AIR DISINFECTION – NEEDLEPOINT BIPOLAR IONIZATION

This technology generates charged atoms or molecules called “ions”. These ions cause small particles to be either positively or negatively charged and create a magnetic effect. Opposite charged particles attach to one another, gain mass and surface area. Larger particles can be filtered in the air handling unit. When ions combine on the surface of the pathogen, they remove hydrogen form the pathogen and inactivate the virus . • The older technology called “Corona discharge ionization system” generates Ozone as a byproduct. Needlepoint system can limit the supplied power and eliminate Ozone generation. • This system is flexible and can be installed within units, ducts, ductless units etc. • Based on airflow rate and coverage area they come in different shapes. • The devices available in the market are self cleaning and maintenance free.
