I didn't realize there was so much difference with POE. Your video really demonstrates the point. thanks
thanks I know a lot of 410 a compressor dying prematurely due to improper installation causing the oil to coagulate and prevents proper lubrication
I'm a little late to the party but this came up in one if my searches. I always wanted to try this but put it on a hot plate to simulate a cc heater and see if that would assist in removing the moisture.
Some more tests would be cool. Weight before and after. Try with heat also.
Nice video, tanks for the demo.
I was afraid that jar would break. But it could be worst, ask the guy in 1 man 1 jar 😂 he'll remember that jar break for life
Would have been cool to weigh it before and after to see how much water was left. Cool experiment
I tend to agree with JB, introducing heat might help the process. Good video.
What about pag oil? Is it worse than Poe or is it better?
Could we warm or heat this oil for removing moisture, if than , how much heat it can be ?
Thank you for posting!
awesome video, thank you for posting this!
Eric Anderson thank you for watching
How about keeping it around 110°C for a few hours? all the water should evaporate.
excellent video!!! Thank you.
+Mercurio Sanchez thank you for watching
Can you let it go through different sized filter driers to see how the right size for what amount of water dropped in? Thank you
Wow Poe oil holds a lot of moisture no wonder those lg refrigerators breaks down so much lg doesn’t vaccumm them right at the factory before they seal unit
at how many microns the pump stuck because of the moisture?
Good video, bud
What vacuum levels were you able to achieve at the different times? Curious if you couldn't get below a certain level because of the moisture.
The main thing to learn from this is that once the moisture is in the oil, it hides. I was able to pull a vacuum down to 200 microns on a system that sat open for I don't know how long. The moisture hides under the oil and will allow you to get a nice vacuum pulled, then when you start the unit up the moisture will begin to mix with the oil and cause your burnout.
I removed poe oil from a compressor that was used for a walk in cooler, after 1 minute it started to bubble. I think it was acid but not sure, let me know what you think.
+obedb093 if it was bubbling it room temperature it was refrigerant that boiled off due to the higher ambient temperature and pressure
How do you test to find out what oil your system contains?
What is the CFM of your vaccumepump? Thanks.
when vacuum is ruing can heat oil to remove moocher
If you can heat the oil, the water will boil off a lot quicker for sure. When vacuuming a system that has been left open or had a punctured evaporator, I remove the filter/drier, do an oil change if possible, blow out the system with nitrogen, then seal the system. Once the vacuum pump pulls down you can judge if there's still moisture stuck in the system. The best way to do it is to heat the bottom of the compressor! A sudden sound change from your vacuum pump is a dead give-away! Otherwise, a pressure that just won't stay down is another. I often heat every part of the system that I can reach if there has been a water event. The compressor can take quite a bit of heat and is often where most water collects. Sometimes running the compressor for 5 or less seconds every 5 minutes can also speed the process. By the way, once I am sure the system is as dry as I can get it, I break vacuum with nitrogen, install an oversized filter/drier, re-vacuum, recharge and watch the system. Sometimes I'll go back a couple of times to change the drier to be sure it's dry. I had a system on a drive-in/walk-in that was left open for a year. 10 ton. (X 3!) I found water in all the compressors. I did what I outlined above, and left them in vacuum for 7 days. 6- V-Pumps total! 6½ years later, still no refrigeration trouble! I must have got that one right!! LOL Good luck!
Heating with a heat gun for an hour or so . Also install in line moisture checker glass
You totally CANT remove all the moisture from POE OIl… So your basically screwed
Why did they stop using mineral oil when it was proven for decades?
Buell Ah because a lot of hfc cant be mix with it
Buell Ah
Simple English: The refrigerants that it is used with will mix with it to carry it around the system. Mineral oil is used with the older refrigerants because POE wont mix with them. Short answer: You have to use oil that works with the refrigerant being used.
somehow I am watching this old video....this video is completely misleading. The vacuum only removes dissolved gas from liquid, not water vapor! the bubble that coming out from the liquid is just air mixtures, it may have a tiny amount of humidity in it, but most of the water added to the oil will never be separated by vacuuming. Heating to 100°C can. A simple way to prove: you put only water in the container, and vacuum it, see if the water disappears......
