Cleaning of Vessels of all sizes is critical for the efficiency of heat transfer. This applies to small vessels like Heat Exchangers, Chillers or larger vessels like boilers. Brushes are the most common and economical way to clean these units. Efficiency in Chillers and other vessels drops dramatically as deposits build up.
With the use of Brushes and a Tube Cleaner, regular maintenance is straight forward and will pay off in increased efficiency. The percentages of decreased thermal transfer drops quickly even with a small amount of deposit. A coating as thin as .0045 can drop chiller tube efficiency by as much as 44%. The fact is, that the cleanliness of heat transfer tubes is the single biggest determining factor for chiller efficiency.
