CLEAN ROOM TECHNOLOGY
impermeable materials that do not shed particles in normal use, with impermeable joints. Richard Neale of LTC Worldwide* explains: “ The room would normally have an airlock entry, so that it can be operated as a slight positive pressure, thus ensuring that any leakage is from inside to outside. Air entry is via the ceiling using hepa-filters to

Washer vents should be ducted outside the cleanroom with similar protection.
1/10th of a micrometre or 1/10,000th of a mm). Advanced micro-filtration can now take out even finer particles. Cleanrooms are frequently designed to deliver filtered air in laminar flow downwards, to minimise disruption and encourage settlement of the few particles that might still be present, so a large percentage of the ceiling area is occupied by the outlets of multiple fans. This enables a high number of air changes to be achieved, while still maintaining laminar flow. Some
cleanrooms are designed with turbulent flow downwards, where a more uniform reduces the risk of ‘dead spots’ where particles could accumulate unnoticed). The launderer does not need to mirror precisely the cleanroom conditions of every client, but it is important to be able to understand these needs in order to operate a cleanroom which can meet the full range of clients’ requirements.
Barrier washing should be employed, using either washer-extractors or,

process is carried out with the cleanest air possible. Various sizes of HEPA filters are available depending on the requirements of each cleanroom. The drying process is also a very important part in such a site, and it should be emphasized that all our dryers can be configured to avoid cross-contamination with specific components accordingly. According to Danube’s Edouard Colomer: ”There has been an increasing demand on clean room barrier washers and dryers as from our experience, and we are very few manufacturers who can produce these specific models, with the required technology and knowledge. Danube is ahead with cleanroom catalogue thanks to the long experience in laundry equipment production together with the most advanced R+D+I team and thus offering the Danube online connectivity features (IoT) as standard, so clients are able to control the whole
