Especially the ones that are tied in to shut down elevators.

My sales rep from United talked me into trying a can of the Viper coil cleaner and now I won't use anything else as far as chemicals go. I hate using chemcials but this stuff has no odor and won't burn your skin. Really does a great job of cleaning.

Short bursts of co2 will do the trick.

Not sure what they put on them but it doesn't foam up like it supposed to. That cleaner reacts with aluminum doesn't it? And that's what makes it foam up? That **** will make you cough your head off too.

Yeah the Viper cuts through the grease and has no smell to it

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

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!

cleaning condensers

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

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 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

watch out for smoke detectors that are sensitive to dust

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.

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.

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.
