This is a Flow-Tech marketing add mixing and miss-stating data with regard to ASHRAE research data - and actually using ASHRAE to support a product and technology that is w/o science-based data as reported. 1. The ​American ​Society of ​Heating, ​Refrigerating ​and Air-​Conditioning ​Engineers (ASHRAE) does NOT have a "protocol for controlling sessile bacteria, or biofilm" as stated above, much less does ASHRAE recognize or endorse products to "meet and pass" such. 2. The ASHRAE research project Flow-Tech references above (that Flow-Tech participated in) was ASHRAE Project Number 1361-RP-1361: Biological Control in Cooling Water Systems Using Non-Chemical Treatment Devices (2009) -- and NONE of the 5 non-chemical devices tested in the study showed biological growth control under the conditions of the testing in the pilot scale cooling tower systems. 3. The ASHRAE research project (cited above) was a cooling tower research project and not a building domestic water system project (as, confusingly, presented above). I do not like to present such strong rebuttal verbiage in an open media forum, but I was Chair of the ASHRAE Technical Committee (TC3.6, Water Treatment) that sponsored the ASHRAE Research Project 1361-RP. This article mixes cooling tower water with domestic potable water (Legionella) control, completely "stretches" research data beyond the science, and is first and foremost a marketing add verses any meaningful, certainly truthful, evidence-based science article. (IMHO)
