For 90 years Hanovia, tucked away in the Berkshire town of Slough in the UK, has been quietly innovating. From its early days making UV lamps for treating skin conditions to today’s high-tech UV water treatment systems, the company has always been at the forefront of UV science and, at 90, age is no barrier to innovation!

Hanovia is now a world leader in UV disinfection for applications as diverse as food and beverage processing, pharmaceutical manufacturing, brewing, electronics, swimming pools, buildings, ballast water and fish farms.

To celebrate its 90th anniversary the company hosted a celebration at its HQ on 3 November which was attended by the Mayor of Slough, Shafiq Chaudhry, Rob Anderson, the Leader of Slough Borough Council, representatives from SEGRO (which runs Slough Trading Estate), journalists and ex-Hanovia employees.

After a brief talk by John Ryan, Hanovia’s Managing Director, about Hanovia’s long history – and looking ahead to the next 10 years – visitors had a short factor tour which was followed by a cake-cutting ceremony and lunch.

“It was fantastic to see so many ex-employees on the day – and we were honoured that the Mayor was able to attend.” Everyone found John’s talk interesting and the factory tour was the first time some of the visitors had even see a UV system, so there were plenty of interesting questions.
