I've got an Americold compressor I've salvaged from my father's old dehumidifier he gave to me. The information about the compressor is in the pictures below for identification, etc. I can't find anything concerning Americold compressors online -- looks to me like the company went belly-up and didn't leave a history behind them.

The dehumidifier has a sticker on it that says it runs 6.25 ounces of R22, and the system is 7.3 amps. It also states 40 pints/24 hours for "dehumidification." It is designed for 400 psi high and 150 low. Anyways here are the pics!

I also need help identifying this oil. I'm going to be charging this new phase system with propane but I'd like to keep the original type of oil unless it's too expensive. Here's a pic of the color/amt of oil ... ruler to show scale (amount).

Thanks for your help!
 
I just noticed that the oil in the picture looks a little bit darker than it does in person. Also it's not brown at all (though the picture makes it look brown) just plain yellow.
 
People @ Xtremesystems.org said it was a little over 1hp compressor, so that mystery is now solved. However, I still need to know what oil to buy. They recommended Mineral Oil but is it just normal mineral oil you can buy @ a pharmacy or is it something special?
 
I found the formula it is 1 hp = 745.699872 Watts
I am sorry about my spelling.
3.9A x 115V = 448.5 watts / 745 = 0.60 HP
7.3 x 120 = 876 / 745 = 1.03 HP it is probly rated 1HP
 
motor is 1hp as wrdzal said. The problem is if it is old enough efficiency is no where as good as newer compressor. You can expect maybe comparible result to 3/4hp to 1/2 hp compressor. Which isn't bad thing. You need to get refrigeration quality mineral oil from local refrigeration store or e-bay, etc. Just don't pour the oil in till you are about to braze the unit shut. Also looking at the color, I would suggest filling it once and draining again might not be bad idea to make sure compressor is extra clean. Good luck :) Oh... I am in XS too btw been to sick to progress on my projects recently.
 
wich oil you would use depends on the refegerant that your going to be using...
POE for the new blends.. mineral oil for the older stuff just the basics of it..
are you planning a water chiller or a direct die?

dose POE have lower gell temp point?

the second link gives the temperature application of the oil type/refigerant but it is a little more complicated then just the lower temp. point of the oil.. POE does have a lower viscosity if that means anything to ya..
I did miss Alkyl-Benzene or A-B oil as one of the alternitives.. but most of what I read says that POE performs a little better (doesn't atract moisture as much as A-B) so if POE is listed on the cart with A-B I would use POE.. thats just me though.. :)
 
I'm planning direct die. Looking around locally for some good mineral oil without much luck so far. Time to get out the phone book and start calling up HVAC places.
 
Did you mention what refegerant you were planing on chargeing the system with?
have you desided yet?
If so do tell. :)
 
propane R290 is compatiable with any refigerant oil so the mineral oil plan sounds fine..

Wrong... order of moisture absorption from low to very high.
Mineral < Alkyl Benzene < POE. You feel the oil up when you are about to braze or even after brazing in my case since I have specific pump from Yellowjacket. If it is brand new compressor I open it up at the last minute for brazing than vacuum it even before leak testing to reduce any moisture absorbption.
 
yes vacuming the system corectly removes moisture..
the information on wich oil has a tendency to atract more moisture was just what Ive read on the web.. if it wrong then thanks for the info :) , and I appoligize for the misinformation :( ..
