  • How to Comply with CDC Guidelines
    1101 W. 13th St, Riviera Beach, Florida Phone: 561.848.1826 https://www.rgf.com/rgf-biocontrols How to comply with CDC Guidelines OVERVIEW Sections of text are extracted directly from the Federal Register Vol. 59, No. 208, 10/28194, to compile this pamphlet. This is not meant to be a substitute for the Guidelines, but a general overview of specific sections relevant to RGF BioControls and its products. Click here for a link: https://www.cdc.gov/mmwr/preview/mmwrhtml/rr5417a1.htm OUR MISSION We believe, once you understand the new CDC guidelines, you’ll understand why our products offer you the best means of compliance. This is based upon a design philosophy that each piece of equipment is designed to satisfy a particular problem and each problem can be satisfied by an individual or combination of products that complement each other. CDC ON NEGATIVE PRESSURE "To control the direction of airflow between the room and adjacent areas, thereby preventing contaminated air from escaping from the room into other areas of the facility. The direction of air flow is controlled by creating a lower (negative) pressure in the area into which the flow of air is desired. For air to flow from one area to another, the air pressure in the two areas must be different. Air will flow from a higher pressure area to a lower pressure area. " HOW RGF BIOCONTROLS CREATES NEGATIVE PRESSURE Our MICROCON ® ExC7 utilizes HEPA filtration and UV light (option) for various room exhaust options. Wall, window or ceiling mounted, they direct air to either outside, back to return air system or corridor.

  • Fast Facts (PDF)
    FAST FACTS According to the National Fire Protection Association, the leading factor contributing to home heating fires (30%) was mainly due to having a dirty chimney (i.e., creosote buildup). Heating equipment (including wood stoves) is the second leading cause of home fires, and third leading cause of home fire deaths. Most fireplace and chimney fires are caused by creosote buildup, and could be prevented. EPA believes there are approximately 13 million fireplaces, 250,000 hydronic heaters, and 8.5 million wood stoves in use nationwide. Five million (57 percent) of the nation’s wood stoves are older, inefficient devices. EPA estimates that if all of the old wood stoves in the United States were replaced with cleaner- burning hearth appliances, an estimated $56-126 billion in health benefits per year would be realized. Smoke from wood-burning stoves and fireplaces contain a mixture of harmful gases and particle matter (PM2.5). Breathing these small particles can cause asthma attacks and severe bronchitis, aggravate heart and lung disease, and may increase the likelihood of respiratory illnesses. Changing out one old dirty, inefficient wood stove is equivalent to the PM2.5 reduction of taking five old diesel trucks off the road. The benefits of replacing old wood stoves and fireplaces: • Saves money, fuel, time, and resources • Up to 50 percent more energy efficient, uses 1/3 less wood • Cuts creosote build-up in chimneys that helps reduce the risk of fire • Reduces PM2.5 indoors and out After start-up, a properly installed, correctly used EPA-certified wood stove should be smoke free.

  • HEPA) Filter - Ultra Low Penetration Air (ULPA) Filter (Also Referred to As Extended Media
    EPA-452/F-03-023 Air Pollution Cocntrol Technology Fact Sheet Name of Technology: Paper/Nonwoven Filter - High Efficiency Particle Air (HEPA) Filter - Ultra Low Penetration Air (ULPA) Filter (also referred to as Extended Media) Type of Technology: Control Device - Capture/Disposal Applicable Pollutants: Submicron Particulate Matter (PM) greater than or equal to 0.3 micrometer (µm) in aerodynamic diameter, and PM greater than or equal to 0.12 µm in aerodynamic diameter that is chemically, biologically, or radioactively toxic; hazardous air pollutants (HAPs) that are in particulate form, such as most metals (mercury is the notable exception, as a significant portion of emissions are in the form of elemental vapor). Achievable Emission Limits/Reductions: HEPA and ULPA filters are classified by their minimum collection efficiency. Many international standards and classes currently exist for high efficiency filters (Osborn, 1989). In general, HEPA and ULPA filters are defined as having the following minimum efficiency rating (Heumann, 1997): HEPA: 99.97% efficiency for the removal of 0.3 µm diameter or larger PM, ULPA: 99.9995% efficiency for the removal of 0.12 µm diameter or larger PM. Some extended media filters are capable of much higher efficiencies. Commercially available filters can control PM with 0.01 µm diameter at efficiencies of 99.99+% and PM with 0.1 µm diameter at efficiencies of 99.9999+% (Gaddish, 1989; Osborn, 1989). Several factors determine HEPA and ULPA filter collection efficiency. These include gas filtration, velocity, particle characteristics, and filter media characteristics. In general, the collection efficiency increases with increasing filtration velocity and particle size.

