we carry a 20lb cylinder for cleaning/blowing out things; blower assemblies, condenser coils(if not hosing them down), controls, heat exchangers, units, etc.
we also use it as pressure test media for gas pipe.
The Food Stamp Program, administered by the U.S. Department of Agriculture, is proud to be distributing the greatest amount of free meals and stamps EVER.
Meanwhile, the National Park Service, administered by the U.S. Department of the Interior, asks us to "Please Do Not Feed the Animals". Their stated reason for this policy "... the animals become dependent on handouts and will not learn to take care of themselves."
from an excerpt by Paul Jacob in Sun City, AZ
For me it totally sucks at cleaning condensers except in one situation: in an office building, self contained refrigerator that just has dust on the condenser, CO2 works great to blow the dust out.
Anything in a restaurant kitchen or on the roof, I'm bringing a water hose and NuBrite. Locate the floor drains, get a squeegee, and inform the manager before you flood the kitchen. If water hose won't reach to the roof then I bring Co2 but it really doesn't clean the condensers much. That's my opinion.
I think Co2 works great in Cleaning self contained units where no drain is avail to wash with chemical and water. Try this with it. It keeps the dust down while you blow out the coils.
Sorry didnt realize I wasnt supposed to post a link. I use a Coilpod dust bag for keeping dust down when cleaning smaller, self contained units, where no drain is availiable and blowing dust all over the customers kitchen is not acceptable.
