### What is the cleanliness factor in a heat exchanger? - Quora

Aug 09, 2019· If the tubes are expected to foul faster, the condenser will have a cleanliness factor of say 85%, meaning the tubes can be fouled up by about 15% and still meet what was promised. Most condensers built with slower-to-foul tubes are built to a 90% cleanliness design factor. so a 10% fouling will still deliver rated performance.
