Has anybody got a good trick for blowing out condensers , espeacially on self contained units, where the dust is contained instead of blowing all over the kitchen or where ever you are? I use co2 and a wet towel over the back of the condenser but still it doesnt do an adequate job of containg the dust. A vacuume don't work either.Who out there has a good way. Also thanks to all for the help on the freezer. we are gaining, got er down and holding 8'.

Well, at home I use a small bottle brush. Then blow the heck out of it with my air compresser and tell the wife to cover anything she does'nt want covered in dust
PS, I tried a vacuum cleaner once,, but it took more than 5 mins, so I blew that sucker out!

The pharmacies I do, I use the brush, then nitro with a vacuum trying to suck the crap out of the air.
I didn't say it worked the best...but that's what I do.

Use a damp rag behind the condenser, then the dust will mostly cling to it.

If you don't know, then don't do. If you don't know and still do, then be prepared to pay someone else a lot to undo what you did and then do it right.
If you do know, then do. But do it right. Otherwise, you may not be doing it long.

Take a shop vac in and set the hose near the compressor and fan motor. Cover the whole unit, except for the condenser inlet, with a large wet towel or cotton tarp. Turn on the shop vac and blow out the condenser with 150 lb. nitrogen pressure.

I'm going with that.

I've had a few like that in some restaurants. I just unplug them, roll them over to a floor drain and wash them out with my Coil-Jet cleaning machine. No muss, no fuss and it's nice and clean.

we use filter media on our self contained units that we service and change then once a month and also blow the out the condensers with co2.
I love the smell of phosgene first thing in the morning:

ditto on the media....a lifesaver 9 times outta 10
I use cans of coil cleaner/degreaser. Foams real good, pulls grease off, washes clean with water hose.

Water and a wet vac, or CO2 and a wet towel. Tell owner not to wait until they are plugged if they do not want mess.

watch out for smoke detectors that are sensitive to dust

i keep a roll of 24" x 12' x 1/4" foam filter media on my truck for these applications that i can custom cut .. some dust makes it way thru but it is way easier to remove a matted filter & replace it then it is to have to go thru the other messy process .. + im lazy

Filter media is nice, but in some cases, impractical. The foaming evap cleaners are nice, but expensive if you have a lot of self contained units. Wet rags, water sprayers and just letting the dust blow. I've tried them all.
The best solution that I have found so far is a sprayer for my co2 or nitrogen bottle that has a venturi for chemical pick-up. Plunk the hose in a bucket of water and hose away. That nearly eliminates dust. Of course, there is the issue of cleaning up the mess that runs out of the bottom, but in most supermarket applications, that's easier than explaining a mushroom cloud of dust in the deli or bakery dept.
As an extra benefit, you can get enough flushing and washing action out of this to clean small single condensing units, up to 7 hp or so, using a chemical cleaner in a pump sprayer plus the water.

Nice description. I like the idea of nuking the deli dept. (just kidding.. umm maybe not)
Where did you get the venturi device or did you adapt a hose sprayer?

I have used a product called blowout it is pretty expensive works good but has apretty bad smell.

I found the one that I currently use at harbor freight tools. I have seen them other places.
I tried making one, but didn't get the restriction right to create a venturi and created a mess when the co2 flow went into the bucket rather than into the condenser. WHOOPS!

Sorry, but I was using my BB earlier, here is a link to what I am talking about.
