For the refrigerant recovery guys (FreonJoe, etc.), is there a R-18 refrigerant?? I can't seem to find one listed anywhere. The refrigerant that needs to be recovered states that this is what it has.
For those that haven't read my introduction yet, yes, I am EPA certified to recover refrigerant.

If there is such a thing you will need an empty (tank) to put it in so it won't be cross contaminated and a reclaimer might buy it.

I know there is a new refrigerant that can't be reused and aparently you can just let it spary out into the air. We had a new A/C unit put in and the guy just opened the valve and let the refrigrant spray out. When he refilled the unit with new refrigerant the box said nonreusable. I don't know much about this, I'm just saying what I saw and read.
This is a list of the most common refrigerants in use. That one isn't on the list, and if it isn't a 400 series refrigerant, it probably is not a blend. I would be curious to see what you find out!

The new freon last 3-5 years is 410 R 22 is the freon of most H V A C UNITS FROM 1995- 2010 or so , 134 is used in most smaller appliances fridges, vending machines I am not familiar with R -18 though.

Can you get a pic of the label that says it is the R-18.
Curious about this

Bpatnoe,
I'll try. I don't know if I'm allowed to post pictures yet or not.

I've never heard of R-18. Are you sure you read the label correctly? If so, many of us, including myself, would like to know more about what you're trying to service.
From what very little, and possibly inaccurate information I could find, was that R-18 might be used as a refrigerant for cryogenic processes.
Found this, What is cryogenic refrigerant 2 slides of information, again I don't know if it's accurate, but it mentions salt water progressing through freon to become r18.

Admin,
The unit is a Sears Kenmore Coldspot refrigerator / freezer. I will post a photo of the tag if I am allowed to and can figure out how. At this time, I am consider my options with this unit. I could recover the R-18 and hope that the AirGas dealer that I deal with will purchase it. I also have other options available thru utility company incentives.
Mthomasdev, Sears stopped using the Coldspot label in the 70's I believe. Your system is a R-12 system. Probably has a pound or so in it.

Joe,
Thank you. I actually evacuated a different Kenmore Coldspot today. This had 20 ounces of R-12 according to the tag. The compressor was not working. I was able to pull the required vacuum and recovered 16 ounces. The other Coldspot (originally posted about) that is still in the garage clearly says 6.8 ounces R-18. I tried to attach a photo, but it is a little difficult to read.

Good old Simpsons Sears. Leave it to the Canadians to be different, eh? Can you get a better shot of the tag? Monday I will dig through my old Sears training manuals and see what they say.

Is this from Canada?
It was built by Whirlpool (the 106 in the model number) for the Canadian market in 1969 (xxx.6x9xxxx).

Thanks Joe. I'll post a better picture tomorrow. Can't send a picture from my phone tonight, no cell service at the house. I did look again. It is a Simpson Sears and has 12 ounces, not 6.8. The 6.8 is actually the amperage.
