UVent ‘In-duct’ units provide the most powerful and e cient air sterilisation unit of its type available on the market. These fully scalable duct-mounted units can deal with any airflow duty and can easily be retro-fitted into existing ductwork installations. Single or double rack high e ciency UV tubes and the ability to stack multiple units create the most comprehensive microbiological destruction zone and formidable single pass performance. Airflows up to 12.6m3/s can easily be accommodated without any compromise in sterilisation e ciency and for duties above this, twin banks can be used in a bifurcated format. Independently tested with guaranteed results Mansfield Pollard has always recognised the importance of independent testing and continue to use trusted third-party partners in order to refine and develop all product lines. All UVent products have been subjected to rigorous independent testing and scientific scrutiny under laboratory conditions to reflect actual live HVAC conditions. Leeds University Pathogen Control Engineering Institute (PaCE) undertakes research in all aspects of the built environment in which the presence of pathogens influences design. Steady state room tests were conducted which consisted of a specially constructed aero-biology test chamber to simulate a room inhabited by an infectious individual who is constantly emitting harmful organisms. The ceiling jet and mobile unit were tested individually by placing them into the sealed ventilated chamber with a constant supply of airborne bacteria introduced. Tests were carried out in the chamber to determine the e ciency of the device in terms of its ability to inactivate a range of airborne micro-organisms. Testing of the duct mounted units necessitated the construction of a single pass test rig consisting of 10m ductwork with capacity to introduce aerosolised cultures of micro-organisms introduced from a 6-jet collision nebuliser at one end. Various air flow rates and pressures were tested across the UV sterilisation unit with a 6-stage sampler downstream to capture the results for analysis. Other recognised specialists in pathogen control were engaged to further test and verify the results prior to publication, including Professor Clive Beggs of Bradford University (a pioneer in the control of infection in hospitals) and scientists at the world-famous Porton Down Research facility in Wiltshire. Comprehensive results for various air volumes for over 30 dierent pathogens (Including coronavirus SARS and Influenza) are freely available, highlighting kill percentages in excess of 99.9%. Simple, efficient and safe UVent’s unique design with both the reaction chamber and high intensity UV-C lamps running parallel to the airflow rather than perpendicular, has led to incredible gains in energy e ciency. This is particularly relevant to the duct-mounted UVent product where the same irradiation value can be achieved with a 65% reduction in power usage when compared to vertical tubed units. In addition, there is a large reduction in the amount of radiated heat produced (in excess of 70%) which significantly lessens the cooling load on the central air handling unit. With 80% less UV-C lamps needed to create the same UV-C output there is less resistance to airflow leading to increased fan e ciency and also less requirement for any critical maintenance (tube replacement). Safety of UVent products are of critical importance, with exposure to UV-C being particularly harmful. All models have automatic fault monitoring systems to maintain optimum working e ciencies. Clearly visible LED indicators are positioned on the face of units to highlight individual lamp status and general faults and a digital ‘hours run’ recorder guarantees lamp replacements are undertaken at the appropriate time. Integral safety lamp shutdown features are built in as standard to prevent any exposure when accessing the units. This permits straightforward preventative maintenance with simple service packs available directly from UVent containing all components necessary for a full-service including replacement lamps and reflectors, filter pads, gloves, cleaning cloth and fluid. Supporting the economic recovery All UVent products have been proven to destroy viruses and bacteria. including coronavirus, and this has brought huge benefits to the healthcare market. However, UVent is seeing more and more market sectors adopting / introducing this technology, including schools and colleges, hotels, factories, retail premises and commercial o ces. “As a 154-year-old business, we have an enviable record of reacting positively to changing market forces through product innovation, flexibility and business agility. Allied with our inherent core values of collaboration and continuous development, the Mansfield Pollard brand remains a symbol of British manufacturing excellence. We are proud to be at the forefront of the fight to arrest the spread of the virus and proud to be able to contribute to the UK’s societal bounce-back, allowing more people to get on with their normal lives and get our economy working again.’’ Lou Frankland, Managing Director Mansfield Pollard co-owners Lou Frankland and Bryan Bentley Compact units are sized to replace a standard ceiling tile The portable version is currently proving popular
