How to clean a microchannel coil

Many customers ask us what procedure they should follow to wash and clean microchannel condensers. Their main concern is that, as they see how light and thin these condensers are, they are afraid they can get damaged with high pressure water or by brushing them. Not at all! MICROCHANNEL CONDENSERS ARE EXTREMELY ROBUST. And as an image is worth more than one thousand words… a video is worth more than one million words…

This cleaning was done with a 120 bar Karcher machine


As you can see in the video, one of the great advantages of microchannel technology is that, because being so thin, water goes very easily through the coil, cleaning every little corner between fins.

General recommendations for cleanning:

  1. You can use high pressure air or water, up to 120 bars (hot or cold)
  2. You can also use a soft brush to remove debris or persistent dirt
  3. You can use some NEUTRAL soap or detergent. VERY IMPORTANT: it has to be neutral. The reason is extreme pH chemicals can affect the natural protective aluminum oxide layer. SEE OUR PREVIOUS BLOG ARTICLE:
