WALK IN FREEZER TEV REPLACEMENT 

no wet rag on the solenoid valve? I will drop an evap unit to work on a bench - takes longer but I get it built up nice

That Sporlan kit is excellent. Organization is essential to saving labor and time.

Another comment in regards to the sight glass. Put it upstream of the filter dryer. With age and use, the filter dryer can cause a pressure drop and flash gas even while the charge is correct. With a roof unit the weight of the refrigerant will take care of the flash gas before reaching the expansion valve below.

Walk-in coolers I like to use Penn A19 electronic controllers. I get tired of screwing around with those manual thermostat since not much more work. I have a wire ferrule kit on my truck that makes it really easy 2 hook it up into that small wire connections. Walk-in freezers we have a few of those are not as critical but if you had a freezer that was a critical temperature I would put a electronic control in that as well

No reason to recover it?? Just use the existing liquidline valve to pump down. Then if needed just add another drier on liquid line after king valve and you must wet rag solenoid valves... of Danfoss type, they have a fibre disc inside that can melt.. dont know about sporlan soleoid though

I did my apprenticeship not in service but in building chillers, mostly for laser cutting application. Happened that I also did half a year doing service work and after watching a lot of videos on your channel I am so disappointed how much harder the job got for my colleagues and me just by not having tools nearly as sophisticated as you can present here on this channel. Such small stuff like a micron gauge that has no problems with positive pressure, so it can be easily removed without disturbing the vacuum. Stuff I had to verify complicated or had to make assumptions on, you can present clearly just by using the right software and probes. If I ever have to go back I take a huge amount of inspiration from your videos.

We only use straight acetylene turbo torches here , they work well and I don’t have an 8” flame spitting past my weld, why does everyone use oxy acetylene ? There is no right or wrong, just wondering.

hi chris --has always great video thank u so much ----that boxe looks very very nice and relabel

Your not alone l was always favor of Sporlan wasn’t big on on Alco valves.Why didn’t use a electrical thermostat haven’t use an A19 mechanical thermostat for over 10 years them thermostat they get out of calibration essentially when you have the heath inspection .

I rather dislike doing TEV replacements. Never enough room to work comfortably.

I really enjoy your videos. Thanks!

Dude, your channel rocks! you truly are a great technician, for real. I'm gonna watch all of your videos, keep it up brother!

I would rather be accused of using too much brazing rod versus chasing leaks. All the guys that ever bitched about my brazing chased leaks. Guys that do not know the difference between brazing and soldering and thinking a braze joint should look like a solder joint; plumbers?!?! Lol.

Nice Job

One of the hobby guys that I watch does this thing where he takes his solder and bends it into a rough ring then slides it over the piece he wants to solder. how well or bad would that work in a situation like this?

The one thing about cases i have never understood is why on earth can't they decide which standard to use? I get they don't want to pay licensing fees for proprietary standard but there are so many open ones as well... All my Tools are in L-Boxes, they are awesome, durable and very practical because to connect to each other and i don't think Bosch owns that standard because there are certain other tools that can be had in L-Boxes too.

At some point it seems like the fix to a flooding valve was just to add more refrigerant 🤷‍♂️

Keep the videos coming! Great job

Soldering has the same AWS definition as brazing, except that the filler metal used has a liquidus below 840°F (450°C) and below the solidus of the base metals. Soldering can be considered the low-temperature cousin to brazing.

I really enjoy your videos. I always remove the line set quick connect fittings, they tend to leak.

you could turn the liquid line valve around backwards, but I doubt there's not enough space to use the service ports. I wonder if it was just an engineering error, but more likely to be cost cutting tomfoolery.

Expansion valves and power heads. Nice sporlan kit. Good job.

Going from Frozen hell to literal hell must be a bit of a system shock.

Sponlan/alco valves suck. when failing they flood! a Danfoss does not fail often, but when it does it shuts off. also the Danfoss kit is much more refined and needs no oil or rubber gaskets. Great job though Chris, really like your videos. Nice to se how its done in other countryes

Did you get a new camera? This video seems to be *much* higher quality than some of your others. It looks great, keep it up!

Damn you man! West coast wanted to find a fault with east coast but you didn't let us! Go easy next time.

