Leading Dry Room Manufacturers

The control of moisture content in the air requires a room that is sealed to the extent that humidity is eliminated. The answer to how to create these conditions is found in dry rooms that can be easily fabricated and installed in any number of sizes. To guarantee the proper conditions for the room, a dehumidifier unit is used to remove water vapors and create the exacting conditions.

How a Dry Room is Constructed

The most important part of the development of a dry room is the design phase where each aspect of the rooms use is examined. The building of a special environment that is built to resist outside influences has to meet a certain set of standards to qualify as a dry room. Such a room has to be built to meet the requirements of the manufacturing process since the use of these special rooms varies depending on how they are used.

One of the major issues regarding the creation of a unique environment is the number of people who will use the room. Of all the possible factors that can contaminate specially designed rooms, people are the greatest problem since the human body carries many contaminants, viruses, and bacteria. In the design phase of a dry room, engineers develop restrictions for those who will be using the room and their coverings.

The most important determination in dry room design is deciding on the temperature and moisture level requirements. Every dry room is manufactured to meet a specific set of conditions. The type of room used for the production of batteries varies greatly from rooms that are used for producing pharmaceuticals. Each of these situations requires conditions that meet a specific dewpoint and ppmv, parts per million volume.

Each part of a dry room is carefully designed to meet the industrial requirements of the product being produced or tested. The parts of a room designed to meet specific environmental requirements has specially designed wall panels, floors, doors, sensors, and filters that ensure compliance with the needed conditions. In the majority of cases, the room is completely constructed of metal components using high efficiency particulate air (HEPA) filters, which block out 99.9% of contaminants.

Types of Fans and Dehumidifiers for Dry Rooms

Engineered into the design of a dry room is a desiccant or compressor dehumidifier. A compressor dehumidifier cools the air to remove moisture. A desiccant dehumidifier uses a chemical solution to remove moisture from the air. The desiccant chemical dehumidifier adsorbs moisture in the air. The efficiency of a desiccant dehumidifier makes it ideal for use in dry rooms though the compressor version is also used.

The fans of these specially designed rooms are normally of a centrifugal airfoil design and are mounted on vibration isolators to reduce noise and vibrations in the room. The purpose of the fans is to create the air flow to the dehumidifier. Also connected to the system is a condenser that can be air or water cooled with controls to monitor the various factors of a dry room.

The Purpose of Dry Rooms

The creation of special environments has become of increasing importance in the manufacture of specialized products and the production of drugs. Each year, new and more stringent requirements are being legislated regarding production conditions. This has made the development of specialty rooms of critical importance.
