Covid-19 has focused awareness on the importance of indoor air quality. Italy was hit particularly hard by the virus. The FCZ H oers a solution that provides comfort whilst the sanitising action of the photocatalytic system helps to limit the spread of infections. Based on Aermec’s flagship FCZ range of fan coils, the FCZ H cooling capacities range from 0.8kW - 8.6kW and heating capacities from 2kW – 17.1kW. It combines quiet operation, low electricity consumption and reliability with the sanitising benefits of an integrated photocatalytic system. Numerous studies confirm the eectiveness of photocatalytic devices can make legionella, fungi, mould and other virus bacteria such as flu’ and SARS inactive. The unit incorporates an Ultra Violet C (UVC) germicidal lamp with a Titanium Dioxide (TiO2) surface. When radiated by the lamp, any pollutants in the air flow are broken down into harmless substances by the free radicals created by the UVC and the TiO2 surface. The UVC lamp is shielded, so the device is harmless and has no eect on people in the room. Titanium Dioxide (TiO2) possesses a high degree of thermal and chemical stability. It is not toxic for humans and is widely available, bio-compatible and highly sensitive to UV light. The catalyst which resembles a honeycomb, increases the photocatalysis reaction surface, which maximises and guarantees system e—ciency. The interaction of the catalyst with the UV light (photocatalysis) creates an eect that attacks, breaks down and eliminates the polluting agents. Maximising efficiency Over 90 FCZ H units have already been sold for a major o—ce development in London, and the units are also being used in a number of hospital projects. The sanitising benefits make it an ideal solution for any indoor places including nursing homes, laboratories, pharmaceutical companies, hotels, schools, beauty salons, o—ce buildings and any other building requiring guaranteed hygienic air flows. The FCZ H fan coil unit oers maximum comfort and safety, with minimum operating noise – it is the quietest Eurovent certified fan coil on the market with noise levels down to 23dB(A). Environmental issues have been addressed by reducing the power consumption down to four watts and avoiding the use of refrigerants in indoor ambients. Installation and maintenance activities have also been simplified to reduce operating costs and maximise e—ciency. The air filter is easily removeable for cleaning. Options include: • Three speed AC motor or infinitely variable EC motor for optimal sound and energy performances • Two or four-pipe systems • Fixed and adjustable grilles with CFD optimised air flows • Pressure independent valves ensures constant water flow in all conditions • Easily removable G2 air filter • Wall mounted or wireless remote controls Manufactured using a polyester powder- coated galvanised steel housing, the absence of unpainted surfaces on the FCZ H reduces corrosion risks. The fan coils can be floor or wall mounted units as well as ducted or recessed depending on requirements, addressing a variety of installation requirements. As with Aermec’s other fan coil units, depending on spatial limitations the FCZ H can also be used for retrofits. When it comes to Covid-19 there are many questions unanswered, how the virus spreads and the role that HVAC systems can play. There have been numerous papers published since the outbreak but no reports of transmission through HVAC systems. Building owners can help minimise the spread through the cleaning of air by using a UVC light and photocatalytic oxidation equipment which can inactivate and reduce the amount of microbiological contaminants. Aermec is planning to roll out UV lamps across its heat recovery ranges. This is a key priority for the company in a bid to help customers improve the quality of their indoor air and minimise the risks of infection.
