ID Refrigerant in a recovery tank?

[Mechanical302]

Hi guys. I have a refrigerant recovery tank that no one knows what type of refrigerant it has in it. I was wondering if you guys know a method of knowing what type of refrigerant is in a tank? Thanks!

refrigerant recovery services carry a little testing device and can do it for a charge.

Hopefully no one mixed different refrigerants in that tank.

Providing that the refrigerant has no non-condensibles and is not a mix of different refrigerants a TP chart and a standing pressure check should tell you the type.

Store the recovery tank in a controlled environment for 24 hrs with an accurate thermometer. Put your gauges on and check the pressure/temp against a PT chart. This will work only if their aren't any non-condensables or contaminants present.

Yeah man! i know its expensive wen someone mixes diferent refrigerants in one tank.

I have a question and don't want to hijack this thread but is there any place I can take my recovery tanks and swap them out for free? Johnstone charges me like $45 and the refer I give them is in good condition

What about going to the recyclers themselves and cut out the middleman?

There are places that buy clean refrigerant. They also have testers to tell you whats in the tank, and how pure it is. R22 for example is slightly more than a buck a pound to the positive, ie they pay you. price depends on purity.

Sent in a 1000lb cylinder last month, just over 900lb at 99% plus purity got us $2.00 per pound and they covered all shipping cost.:grin2:

I have a tank like this in the back of my shop. What I got for hiring a helper that got over excited. Good kid just dosent understand english. As for keeping mine straight I mark my tanks with a permanent marker.

I get quite a bit of R22 but the largest tank I have is 50lb, As mentioned before they want 1000lb before they want to buy it.

There are several places that will take pure or close to pure (97%) for free, localy we have a Corken steel in Cincinnati that will do that. I dont like dealing with them much because the only guy that KNOWS what is going on with the recovery is also a service guy. They have lost 2 of my bottles and refused to replace them,,,, yadda yadda yadda.

On the mixed stuff first dont,,,,, second do not but third if you do mix a bottle call around I was priced as high as 5.50 a lb and a 50.00 recovery fee but am finally getting rid of it for 2.50 a lb and 20.00 recovery fee. It is a PITA and I dont recomend it. with 16 piunds in the bottle that sets me back 60.00 when I could have gotten rid of for free or got paid for it. Ya it makes me grumpy LOL
