Meridian, Idaho, April 2007 - A new "DynaVac" system from REYCO Systems® provides dual functions of liquid removal and surface decontamination using high output ultraviolet-C ("UVC") energy. The DynaVac system may be used to remove water, syrups and other liquids while simultaneously decontaminating food product and conveyor surfaces of mold, bacterial and viral contaminants using "UVC Emitters®" from Steril-Aire, Inc. (Burbank, Calif.). The unit is designed primarily for use with fresh-cut foods and may also be used to dewater and decontaminate processed foods such as diced potatoes immediately prior to freezing or cooling.

Dual-suction plenums below a precision-driven stainless steel belt are used to remove fluids. In addition, two decontamination hoods equipped with UVC lights effectively kill or inactivate viruses, bacteria, mold and yeast. The DynaVac unit also incorporates a product turnover section between the two decontamination hoods: Agitation shafts gently distribute and turn the products across the belt, allowing optimal liquid removal and maximum surface exposure to the UVC germicidal energy.

The UVC Emitters are housed in watertight hubs and sheathed with a proprietary material to provide a food-grade, shatter-resistant design. The decontamination hoods are hinged for easy cleaning with high-pressure water or chemical foam. Each hood is provided with its own safety switch to shut down the UVC lights when lifted. Units may be customized with different hood and turnover configurations depending on the application.

Steril-Aire's multi-patented UVC technology destroys Coliform, Salmonella, E. coli, Staphylococcus, Listeria, and other bacteria through disruption of the DNA or RNA structure at the cellular level. UVC treatment is approved by the USDA and FDA for surface decontamination, does not require irradiation labeling, and will not alter the look or taste of most food products. The Steril-Aire lights produce no ozone and generate very little heat, utilizing minimal energy and maintaining effective output at temperatures near freezing.

In addition to the DynaVac system, REYCO offers a range of other equipment utilizing Steril-Aire UVC Emitter™ technology for various applications in food plants. Offerings include patented UVC tumbling drums and standard and custom-designed UVC conveyor hoods.

New Orleans, May 2006 - A research study conducted by the U.S. Department of Agriculture's Agricultural Research Service has found that high-output ultraviolet-C (UVC) lights are effective in improving the quality and shelf life of fresh-cut cantaloupe melon. The findings of the study, which used high-output UVC lights manufactured by Steril-Aire, Inc., have far-reaching implications because the $15 billion fresh-cut produce industry is one of the fastest growing categories in the U.S. food market today.

Olusola Lamikanra, a chemist with ARS's Food Processing and Sensory Quality Research Unit and leader of the study, says: "What is holding fresh-cut fruits back are the physiological and biochemical changes that occur when they are processed and stored. Compared to vegetables, fruits commonly used for the fresh-cut market generally have a higher pH and water content, making them more vulnerable to microorganisms and enzymatic changes." When fruit is sliced, he noted, sensory qualities such as taste and texture will be altered, nutrients lost, and bacteria and molds introduced.

In the study, researchers investigated the potential for high-output UVC light to diminish these vulnerabilities. They compared three groups of cut cantaloupe: (1) melon exposed to UVC light after processing - the most common method of UVC application; (2) melon exposed to UVC during the cutting process; and (3) a control group of non-UVC-treated cut fruit.

The UVC light source was a 24"-long, food-grade Steril-Aire "UVC Emitter™". The research team cut the melons uniformly and exposed them to UVC irradiation for approximately four minutes. The cut fruit from all three test groups then underwent a series of tests to measure enzymatic activity, respiration rate, texture and microbiological activity. In addition, nine experienced panelists performed a descriptive sensory analysis of cut melon samples.

According to the study, "Results indicate that while post-cut application of UV improved shelf life of cut cantaloupe melon, cutting fruit under UVC radiation further improves product quality."
More specifically, the study found that UVC radiation during processing reduced rancidity and improved firmness retention in the stored fruit. It also reduced spoilage microorganisms such as mesophilic and lactic acid bacteria.

UVC energy is best known in the food industry for its ability to kill or inactivate mold and bacteria that may contaminate food products. The cantaloupe study supports this premise - yet it provides important new evidence that UVC also produces favorable enzymatic changes during processing. "Cutting a cantaloupe under UVC light causes a hypersensitive defense response to take place within its tissues," states Lamikanra. He says the reaction can be compared to the way we create antibodies when confronted with environmental stresses. This UVC-induced stress response helps explain how the fruit stayed fresher for several days longer.

Lamikanra plans to conduct a second phase of the study to investigate how one or more exposures to UVC light may be combined with other technologies to further enhance produce shelf life and quality. By extending the shelf life of high-value perishable food items, food processors can achieve greater profitability and operational efficiencies.

