i had a yong heng compressor for several years and it worked great for my needs until it broke down the other day . i watched a few videos of people who tear down there yong heng compressors because they broke or for whatever reasons . there was a video that showed how the water was making the aluminum inside where the water runs through the heads started to flake or break down inside . he said the water is what caused this to flake or break down . is there any type of additive to add to the water to prevent the aluminum from breaking down ? i was thinking instead of using water can you run a premixed antifreeze that has been chilled like in your refrigerator or freezer ? maybe this way the yong heng would last longer . do you think a premix antifreeze would work ?
Yong Heng compressor question

- Start date
I don’t know if you used tapwater or not.But I think it would probably be better to use distilled water.

what about the premixed antifreeze ? has anyone tried the premix ? do you think it would work ?

I'd like to think the conditioner/lubricant used for airless paint sprayers might work. That stuff is supposed to prevent corrosion in those pumps after you clean them with straight water running through the system. That's just my thought. If one of you guys say no, I'd be glad to know why. I'm starting to research the YH compressors myself.

I was thinking about tap water also. I have a water softener so it makes me wonder what the added salt would do to the pump.

I’m going to see if I could find that video that shows the corrosion. It almost looked like cars with aluminum rims and that clear coat starts to flake and there is this powdered substance there as well

https://youtu.be/dP2BnDSPneI. This is the video I watched where he took apart his broken yong heng compressor. At one point he takes a cover off and you will see the aluminum flaked from the water . I hope you are able to play it .

Edit;
What that video shows is mineral deposits from the well water he is using in it. Plain water cools better than antifreeze. But antifreeze has the needed additives in it to stop most corrosion, and lubricate as well, so it is mixed 50/50 in cars. The additives are needed to prevent boiling and freezing as well.
There are studies around that show distilled water can cause a more rapid removal of aluminum from surfaces exposed to it than plain filtered water. Yet some manufactures recommend it.
You see what high mineral well water does.
I just ran plain tap water, as in our area it is very soft and mineral free, until I had an algae growth problem, then I added some water wetter, some months back, although the verdict on that is still out as It needs a couple more months to be a good test. But it is good for three months anyway. Still it is no longer crystal clear.
So, not knowing all I would probly just use the "Water Wetter" I am using or a watered down version of the 50/50 antifreeze if I was overly concerned about the damage to the aluminum surfaces in the compressor.

I use reverse osmosis water for drinking and cooking. Would if there would be any advantage to using it instead of tap water.

Tap water can be clean or full of minerals and barely potable. It depends on where you live. Any water that is free from minerals and salt would be fine.

Be careful what water you use in your Yong Heng for cooling as water that is very purified like reverse osmosis water, distilled water, and de-ionized water have all or nearly all minerals removed causing the water to become aggressive. When you remove most or all of the total dissolved solids from the water it can begin to eat away at any metals it comes in contact with, the reason for R/O units using all plastic tubing and fittings. I have 40 years of plumbing and water treatment experience behind me so I'm not speaking out my ...... If available to you I would recommend running soft water through your system along with water wetter, in this case you have removed the bulk of the scale causing minerals, but haven't made the water so pure as to cause erosion.

If you choose antifreeze, don't overdo it. Antifreeze is not a very good heat transfer liquid when compared to straight water. It works in a car because the cooling system is designed to make up the difference.

What about engine coolant system conditioner. Water wetter only supposedly helps water cool better but won’t protect pump/aluminum.
I was going to use distilled water. Glad I read this thread. Lots of minerals in our water. Maybe I’ll just catch rain water.

I was wondering just why many compressor manufactures say do not use distilled water. Thank you for the explanation. Knife
