Greffen UV-C Germicidal Lamps:
Greffen offers a wide range of UV-C Germicidal lamp technologies including upper-air units as well as in-duct UV-C lighting. All of the technology offered by Greffen is the same 253.7 nm technology that has been well proven for years to sterilize hospital operating rooms.
Greffen’s Upper-Air wall mounted fixtures offer a proven solution that will kill viruses and pathogens as they rise in the room from both ventilation as well as convection of the natural heat plumes from the occupants in the room. These units are mounted at approximately seven feet in the room and offer unique pathogen killing performance while totally protecting the safety of the inhabitants.
In-Duct UV-C solutions are unique in their ability to kill viruses in one-half of a second as they pass by germicidal lights. While UV-C’s effect on COVID-19 has not been studied yet, there have been numerous studies that show that 253.7nm UV-C solutions are extremely effective in killing varieties of coronaviruses such as SARS and MERS. Based on the information available from authorities, coronaviruses can be transmitted via both air and direct contact. It can be assumed that the virus can be ingested into the return air-plenum and be moved throughout the organization’s air handling units and the building’s duct work.
Energy Savings: Greffen’s UV-C solutions also offer tremendous energy savings by cost-effectively eliminating 90% or more of the organic growth to significantly improve airflow and heat-exchange efficiency. This dramatically reduces the pressure needed for the fan to produce the required CFMs per the air handling unit’s design specifications. This continuous coil cleaning assists in keeping the entire HVAC in balance produces a tremendous ROI of often under two years.
