OVERVIEWHealthcare Associated Infections (HAIs), or Nosocomial infections, are one of the leading causes of death in the United States of America more than Breast Cancer, AIDS, and Auto Accidents combined.According to the American CDC (Centers for Disease Control and Prevention), one of every 25 patients contracts an infection in the hospital causing more than 75,000 deaths each year in the US.205 Americans die from Hospital-Acquired Infections each day.HAI cost more than $10 billion annually in the US.

Airborne transmission is one of the environmental routes of Nosocomial infections in hospitals such as Infl uenza, SARS, Measles, Tuberculosis and many incidents and outbreaks of nosocomial infection have been linked to malfunctions and contamination of the ventilation systems in Hospitals.International standards recommend UVC IN-Duct Air purifi cation in conjunction with fi ltration in HVAC to reduce the risk for the spread of environmental especially fungi and bacteria.

BEFORE

AFTER

OBJECTIVEDestroy up to 99.9% of contagious airborne biological contaminants (viruses, bacteria, spores) in the in-duct airstream that circulate through the building’s HVAC system without increasing the pressure drop.

UVC ultraviolet light produces a specifi c wavelength of 253.7 nanometers (commonly called 254 nm) or “Germicidal” because they alter or fl ip a microorganism’s DNA molecule to form dimers making it incapable of reproducing under the condition to deliver the required microwatt dosage of UV energy.

TECHNOLOGY

OPERATIONEach sterilization module is designed according to the existing or projected HVAC duct and manufactured with a refl ective material such as aluminum, galvanized steel or stainless steel to increase irradiations from all directions.Sizing calculations will consider the microorganisms to eliminate and inactivation rate to achieve, air velocity, duct size to determine the number of UVC emitters and individual output.The UVC lamps will be positioned in longitudinal

direction (airstream direction) on the inner walls of the duct to maximize exposure time and increase UVC irradiations received by the contaminants.The UVC emitters will be mounted on the inner walls of the duct to minimize the cooling down effect which is greater if placed in the middle of the duct and affects the UVC emission performance.The UVC emitters will be mounted above one another to maximize irradiation of microorganisms from all directions via wall refl ection.
