    Need help with new foaming coil cleaning machine. Ultrosonic?

    The machine part would be the frequency generator. Other part would be a thin viscosity cleaner excited by (the sound/frequency) generator instantly turning the cleaning fluid into foam. The penetrating cleaner fluid could generate foam from deep in core of coil pushing the dirt out. No need for a harsh reaction to the aluminum metal fins for foam to form and push out the dirt.

    I only need help with the formula for the fluid cleaner and the frequency machine.

    Any Thoughts ? Too futuristic for man kind or what ?

    Easy foam cleaner! How about solution of vinegar and coil cleaner applied liberally to coil and then rinse with a baking soda solution or vice versa?

    Is it immersing or spraying?

    Spraying, immersing would be better but more work

    I have two vague ideas. A cleaner to be excited by a device, sound/tone/frequency generator turns the saturated cleaner into boat loads of foam. Other a 2 part cleaner makes a chemical reaction between the chemicals and makes the foam, not a reaction to aluminum fin's

    I had an evaporator with poor airflow icing up and all. Coil fin's looked in good shape, I cleaned it in place with small weak pressure washer, no dice. Then I pulled it and cleaned it at a car wash. When I thought it had enough I then tried some foaming type cleaner that I usually avoid and the foaming action started pushing more dirt out. I blew it out again still at the car wash, reinstalled it and still no dice.

    I then replaced the coil at the cost of the air handler and success. The home owner was happy with it. Her coil had fin's stamped into the fins, a thousand little slots. Slots in every fin between the tubes. I cut the coil open and found oxidized aluminum and dirt clogging those little stamped slots. Now I look for those slots before I clean a coil and tell them it should help. Those slots are a screwed up design.


    (I only need help with the formula for the fluid cleaner and the frequency machine.) I was trying to make a funny here, but I would like to see it happen. I for one would like a better coil clean in place without removal.

    So you picture the ultrasound doing it's thing after the coil is sprayed or as it's being sprayed? What about a two part system, like the action you get with mentos and diet coke. Did you keep that coil as a test subject? I might have your answer, but I'll help you think on it.

    A company actually was trying to market an ultra-sonic Coil cleaner back in the 80's. It had an ultra-sonic clamp that attached to the coil, and a small power washer nozzle also pulsed. They advertised it need no cleaning solution, just water. They gave demonstrations, and put a tiny bit of dish soap in the water, just to make the ultra-sonic more visible. Very impressed with the amount of dirt that came out of some old Coils. It was at a Trade show, and that was the first and last time I saw this. I always wondered which chemical company bought them out.
