Clean Room Temperature And Humidity Range

Looking at cleanroom temperature.

Clean room temperature and humidity range.

Clean rooms need a lot of air and usually at a controlled temperature and humidity. Relative humidity is one of the environmental conditions usually specified for cleanroom operations. Variation in humidity means difficult adjustments in bed temperature. In general the temperature of a cleanroom should be 21 degrees celsius or 69 8 degrees fahrenheit.

This means that in most facilities the cleanrooms air handling units ahu consume over 60 of all the site power. Humidity control is also impor tant at liquid crystal display plants and paint plants. Relative humidity in a semiconductor cleanroom is typically controlled to a target value somewhere within the 30 to 50 percent range and with tolerances as narrow as 1 percent for some areas such as photolithography or even less for deep ultraviolet processing duv and relaxing to. That translates again into the cost of construction and the cost of operating your clean room.

In this case the durability and accuracy of the humidity sensor is very important. Usually a fluctuation of 2 degrees celsius is permissible. If you were to set your temperature at 70 degrees and 50 relative humidity at 68 degrees that would be 55 relative humidity. The clean room applications range from the fabrication of microscopically small sub assemblies electronic devices and instruments to the increasing demand for more sterility and purity in drugs foods and a germ free atmosphere for medical and biological applications.
