My Yong Heng is now well over 2 years old. Shooting today, I got my Great White down to 3600 and decided to top off with that compressor. I usually use ice in a 2 gallon reservoir with the stock water pump and an external fan blowing on the heads but I was already outside without ice so decided to run it that way. 72 degrees here this evening. Just above 4000 the indicated temperature had reached 63. I went inside and brought out a 10 cup bowl of ice cubes. Temperature was just over 64 at 4100 when I returned. Added the ice and about a minute and a half later the temperature was 54.8 and it increased to 55.2 when it had reached 4400. I can't say that these things will last longer running at that cooler temperature or that ice in a smaller reservoir is better than a larger volume of water. Don't know for sure. I can say without question that the ice makes a major difference in temperature with the smaller volume of water.
Yong Heng Top Off Today

Good info. Thanks I'm looking for a compressor that will fill my tanks. Just gathering info

Yup when you use a smaller reservoir or top off a large tank ice is definitely the way to go with a Yong Heng. I used ice for a couple of years, to keep things cool with a 2.5 gal reservoir for 15 to 20 minute run times, until I did the radiator mod.
Mine will blow out the burst disc if I take it over 4200psi too often so I just don't do that any more.
Great little compressors for what they are.

I've followed your setup and it is certainly nice. I had never blown a burst disc-until today. I hate to admit this but I started the compressor, closed the bleed valve, and clean forgot to open the tank valve. Burst disc blew, protecting everything as designed. I had replacements on hand so a few minutes and it was running again. As has been said but cannot be said enough, be careful and pay attention around these things.

My Yong Heng is 3 years old and I have used lots of ice in my 5 gal bucket from day 1. My temps never get over 45C when filling my three SCBA's from 3000 psi to 4200 psi. The only part that I have had to change in three years is the original water pump as it died after the first use. Hope I didn't jinx myself with this post.

Agree. It is hard to say that the cooler temps will make them last longer. You either believe it will or believe it won't. I believe it will. But it seems impossible to argue the point that, for any given coolant volume, added ice will create lower operating temps. And the smaller the volume the more ice lowers temps. Like many things, all relative.