Really like that new carry case for the txv kit they should stick with it in my opinion

Nice job , Keep up the awesome work and be safe !

We call em TXV here 😁

Subwoofers beware of the Nitro tank. That's a deep bass drop.

better to start brazing upstream of nitrogen , just a suggestion, good videos

There is a rotating knife in those Webster pumps that takes the place of the filter screen.

I thought about getting that umbrella. Johnstone’s has it. Is it pretty sturdy?

what is that thing he's using ? VCRT? on the king valve?

Love your vids, keep up the good work.

Looking at the indoor fans it actually looks like a condenser it self looks like it’s built the same way as a condenser unit

I can see from outer space your a total pro with all the skills but DAMN why you selling them all those parts??!?!! Seriously tho. That bill is going to be half the price of a new unit. Let’s say another major or even med component goes out in the near future, which would not be surprising at all looking at that unit. Then what? More money??? That’s just nuts. There’s more to being a good tech than just fixing things. Respectfully

Hi

Always complete and thorough though you don’t address the real issue. Again, no pee trap! On your last one like this the system was full of oil when you did the repair including changing out the TXV valve. Simply adding the required pee trap would prevent the oil staying in the evaporator coil and more specifically restricting the expansion valve.

Anyway im a big fan of your work.

21 minutes when you need three hands...

love the new case, would love to see them stocked in the supply houses. They want to charge freight to get them.

I think Sporlan would be a good sponsor ... Lol ...Good vid as usual ... Much appreciated ...

Hello friend!....That cooling putty.....I haven't seen that before...what is it called and I purchase some from United Refrigeration or Baker Distributing?

Where did you get the HTPG coil number information from? Was it on the evap. nameplate?

Enjoyed the shorter outro. Thanks for the informative videos.

Those nitro regulators are the best! Love those things.

Hey chris , i sent you an email, could you give it a quick read . Thanks

Good stuff.

You should have a small step stool, and have a 3M mask. What's the size of the TEV? 0.5, 1, or 1.5 Ton? Another great video!

Have you ever thought about fitting Carel EEV'S to any of your walk in cold rooms and freezers?

I was taught to reduce oxygen slightly on the torch from a neutral flame to prevent an oxidizing flame that leaves pinholes, and the envelope of the flame will flux the copper removing the surface oxide. It is hard to tell in the sunlight. Are you running a small feather? I think you are as it is larger than a typical cone. The copper fluxed very nicely in the envelope.

Dude! That case is sweet!

Just curious do you use stay-silv or stay-clean flux?

I've seen what happens to a over pressure car ac unit. Kaboom .

NICE VIDEO DOUT! YOUR LUCKY, IAM WORKING ON STEAM AND HOT WATER BOILERS NOW. AT THE 5-6 MINUTE MARK YOU REMIND ME OF "REPO NUT", GOOD STUFF. THANKS.

Please what is the name of the equipments you use to collect the Refrigerant from the system I want to buy it. Thanks

The right way to do this is to purge nitrogen when brazing and your pretty much the only person outside of school I’ve seen braze with nitrogen ! Love you videos cause everything is done right and no short cuts cause shorts cut equal bad work

Very nice good job

Great video

Hi Chris, any help in shipping tools here in Philippines? I inquired in truetech tools but it seems they don't ship here in our country.

Gotta love the Ol Mechanical tstat. Good vid

Good work. Mohammed Algeria

Curious as to why there is no oil separator or suction accumulator? Here in Australia very rare to see a freezer with out them

Chris do you know anything about pro press. Basically dose not use a torch or flux

Another excellent job 👍👍👍👍

🔥🔥🔥

You make it look easy!! Good job!

Nice job...

hi, just a question for solenoid valve no need to keep it away from heat?

I always avoid putting the solenoid valve inside the evaporator case if possible, it just makes everything too crowded and uncomfortable to work on... I realize this was a R&R and you were trying to get it done, so I’m not bitching at you Chris... I’ve seen those receivers with no king valve, wonky setup, probably designed by an engineer who never was in the field before. Good video, thanks!

Just like a butcher....hacking away at pipework and ropey pipework to your expansion valve! Not a neat job at all.🤣🤣🤣
