Clean Rooms are workplaces where contamination is controlled. The Clean Rooms are said to provide a conducive environment (for research, development and manufacturing of equipment or processes) with a low level of environmental pollutants such as dust, airborne microbes, aerosol particles, and chemical vapors.

In a large, multi-chamber enclosure with a single exit bleed valve, it might take 30 min or more to remove this moisture and recover the relative humidity setpoint. If another door is opened during this time, this recovery time will be extended. In fact, during periods of frequent parts access, the desiccator may never attain the humidity setpoint, and parts could be seriously threatened.

Low-humidity storage of sensitive samples and supplies can now be done in a pass-through chamber. Desiccators in plastic or stainless steel to comply with ISO cleanliness requirements.

Cleanroom Industries can prepare the needed wealth of information specific to designing thru certification of your cleanroom.

Our design team can provide AutoCAD cleanroom design services for most cleanroom projects for architectural, structural, mechanical and electrical disciplines. A thorough inspection of the proposed job site is usually required and includes field measurements, identifying column locations, photographs of the important items and interferences, items to be scheduled for demolition and discussing the total CAD requirements directly with the customer. The number of personnel making the on-site inspections and the number of trips required is determined by the size, duration and phases of the project. Other topics covered by our cleanroom designers include: international design standards, the economics of cleanroom design, high efficiency air filtration, materials used in cleanroom construction, and the provision of clean gases and water.

The design drawings resulting from this process can also be reviewed and sealed by CAT's staff professional cleanroom engineers, registered in the particular state the project is in. The drawings are then ready to be submitted to the local building and code authority for approval and permits. CAT stands ready to make the cleanroom design process a success given any cleanroom requirement.

Our cleanroom design experience is broad based including FDA validatable multi-user/multi-product facilities; medical, pharmacuetical, microbial/cell culture, gene therapy, and health sciences facilities; aseptic filling, medical device, semiconductor, electronic, optics, military/aerospace, and manufacturing cleanrooms.

One of the things to be careful of in respect to cleanroom temperature and humidity control, is specifying them at too low or too tight of a tolerance. That translates again into the cost of construction and the cost of operating your clean room.

If you’re going to build a cleanroom that needs to maintain a specific temperature requirement, but the outside environment around it is at a higher temperature (for example if you’re putting a cleanroom in an open warehouse that has no temperature or humidity control), the cleanroom envelope has to withstand the difference. So you need an R-value in the wall to ensure the heat doesn’t transfer through. You also need a structure that will stop moisture from transferring.
