Replaced a compressor on a THERMO scientific reach in refrigerator. Changed compressor, condenser fan motor, and liquid line filter drier. All songs free at www.reverbnation.com/rasta1
A Thermo incubator showed up in the HVAC/R lab one day, after having been scrapped because of a leaky evaporator and bad compressor. The evaporator proved tedious but ultimately fixable, while the compressor would have been a much more serious problem. I'd set aside some scrapped refrigeration decks, and one of those donated its compressor to the incubator. Amazingly, it worked! The temperature control and stability on that thing, even running on what were probably badly mismatched parts, was incredible.
What was stored in these units? You got to be careful if chemicals stored in them. For special explosion-proof refrigerators they have to be labeled HFS and I saw the current 0/0/0 but keep those gloves on. As a former Chemist our lab units had nasties in them, God's sake keep those gloves on. Some chemicals go straight through skin and I saw some corrosion on the racks, a tell-tale sign. Under OSHA - no food allowed in a chemical refrigerator. I guess this could be a biology application.
Ricardo MAGARico Nothing worse then BSL 3 lab. Did all ultra low freezer -80c & W/I environment chambers . Even did the HVAC & containment machine room where all the water went down the drain they had to steam water before it went to the PH room .This even could of went to level 4 we had to certified the breathing equipment & maintenance never been used every year never been used.
@@hvacrnortheastern2110 The lowest temp ever saw other than liquid N2 was -40 C Methanol bath. Don't know what refrigerant was used. Kept in lab hood. -80 C mind bending.
Ricardo MAGARico Cascade refrigeration is different you must have good refrigeration practice there isn't any short cut -80 c which is -120 F degree.First stage is R404 & R134 second stage is R508B & propane for oil return one total rebuild takes 32 hours. Revco came out with Auto cascade -140. -150c which is -255F one scroll compressor with 6 different blend with CO 2 .If you don't have some experience with cascade it could cost you & company a lot of money due to the product store inside if not done right first time.All parts are OEM
Word to the wise substituting wholesale version compressors with -901 BOM's can get you in trouble when the -959 BOM's for thermo can possibly have different internal components and oils than their wholesale counterparts with the same model number. Certain Cascade and other comps. Are gauranteed to grenade with this path. You are probably good on that one though just a 134a system
Dave..another fine vid....what substance is inside the bottle for product temp? Also you told us a few years ago..but..I’m an old hvac/rman...what is the name of your intro song..I know it’s not “burgers”....thanks
Going back to Old School Manifold Gauges, you must admit using high dollar vacuum pump and hose set up with cheaper refrigerant manifold gauges just doesn’t look right. LOL
Nice super tech level vaccum there , sir 😄. Hey , so what happened with the fieldpiece vaccum pump , a couple vids ago you said it was sounding terrible despite the oil change , did you get a response from them , did you manage to fix it yourself ?
I use to service a scientific supply company. They sold test kits to hospitals. They had to keep their coolers between 9°c and 1°c per government regulations. The customer complained that that was unreasonable until I explained restaurants have to keep coolers between 4°c and 1°c. So 9°c was nothing. I think I have those celcius numbers right, but I still perfer farenheit.
FLY EAGLES FLY Bleed Green been in same situation. Crazy they put that kind of money in a small system... I worked on a walk in for a medicine distributor once and I didn’t even want to know or ask value.. crazy monitoring setup.
Since you here what would be the reason a bimetal thermal overload burns out? On 1/4 True GDM-10 cooler compressor. I tried switch thermal for a good one and they just spark and open the circuit. And even swap the relay & the thermal overload together just goes back to open. The thing that fixes is switching the compressor. Any thoughts? Also I check my ohms and check if the compressor is ground looks good but just thermal overload always goes open.

I’ve been workin on a lot of abs coolers for the pharmacies and it’s been starting components all week!
Always learn from you! Thanks Dave!
great video
Nice work right there
Good vid Super Dave ...
Another great video Dave 👍👍👍

Yes this lab use only.
Not an explosion proof notice internal fans that can spark.

Nice work Dave. The thermo scientific looks like a true or beverage air.
Yep glorified reach in.
That looks just like a Master Built.. Is it one of their off brands maybe?? Goooowd stuff..thanks Dave..be safe brotha
Nope manufactured in Asheville NC by thermo.

Oyeah I do the same. R134a blue marker...404a orange marker. R22 green...GET SOME

We luv the lurkers
It's glycol
Why don't order whole condenser set up plug and play
Whats does mean #1 & #2 in compressor app specs?

The check still looks the same. 🤣⚡️🤣⚡️

It was the recovery machine. I made a video of adding oil to it per manual, and it sounds better.
@@NorCal-refrigeration Oh shoot , I don't know how I missed that, my bad ! Glad it worked though .
good viid bud.
Thanked for info on Copeland app
Do they sell cannollis out of that case? Woop Woop.
Area51 compressor
Nice job dave
tell lab ppl i back tomorrow to find out everything work, than close w/o. is this job they give you all day ?
Hey Dave how crispy do you like your compressors kfc original recipe or kfc extra crispy lol Have a great one my friend.
🤣😂🤣😂 extra crispy always
@@NorCal-refrigeration ROFL

When I worked at the grocery store the dairy cooler was always close to, but above freezing. Those temps sound correct.
Surprised that there weren't stainless shelves in that box. If it were a food service box the health dept. would ding them on that.
Just experiments in there
2009 unit probably in an acidic environment
👍
Cooool
Cheaper compressors, higher prices?
No kidding
I use to do CVS.. man one time it was 1million worth of pharmaceutical medicine in a two door..I almost crapped my pants when they told me.
FLY EAGLES FLY Bleed Green been in same situation. Crazy they put that kind of money in a small system... I worked on a walk in for a medicine distributor once and I didn’t even want to know or ask value.. crazy monitoring setup.
you sure that wasn't the compressor oil return line :)))))))))
How's your keto going?
Never did keto yet. But probably should lol
