HIRDLS cleanroom
We were awarded the contract to design and install the mechanical services serving a cleanroom facility at the Department of Atmospheric, Oceanic & Planetary Physics, Oxford University. The cleanroom was designed for the HIRDLS project (The High Resolution Dynamics Limb Sounder). Scientists in the UK and the USA designed a satellite to monitor the global behaviour of our atmosphere in more detail and with greater accuracy than ever before providing the best picture yet of what is happening to the earth's changing climate.

We were responsible for the supply and installation of the complete mechanical services comprising of a fresh air plant, close control air handling system, filtration systems, return air plant and pressure monitoring systems. The two air handling systems were networked via two microprocessor control panels which respond to varying climatic ambient conditions to maintain the temperature and humidity within the facility throughout the year.

These are some images taken inside the cleanroom facility.

The at-rest cleanliness levels inside the main cleanroom housing the large vacuum chamber conform to Class 100 (Fed Std 209E) with a localised Class 10 zone for instrument isolation.
