    If everybody is so conserned with tank trash why don't you just run the refrigerant through a dryer when you put it back in?

    same here, only virgin back into the system..

    Ok lets say you just pulled a charge and replaced a stopped up dryer that was found to have a major temp drop across it. You vacummed and weighed in a virgin charge.

    Now you start the unit and OH H#LL the orifice header tubes are stopped up to. Would be almost impossible to have diagnosed prior due to the drier restriction. So you recover the charge you just put in.

    After changing the orifice header what you gonna do????

    In this case I will recycle the refrigerant back to the system...But generally speaking if I recover less than 30lb of used refrigerant I tend not to recycle. I prefer to use virgin gas rather than putting back possable contaminated gas back into the system even though the F/D's are replaced.

    Long running Thread

    One company I worked for had the big 1000# tanks with the liquid dip tube. We simply used a 3 or 4 core replaceable shell with valves on the inlet and outlet. It was piped to the base of the tank for liquid recovery push / pull. When it came time to return the refrigerant to the vessel it went through a new set of clean-up cores before it went back in the chiller. If the situation was warranted all the valves were removed and (bite my tongue ) R-123 was circulated through the tank. The top refrigerant level gauge port (float) was removed and a spray header was installed in it's place to spray all down the sides of the tank to the bottom and returned through replaceable cores to a refrigerant pump and kept circulating until the delta "P" across the cores was negligible. As bad as R-123 maybe it is one excellent cleaner. The refrigerant was then pumped into a holding cylinder, the R-123 liquid and vapor was pulled via a recovery system to micron range. The system was charged with dry nitrogen to 10 CFH while all connections were removed. The drum was left with a 5# holding charge of dry nitrogen until the next use, when it was evacuated. Any of the labor cost 5 hours per cylinder was added to the job costing. The also had air compressor tanks with 10' blind flanges 6" from the bottom, welded on the side for reaching in and cleaning. Even with these avail options there were times when you got dirty tanks on the job delivered right in front of the customer. That's always a hard one to explain-GEO
    Once in a while everything falls into place and I am able to move forward, most of the time it just falls all over the place and I can't go anywhere-GEO

    Sooooooo how are you determining whether or not you have the proper oil charge if you throw away all of the old, oil laden refrigerant?

    Your practices are only helping accounts payable in making more money for the company, your not doing any other good at all, period. Just my opinion...

    So lets say you have a 1000ton chiller on R123 and for the sake of argument it has 1500lbs in it . Its purring like a kitten no oil loss no issues . It develops a minor leak at the evap to liquid line flange . The only way to fix it it to pull the charge .
    I can hear the phone call now .
    Hello Mr Customer . I have that repair quote for you chiller it of course includes a totally new refrigerant charge just because were removing it and we at Hack Air only use virgin refrigerant . You quote will be 60 G's .......When can we start ?????????

    I oversee a facility for a Major Manufacturer and if my folks didn't recycle and we reported that level of use, their environmental folks would have a ...

    I'm a little residential, light commercial tech, not a big chiller guy, we are not in the business to loose money, if the cost of refrigerant is less than getting a call back or not getting to the next call, so virgin refrigerant is the way to go. What the office does is none of my business.

    You may want to go to the top of the page and look at the forum this is under. 100, 500, 2000lbs and more are normal charges.

    You may want to slow down and read the quote from graham you quoted!

    Under your self stated beliefs I doubt your phone would be ringing and I an SURE you would not be able to subcontract him.
