Well it would be for benching only.

On AMD right now, so would be wanting to use it on a AM3 quad although currently it is a dual core.

I will ask him what his experience was with it.

unloaded temps give an idea of how it was charged and with what gasses, and that it even works.

Example if it's unloaded temps are -51c then its ok to procede with checking it out. But if unloaded temps are -20c then I would say its charged with BBQ gas and stay away from it :)

Basiclly it's just to give an idea of the state of the unit, does it work, is it getting to temps to be expected, has any gas leaked out. Thank kind of stuff.

As far as I know R22 is not used anymore by any builders for SS Phase units.

I would ask for some pics with a thermo meter hooked up to it also.

Do you have any idea who built this ?

It's not often you see Rotary Compressers used for SS units these days.

good call, good call. :D

Buckeye you are pretty knowledgeable about phase. Ever try making one?

Not yet. But I do plan on it.

The kid said it is running "Something better than R22"

Buying a Phase unit is not really an option for me, this was something I could trade for, hence why I was even considering it.

There are too many things the kid does not know about hte unit, which is why I started the thread, was hoping that maybe, people could tell by looking at it or tellingme simple things to ask him.

When he comes online tonight I will ask him about the unloaded temps.

Is not knowing what gas is in it a bad thing?
Did some reading on refridgerants today, and it seems you have to change the oil based on the gas used. If I was to get it, is regassing simple enough to do?

Also about hte 1/2HP rotary, are they not used because they are bad?

No they are not bad. For a long time people built Phase units to sit under the main computer making Rotarys to big for that. I see that blue condenser and that I believe came from Chilly back in his days, so I suspect it's what we call a Chilly1 type of SS Phase, usually used for Dual Core CPU's.

But if it has been regased or modded it could be much better, thats whay I asked about unloaded temps.

Regasing a unit is no easy task. You cannot simpy vent the gas out as that is illegal and the gas must be recovered. It then must be vaccumed down to remove all traces of the gas that was in it before. Then regased and tuned to the new load and gas.

Different compressers use different gases and these require different oils inside the compresser depending on teh new gas used. That is also not and an easy thing to do, change the gas the unit was spec'd for and replacing the oil to match the gas.

Phase builders do that stuff all the time and have all the tools needed to do so, if you don't it's best not to try.

ocgmj 06-23-2009 01:12 PM

Also the tool for this type of work are not cheap one bit. Just some things to keep in mind if you plan on trying to regas on your own. You could send the unit to one the guys Buckeye and myself mention earlier, if they are up to it.
