Decontam has been operating for over 35 years and specialises in cleanroom textile services. Decontam once again chose to rely on Viessmann's many years of experience for its site in Beelitz, Brandenburg, to design laundry facilities that are very specifically tailored to the requirements of cleanroom applications.

FFUs make ISO 5 cleanroom class possible with low-turbulence flows

As part of the project, a new cleanroom laundry with cleanroom class ISO 5 was to be built in 2016. The requirements for a class ISO 5 cleanroom are very high: a very low-turbulence flow was achieved by equipping the entire cleanroom ceiling with FFUs (Filter Fan Units). A plenum was also built above the cleanroom ceiling, in which fans and filters were installed to ensure the purity of the air flows.

Viessmann Technologies supplied 120 m² of cleanroom flooring and ceilings for the new cleanroom. The package also included the cleanroom walls and ventilation technology.

Material and personnel airlocks prevent particle inflow into the cleanroom

The cleanroom at Decontam is where the cleaned and dried laundry, which was previously loaded from the back outside the cleanroom, is folded and packed in films under cleanroom conditions. The laundry pieces are then transported to the picking area through a ventilated material lock and returned to the customer.

Two personnel airlocks allow cleanroom-compliant access.

A connecting service office has a clear view into the cleanroom through glass return air ducts.
