The test results as provided by a NATA certified testing agency have identified the lowest detectable levels of legionella which is <10 CFU/ml, and the TBC has consistently remained at less than 103. This is an excellent result for cooling towers which are using chemicals, but is an exceptional result from cooling towers which are using no biocide or algaecide chemicals. When the condenser end covers were removed for their seasonal inspections and tube cleaning, every tube was observed to be completely clean and shining like a gun barrel.