Burbank, Calif., February 2006 - A new mobile decontamination unit equipped with multi-patented, high output UVC technology is now available from Steril-Aire. Called the "Remedial In-Room Decontamination System (RIDS)", it provides a safe and effective way to decontaminate surfaces infested with mold (such as Stachybotrys and Aspergillus), viruses (e.g., colds, flu, SARS and measles); and bacteria (including TB, Legionella, E. coli, Listeria, Salmonella and whooping cough).
.
The user wheels the RIDS unit into the infested area, leaves the room and turns on the unit remotely, allowing the energy from the high output UVC Emitters™ to decontaminate walls, tabletops and other surfaces. A 12' x 12' area can typically be decontaminated in approximately 24 hours. Multiple RIDS units may be used to treat larger areas.

Steril-Aire UVC technology uses no chemicals, produces no ozone or other toxic contaminants, and minimizes worker exposure during the decontamination process. The high output UVC energy quickly kills or inactivates microorganisms that contribute to poor IAQ and/or the spread of infectious disease.

The portable RIDS unit is suitable for any type of residential, commercial, industrial or institutional building. Applications include residential and commercial surface mold remediation; food preparation and processing areas; surface decontamination in hospitals and health care facilities; and surface treatment in DNA laboratories to prevent cross-contamination.

The company's latest patent covers the application of UVC light to break down airborne volatile organic compounds (VOCs) and common organic odors. Using the patented methodology, Steril-Aire's germicidal UVC devices can reduce VOC and odor concentrations. As a result, the air in a mechanically ventilated space can smell cleaner because it is cleaner.

"Steril-Aire already has a formidable portfolio of patents covering the irradiation of cooling coils, NEMA 4x enclosures, and many other aspects of the design and application of UVC light. However, this marks the first time UVC will be patented for its ability to reduce contamination from VOCs and odors," states Robert Scheir, Ph.D., president of Steril-Aire, Inc. "This added dimension of performance applies not only to new devices manufactured by our company, but also to thousands of our existing UVC installations."

As another part of its ongoing technological improvement program, the company has also begun receiving its new listings under UL 1995. The first listing applies to "X-Mount" (Model SE) and "X-Mount Plus" (Model SEN) UVC Emitters™, which are externally mounted, single-end-tube style commercial UVC devices.

Steril-Aire has become a leader in UVC technology because its multi-patented devices offer greatly increased output in cold and/or moving air environments, providing superior germicidal performance and longer life in HVAC and food processing applications.

RESEARCH STUDY FINDS HVAC-STYLE "UVC" LIGHTS REDUCE FUNGAL CONTAMINATION IN BUILDING AIR-HANDLING UNITS


Tulsa, Oklahoma, January 2002 - A research study, conducted in a 286,000 sq. ft. office building here, has found that Steril-Aire "UVC" light fixtures are effective in reducing fungal contamination within air-handling units (AHUs). The findings are significant because fungal contamination is recognized as a continually present and widespread phenomenon in building HVAC systems, and a major contributor to building-related illnesses, including both infectious and hypersensitivity diseases.

The study, led by Dr. Estelle Levetin, one of the nation's top mycologists (University of Tulsa Faculty of Biological Science), involved a total of eight air handlers: four test units treated with UVC lights manufactured by Steril-Aire, Inc. (Cerritos, Calif.), and four control units with no UVC. The research team took air and surface samples from all of the air handlers in the spring (before cooling season) and fall (after cooling season) of the same year. The objective was to prove that fungal contamination of HVAC systems is a year-around condition that can be effectively reduced through proper application of UVC.

The surface samples, taken from the air handlers' insulation prior to cooling season and before the UVC lights were turned on, contained nearly identical mean concentrations of fungi - approximately 212-213 x 103 colony-forming units (CFU)/cm2. After cooling season, in the untreated (control) air handlers, fungal concentrations increased more than tenfold to 2,240 x 103 CFU/cm2; while in the UVC-treated air handlers, concentrations decreased to 30.5 x 103 CFU/cm2. This is nearly a 99 percent reduction in the contamination of the insulation surfaces.

Similar results occurred with the air samples. Sampling in the spring showed mean concentrations of fungi to be similar in the control and test units - about 21-22 x 102 CFU/cm3. After cooling season, the control units with no UVC experienced a tenfold increase in fungal concentrations (to 239.52 x 102 CFU/cm3), while the UVC-treated air handlers experienced nearly a tenfold reduction in fungi ((to 2.98 x 102 CFU/cm3). Again, this amounted to a 99 percent reduction in the number of microorganisms circulating through the air handling units from and to the occupied space.

Dr. Levetin concluded that this "germicidal UVC irradiation may be an effective approach for reducing fungal contamination within AHUs."

Steril-Aire, manufacturer of the devices used in the study, holds multiple patents for the development and application of UVC lights that provide optimum performance in HVAC systems and other cold and moving air environments such as food processing plants.

Forrest Fencl, company president and CEO, states: "This scientifically acquired data provides further evidence of the beneficial effects of the Steril-Aire product and approach. Statements from the operators of the facility used in the study and hundreds of others support these findings. Building operators consistently report that the use of UVC yields a noticeable difference in air quality, while enabling them to reduce or eliminate costly cleaning of coils, drain pans and plenums. Also, because there is no mold or organic buildup to compromise performance, air handling equipment runs more efficiently and energy costs are reduced."
