Air purification through Bipolar Ionization
A range from 100 m 3 / h up to 25,500 m 3 / h
NEW
Bipolar ionization can provide low-ozone air purification for new air handling systems or for retrofit into existing systems .
Johnson Controls deploys bipolar ionization technology to supplement a holistic clean air plan built on proper ventilation , filtration , disinfection , and isolation solutions . Under specific installations conditions tests have shown that bipolar ionization can supplement clean air delivery into a space and contribute to an overall reduction in the risk of the spread of viral infections .
As with all emerging technologies *, Johnson Controls recommends that customers interested in bipolar ionization work together closely to appropriately plan and configure a system to meet the unique needs of each space and application . Johnson Controls believes that ventilation and filtration codes and best practice standards should be implemented regardless of whether bipolar ionization is selected for supplemental air treatment .
How does bipolar ionization work ?
An ion is an atom or molecule with a net electric charge due to the loss or gain of one or more electrons . When outdoor air comes in through the unit , the air molecules are carried over the bipolar ionization tubes .** An energy field converts these molecules into positively and negatively charged ions . These ions then travel into occupied spaces and seek out oppositely charged bad air particles – including dust , mold , odors , volatile organic compounds ( VOCs ), and more . When the particles combine , it forces them to break down and drop out of the breathing space . This process reduces contaminant levels to improve health and wellness .

** All ionizer tubes can run for approximately 17.600 hours before they need to be replaced .

Mechanism for reducing airborne particles
• Ions surround the airborne particle .
• Particles become heavier .
• They drop out of the breathing space .
