Do I really need "better" cooling with my Yong Heng compressor?

I see a lot of videos and articles where people are upgrading their cooling on their compressor. Using Ice Cubes in the water... using anti freeze... using a fan to clamp to the top of the compressor and blow right on the head... using huge 30qt-50qt coolers full of water/coolant.... do we all really need this or want to do this? 

I understand some people are filling multiple bottles and want to do it in a short period of time and cooling probably really helps with that. 

But what about us more "average" users only trying to fill a single bottle? Do I really need better cooling then a small bucket of distilled water for filling a single bottle 30cu ft. from lets say 2500 psi to 4500 psi? I cant imagine it would take all that long to fill 1 bottle maybe 15min but I have no idea, that's just a guess.

I don't want to burn my compressor up either, but do I really need all these other cooling options necessary for a 1 bottle refill? I can understand something simple like a little clamp on fan to blow on the head of the compressor, that is a $10 cost and easy enough to do. 

Is there a duty cycle like a 20 min run time and then 20 min off time for these yong heng compressors? 


 
Be carful. Max fill pressure. Is 4250. A fan and a few ice cubes will surely extend the life of unit. Filling to 4500 constantly will result in short life span. 15 minute run time and let her cool down.

Thank you, 15min it is then. I will for sure do the fan. Ice cubes I guess I can buy a new ice tray and keep it special for distilled water if the ice cubes really do help. I am guessing current air temp makes a difference also? Probably easier to keep cool on a 50deg day vs a 100deg day. 

What about filling in the winter? My garage can easily be below freezing. Will running the compressor in below freezing cold damage or hurt anything or will it just help with the cooling of the unit? Or should I bring the unit inside the house to fill at a 70deg F. temp?

Antifreeze does nothing for cooling and can cause corrosion if the wrong formula is used. Best to not use antifreeze. If your unit will be exposed to freezing temperatures, blow the lines clear of water with a burst of compressed air.

Best to keep the compressor warmer than freezing. Keep it inside the house until you need to run it. Don't let the pump get pump cold soaked. Lubrication will not be good if the oil is thick.

I think it is interesting that the general consensus seems to be to run a compressor cold and to keep it cold. Are the clearances in these units that tight?

Allen, its all about controlling the heat. Run to long and get to hot, this is what happen. Orings cooked.

Do you run your car engine hard when it is below operating temps?? I bet not. Oil does not flow right when it is too cold. Friction is increased when metals are very cold. Metal parts will be more brittle when frozen. Heat differential causes stress risers. Having a frozen chunk of metal get hot on one end while it's being slammed back and forth under high pressure is not a good mechanical situation.

But.... Go for it and let us know how long it lasts.

IMO, you can't beat a bucket of water. If you are worried about the water getting too hot or corrosion, use a bigger bucket and drain the unit after use. None of the homemade contraptions with radiators and fans will do a better job than a five-gallon bucket of water. Heat is not a problem. Exessive heat is and so is feeding freezing coolant into the jacket of a hot cylinder.

View attachment Dealer advice.1627395318.txt This is some advice from a dealer here in Australia that sells YH pumps and covers the units he sells with his own warranty. He refers to people who use ice as "clowns" and claims to have sold more than 250 units with only one coming back with warranty issues for what he describes as clown damage.

No offense but one of the things i hear people say often is use common sense. Common sense is not natural to some and thats why people look for answers. 

I work with new employees everyday and what you and I think is common sense apparently is not that common at all. Sometimes it is just as simple as not knowing all the facts. And those facts are not all that simple or easy to be aware of.

Just because it was on YouTube or the internet does not mean it is correct. There is a lot of misinformation out there and it would be nice that the correct information is stated on such a fine forum as this one is. Thats why I ask certain questions. Not necessarily because I think some people are doing things wrong or I don't know the answer, but because I want to know the thought process and see if it is correct. It also so other can understand why we do the things we do, often times there are better ways to do things that we would never have thought or try or do.

Under no circumstance will you be running the compressor "cold" unless it has been sitting outside in freezing temps, then I would recommend warming it up.

What I've found (thru trial and error) is its best to keep operating temp below 60C. I prefer 50-55. I also try not to run mine more than 10 min. At a time. Never start under load or stop under load.

I use a fan directed at it and 2 bucket method. One bucket cold water from garden hose and the warm water from the compressor goes to another bucket that gets emptied out to my yard. I found this method just as effective if not more so than adding ice. It usually takes about 8-10 minutes to get to 55c degrees and that’s usually enough to get me to 4000-4200 psi. I don’t let my bottle go below 3000psi and don’t usually fill it much pass 4000 psi.

Citing what JimNM said,

what do you think the lower threshold of temperature should be for these units. And what temp should intake water be going into the compressor?
