Operating Room - UVC lights provide infection control, green benefits

Muskogee Community Hospital (Muskogee, OK) is using germicidal UVC (ultraviolet C) Emitters™ from Steril-Aire as part of an innovative infection control measure. The devices were installed in the air handling units and in custom-designed, ceilingmounted units in the surgical and procedural suites, marking the first time a hospital has used UVC technology in this way. Steril-Aire devices ...

UVC approach stops mold, enhances IAQ for medical firm

Though mold problems in buildings are often associated with humid, tropical climates, mold can occur virtually anywhere — even in our most northern states. At Medicine Lake Properties, a commercial building in Plymouth, MN, mold-related IAQ issues were causing problems in one of the office suites. The 3,500-sq-ft suite is leased to a medical company that uses the space for administrative ...

UVC keeps indoor air, a/c coils clean at College of the Sequoias

At College of the Sequoias (COS), a California community college in Visalia, CA, indoor air quality is a high priority. “We have not had IAQ complaints, so when we discovered naturally occurring mold growth in the air conditioning coils, we decided to treat it proactively — before mold-related allergens circulated from the HVAC systems into the occupied space,” stated Eric ...

Hyperion case study - UVC lights enhance air quality

Located at the center of the Hyperion Wastewater Treatment Plant in Los Angeles, the Pregerson Building was experiencing indoor air quality (IAQ) problems. Built in 2002 to house nearly 400 city employees, the facility rapidly became the source of complaints about poor IAQ and odors. An engineered solution that incorporates both an odor control unit and supplemental ultraviolet- C (UVC) lights in ...

Spectral distribution of uv light during aging of medium pressure UV lamps

As part of a project to validate a UV reactor for disinfection of drinking water, the germicidal output of four medium pressure lamps housed in a continuously operating reactor was followed as a function of time. Spectra were measured monthly and were used in conjunction with radiometer readings to calculate germicidal fluence rates (using DNA absorbance weighting) at the radiometer sensor ...

Lethal light

From radio signals to gamma waves, the electromagnetic spectrum offers considerable potential to prepare and preserve food products. Knowing precisely which wavelength in the spectrum to apply to a particular need is only the first step, however: scientists and engineers also need to fabricate systems that can withstand the rigors of an industrial environment. The application of UVC, short-wave ...

Types of UV Light for Different Applications

Types of UV Light for Different Applications Ultraviolet (UV) radiation was discovered in 1801 when the German physicist Johann Wilhelm Ritter observed that invisible rays just beyond the violet end of the visible spectrum darkened silver chloride-soaked paper more quickly than violet light itself. He called them "oxidizing rays" to emphasize chemical reactivity and to ...

Use of CFD Modelling to Optimise the Design of Upper-room UVGI Disinfection Systems for Ventilated Rooms

AbstractThe installation of upper-room ultraviolet germicidal irradiation (UVGI) devices in ventilated rooms has the potential to reduce transmission of infections by an airborne route. However, the performance of such devices is dependant on several factors including the location of the lamp and the ventilation airflow in the room. This study uses a CFD model to evaluate the performance of UVGI ...
