When Air Filtration is Not Enough

Pathogen Inactivation with the Dynamic Germicidal Unit

Why is Pathogen Inactivation Necessary?
Every year, molds, viruses and multi-drug resistant bacteria cost not only millions of dollars, but also human lives.  These airborne pathogens are commonly spread when droplet nuclei in the 1 - 1.5m range are introduced into the air stream through acts such as coughing or sneezing.  These droplets can take considerable time to settle out of the air stream.  The Dynamic Germicidal System (DGS) removes these droplets from the air stream and inactivates them.

Ultraviolet Light has been recognized for years as an acceptable method for pathogen inactivation.  One of its first uses was in the area of water treatment, where slow flowing water made it easy to provide the exposure time necessary to kill pathogens.  Then, UV was applied to the HVAC industry, where it was used primarily to inactivate pathogens on fixed surfaces such as an air conditioning coil. 

Applications Benefiting from Pathogen Inactivation

Hospital isolation wards and infectious disease areas.

Unscreened patient populations in waiting rooms, radiology, emergency rooms.

Doctors offices and waiting rooms.

Dental offices to prevent patient-to patient transmission of aerosols.

Agricultural applications for the extended storage of fruits, meat and vegetables.

Industrial applications where bacterial product contamination is a concern.

Correctional facilities.

Archival storage of printed media.

But air flows much faster than water and this creates a problem when using UV to inactivate airborne pathogens:  To inactivate an organism, it must be close enough to the UV light source and it must remain there long enough to be inactivated. Stand-alone UV bulbs cannot guarantee this will happen.  

Only the Dynamic Germicidal System solves the problems of distance and duration, through its unique patented system, making it the most effective UV system available.

The Dynamic Germicidal System
 
with Ultraviolet Light Pathogen Inactivation?

The Dynamic Germicidal System combines a high efficiency filtration system with a UV lamp only 1.25 cm from the media surface.

Due to the close proximity of the UV light to the translucent media, each organism is exposed to an extremely high intensity light from multiple angles, resulting in a kill ration that free standing UV light systems can't come close to. 

Capture.  DGS utilizes a patented, electronic polarized, low-density media filter.  It is currently used in a wide range of applications, including control of contaminants in clean manufacturing, labs and hospitals, removal of cigarette smoke and odors in the hospitality industry and removal of molds and particulates in general HVAC systems.

  • A unique polarizing technology employing safe 24 volt current.

  • Single pass efficiency of 95% at 1.0m (tested by Canadian Bureau of Infection Control)

  • Near HEPA quality filtration in multiple pass situations due to agglomerating technology

Inactivation.  Once the pathogens are captured on the media, they are inactivated with high intensity ultraviolet (UV) light.  UV has been recognized by the Centers for Disease Control and other organizations as an effective means of inactivating pathogens under proper conditions.  For UV to be effective, it must be able to provide the necessary energy (a function of distance from the bulb, cleanliness of the bulb and nominal intensity of the bulb) and the necessary contact time with the pathogen.  The DGS provides these conditions: the pathogens are captured and held on the low-density media; the media is then constantly scanned at close range by a high-intensity UV bulb that is kept clean by the aerodynamic design of its housing.

  • Unique traversing light allows penetration of low-density media from multiple angles
  • Traversing light allows bulb to be in close proximity to media (1.25cm)
  • Highly polished reflector directs light toward organism and keeps bulb clean
  • Highly resistant organisms can be inactivated due to cumulative effects of intensity
  • Allows a dosage of over 100,000 microwatts/cm2 to any given spot on the media with each pass of the bulb (10x the dose necessary to inactivate Tuberculosis bacteria)
