Hanovia UV system ... compact.

Leading UK-based UV (ultraviolet) systems manufacturing company, Hanovia says that its stand on the benefits of UV in improving the office environment has been vindicated by a recent university study, which showed that UV light kills the germs in office ventilation systems.

“We are very pleased with these findings, as they confirm what we have known for a long time,” comments Hanovia’s managing director Jon McClean. “We have been supplying UV disinfection systems for building services and other indoor air quality applications for many years, with excellent results.”
In the study, researchers from McGill University in Montreal, Canada installed UV systems in the ventilation systems of three modern, sealed office buildings. Following a year of trials, they noticed a significant reduction in work-related illnesses such as headaches and respiratory problems – known collectively as ‘sick building syndrome’ (SBS).
They concluded that UV is an effective way of reducing SBS and should be seriously considered by building operators. The scientists estimate that the initial costs of installing UV would soon be recouped through savings resulting from reduced staff absences.
Following the study, Hanovia says it has received many enquiries about its UV disinfection systems.
One of Hanovia’s installations was with a testing and inspection company based in Surrey, UK. The company’s health and safety manager, on noticing an increased incidence of colds and flu among staff in one section of the building, contacted Hanovia, to install a UV system in the air-handling unit of the building’s air-conditioning system. Since the installation, the number of staff falling ill has fallen by more than 40 per cent.
Compact and easy to install within existing ductwork, Hanovia UV systems are designed for continuous use and can treat air flows of up to two cu m per sec. They expose all air passing through the system to UV at wavelengths that kill all airborne micro-organisms.
“Silent in operation, the systems use no chemicals of any sort and are virtually maintenance-free. The only requirement is that the UV-emitting arc-tube be replaced twice a year. This is a simple operation and can be carried out by general maintenance staff,” he says.
Hanovia specialises in the manufacture of UV equipment for disinfection, deozonation, dechloramination and dechlorination, and for the enhanced removal of total organic carbon (TOC) from ultra pure applications. Other photolysis applications include the removal of N-nitrosodimethy-lamine (NDMA) and methyl tertiary butyl ether (MTBE) from drinking water. Hanovia has installed more than 40,000 systems in more than 100 countries. 
As the only UV system supplier to develop and manufacture UV lamps and monitors, Hanovia says it is generally recognised as the technology leader in this specialised area. Specific lamps are manufactured with enhanced spectral outputs for disinfection, dechloramination, pesticide photolysis and NDMA photolysis.
