Is R-11 Flush worth the time?

[Tommy1010]

Have a Carrier package, 2 stage ,R22 water cooled system.

Water breach in brazed plate condenser flooded entire stage. Compressor sounded like a water cooler when I removed it.

Removed and changed condenser, compressor, Drier, Txv and re-made liquid line. Pushed what i can from evap wit Nitro.

I have this R-11 Flush that I been hesitant on using. Is it worth the time, or will MORE nitro and triple-triple evac do the job?

I would go for it,


Rx11-flush is a unique solvent that has been engineered
for flushing refrigeration and air conditioning systems. Its
patented HFC based solvent formulation is powerful enough
to flush away sludge, carbon residue, oils, acids, water and
other particulate. This makes it ideal for system flushing
after burnouts, retrofits and for flushing line sets for R-410A
conversions. It is non-toxic, non-flammable and is non-ozone
depleting

i use rx11 every time i change from 22 to 410a. if i cant change lineset.

for the extra 8 bux.....why not?

also appears to make evac time shorter

I saw a pretty cool demo at our shop by the nu calgon guy where he removed some skunky looking oil from the inside of some tubing. Now, granted it was a demo, but the product seemed to clean a whole lot better then the nitro purge he did prier to the flush.

it works good if you flushing from the top of the lines and having it blow out at the bottom. pinch your lines shut to create a restriction where its blowing out. i also use lots of nitrogen and make sure there is no more oil coming out.

I was readin bout the nitro involvement. Do they simply mean do the nitro AFTER? One site made it seem like nitro was to be included in the flushing..

Also FYI...I plan on running it from distributor (evap inlet) cuz i havent put the new TXV in yet..Nor have I piped/ brazed in the new compressor yet either. Everything is ready, but I need to verify that THE EVAP is dry, before I risk damaging new parts and wasted and repeated time.

So just picture the system. run R-11 thru TXV Distributor..YES AT THE TOP....and exit thru restricted suction line b4 compressor. at the bottom
Im only worried bout EVAP being cleaned out thoroughly. Everything else, gravity, heat, nitrogen and vacuum will handle.

u add some r-11 to the system, flush it with alot of nitro, use the r-11 again, flush it with nitro some more, and continue. i use a whole bottle per system but thats me.

if your only worried about the evap coil, then braze some stubs onto the ports and only flush the coil. also flip that puppy upside down to try and get as much oil out. you should be good to go after that.

are you doing a refrigerant conversion?