  • Cabin Air Quality Brief
    Briefing paper Cabin air quality – Risk of communicable diseases transmission The overall risk of contracting a disease from an ill person onboard an airplane is similar to that in other confined areas with high occupant density, such as a bus, a subway, or movie theatre for a similar time of exposure. anywhere where a person is in close contact with others. That said, the risk on airplanes is probably lower than in many confined spaces because modern airplanes have cabin air filtration systems equipped with HEPA filters. HEPA or high efficiency particulate air filters have similar performance to those used to keep the air clean in hospital operating rooms and industrial clean rooms. These filters are very effective at trapping microscopic particles as small as bacteria and viruses. HEPA filters are effective at capturing greater than 99 percent of the airborne microbes in the filtered air. Filtered, recirculated air provides higher cabin humidity levels and lower particulate levels than 100% outside air systems. The cabin air system is designed to operate most efficiently by delivering approximately 50 percent outside air and 50 percent filtered, recirculated air. This normally provides between 15 to 20 cubic feet of total air supply per minute per person in economy class. The total air supply is essentially sterile and particle-free. Cabin air circulation is continuous. Air is always flowing into and out of the cabin. Total airflow to the cabin is supplied at a bulk flow rate equivalent to 20 to 30 air changes per hour. This provides temperature control and minimizes temperature gradients within the cabin.

  • Space Heater Guide
    ENERGY SAVINGTIPS SPACE HEATER GUIDE Heating your home with electric space heaters can easily double or triple your electric bill if you are not careful. Even though they are typically small in size, and often touted as 100% efficient, electric space heaters use a lot of electricity. Most space heaters use on average 1,500 Watts of electricity and cost about 15¢ an hour to operate. While that may not sound like much, it can add up quickly if heaters are left on for several hours a day. Leaving one space heater on for 8 hours a day for a period of one month could easily add an additional $30-$40 to your monthly electric bill. Following are some good tips to help manage your electric bill if you use electric space heaters in your home. Do not heat rooms that are not in use Space heaters should only be used in rooms you are occupying and should never be left unattended. Remembering to turn off heaters when you leave a room can help you save money on your electric bill. Use a thermometer to monitor room temperature Most space heaters do not have individual thermostats or temperature controls, and those that do are often inaccurate or hard to read. Use a separate room thermometer to accurately monitor room temperature and avoid overheating. Your central heating system may be a better choice If you are using multiple space heaters in your home for more than a few hours a day, it may be more efficient to use your central furnace for heating.

  • 3D Printed Aluminum Flat Heat Pipes with Micro Grooves for Efficient Thermal Management of High Power Leds
    www.nature.com/scientificreports OPEN 3D printed aluminum fat heat pipes with micro grooves for efcient thermal management of high power LEDs Chao Chang*, Zhaoyang Han, Xiaoyu He, Zongyu Wang & Yulong Ji* As the electronic technology becomes increasingly integrated and miniaturized, thermal management has become a major challenge for electronic device applications. A heat pipe is a highly efcient two-phase heat transfer device. Due to its simple structure, high thermal conductivity and good temperature uniformity, it has been used in many diferent industrial felds. A novel aluminum fat heat pipe, with micro-grooves, has in the present work been designed and fabricated by using a 3D printing technology. Aluminum powder was used as a raw material, which was selectively melted and solidifed to form the shape of the heat pipe. The sintered aluminum powder increased the roughness of the inner surface of the heat pipe, and the designed micro-grooves further enhanced the capillary forces induced by the wick structure. The wettability, for the working fuid (acetone), was excellent and the capillary forces were sufcient for the working fuid to fow back in the pipe. The efects of working fuid flling ratio, on the heat transfer performance of the heat pipe, was also investigated. It was shown that a flling ratio of 10% gave the best heat transfer performance with the lowest thermal resistance. The 3D-printed fat heat pipe was, therefore, also tested for the thermal management of a LED. The temperature of the LED could be kept within 40 °C and its service life became prolonged. With the rapid development of the microelectronic technology, and the growing need by the information indus- tries, the integration and miniaturization of electronic equipment have become a new development trend 1,2.
