BBJ Mold Control for HVAC Systems and Air Ducts® is registered with the EPA for the following applications, flexible ducts fabricated of metal or plastic, unlined sheet metal ducts, air handlers, cooling coils, fan coil units, condensate drain pans, humidifiers, dehumidifiers, registers, grills, diffusers, fans, and fan hous-ings, transfer boxes, turning vanes, return ducts and plenums, and rooftop units.

BBJ Mold Control® also controls organisms that form a biofilm on cooling coils and other working parts of HVAC/R systems that interferes with the heat transfer process causing reduced system efficiency. BBJ Mold Control® also prevents corrosion that is often caused by sulfuric acid secreted by common bacteria. With its exclusive rust and corrosion inhibiting action, systems run more effi-ciently and last longer, improving the overall operational efficiency of the entire system. Consequently, BBJ Mold Control® is effective in extending the useful life of HVAC/R units while increasing overall energy efficiency by keeping fins and coils cleaner.

BBJ Mold Control for HVAC Systems and Air Ducts ® controls and inhibits the growth of microorganisms – such as gram positive and gram negative bacteria, , and mold – that form a biofilm on cooling coils and other working parts of HVAC/R systems and Air Ducts. A biofilm on HVAC/R coils causes increased operating costs as it interferes with the heat transfer process. Treatment of the coils with BBJ Mold Control, with its exclusive rust and corrosion inhibiting action, can make systems run more efficiently and last longer. Furthermore, HVAC sys-tems spread these harmful contaminants – which may cause odors, damage sur-faces and secrete toxic byproducts – to living and working areas. BBJ Mold Con-trol controls contaminants that often cause poor Indoor Air Quality (“IAQ”) and "sick building syndrome" at the source – the HVAC system. It also prevents damage caused by plugged drains by eliminating slime deposits. And it makes system cleaning easier and faster.
