the major leak issues associated with Parker couplings. This product seems pretty dope.

Someone pissed off a brewery with their prices.

Hey guys!

So i'm from canada, and i started my own company a few years back. We build 12v fridge for campers and RV's and we are curently using MO or R134a depending on the fridge.

My question is: i want to step up a level and learn how to use r600a, but i can't find anywhere how to use it, where to buy a tank, or any training related to this specific gas.

Anyway, if any of you know a way to have a proper training or formation and where can i buy a tank, let me know!

Thanks!

Got this new job. Took a slight pay cut for it to get out of fixing shit at McDonald’s and Burger King and I got my wish. It took all of one day in this new job to realize how far out of my league I am. Booster pumps, chillers, medical refrigeration. Any advice for someone transitioning from restaurant refrigeration and hot side to the medical side? For example I’m told we’re gonna work on a reach in and I’m like “oh sick something I can actually help with” and it’s a friggin blood bank or something at -72°C! I’m used to little capillary systems running -10°F at the lowest. Thankfully I’m just riding with someone right now but I’m kinda anxious about going on these things by myself. They DO have a spot for me doing hotels and the local schools which fits in perfect with my ice machine and small refrigeration experience though. Sorry dudes I don’t wanna make this a diary entry but I need some advice!!

Hope everyone’s well. Just wanted to test my luck and see if anyone in Toronto is willing or knows someone willing to take me on. I like to think I am an honest kid with a good work ethic. I’m 23, got a car and write my g2 in 4 weeks. I’ve got lots of resi trade experience but mostly carpentry and plumbing. Unfortunately I’ve barely worked on refrigeration stuff outside of RTUs.

Honestly In this humbling job market I’ll take any opportunity to learn and be of any help. I’d be grateful even for just an interview. Thanks for reading this far and I hope you have a good one. Cheers!

If this doesn’t fit community guidelines please let me know and I will take it down.

Say you’re working on a walk in cooler and box temp is controlled by low pressure control. Desire to have 35 degree box temperature running R404. What can I put for cut in and cut out?

Saw this pi-diagram of a cascade system on a small -80*c freezer

So our buyer ordered Danfoss PT1000 sensors in cases for a store with E2 controls. Does anyone know what I need to use these sensors without buying the Emerson adapters?

I am a consumer protection attorney looking for someone with expert knowledge of commercial refrigerators who can testify in a virtual (Zoom) hearing on November 20, 2024.

You would be reimbursed for your time at your normal hourly rates.

I am looking for someone who can testify about whether a fridge with 115 volts and a total load of 7.4 amps is a commercial grade fridge. I am specifically looking for testimony about whether a fridge with this voltage and these amps would be considered "commercial" or "residential." The specific fridge is a Traulsen UR 48 HT.

If you have expertise in the specifications of commercial fridges and are interested in being an expert witness on this point, please shoot me a message on Reddit or an email to: lorraine@kneuppercovey.com. Thank you!

(I do not believe this post violates any of this subreddit's rules, but if that is incorrect please let me known and I will take it down immediately.)

Had a service training meeting that evolved into a manager meeting today. Learned the term KPI. Key Performance Indicator. Not sure how to feel about this. Also learned we have a new player in the refrigeration field here. NEXTECH!

Been using my testo probes and everything’s been great, my suction probe started to display the red LED which means low battery, replaced batteries with brand new set and can’t seem to get it going, blinks orange for a few seconds then goes back to red flash, changed batteries 3 times, any ideas?

Sometimes I wish I could get an AirDrop, so I did’nt have to haul the whole van to the roofby myself..

The charging probe broke off my yellow jacket wireless manifold. Does anyone recommend the new JB wireless probe gauges? Fieldpiece? Something else?

So I work as a refrigeration tech. Been doing it for 14 years. I live and work in sweden, also did 4 years as a tech in Argentina/Chile.

In South America they have some tech that only work with hvac and some only refrigeration.

But in Sweden it dosen’t exist… everyone is a ref tech. We do everything, comercial ref, restaurants, heating systems with water radiators, air conditioning, co2, small winecellar.. you name it and anyone at my company will fix it. Obviously some has more experience that others.

The only thing most people don’t do is R717. We have like 5 that only works with ammonia.

Why do you guys in the US just take on one thing? Like only Hvac, only commercial, only co2, etc etc. Is there a particular reason?

I have this understanding after been reading here on reddit.

Sorry for my grammatical errors.

Bonus points for the old Gordon recip in the background?

Started acting up. Doesn't read right anymore and wasn't sure if there was a simple fix.

I like to listen to true crime or music, makes the process go by faster
