By controlling relative humidity (RH) at the Troy (CL) UK site in St Helens – which produces contact lenses – environmental control specialist Munters have been able to maintain consistent conditions for optimum production.
As pharmaceutical products are more 'moisture-sensitive' than most it is imperative that the relative humidity (RH) and temperature in the production area remain constant. Back in 1984 a Munters desiccant dehumidifier was installed to do just this. This system has worked exceptionally well and in 2005 they finally decided it was time for a replacement. A new system was installed last year which should give another 23 years reliable service.
Ken Smith from Troy (CL) UK says " The old system provided us with a long and faithful service and was finally replace by a new one. This is quieter and runs for less time, resulting in an energy saving as well".
