Change the FFU in the Cleanroom at DTU Nanolab

291 Fan filter Units (FFUs) are about to be changed in the cleanroom over the next half year. The new FFUs are quieter than the existing FFUs and will save 122.000 kWh/year, corresponding to ca. 268.000 kr./year.

Description of the project

The FFU project is a large project that takes place at DTU Nanolab in the cleanroom.

All the FFUs in ceiling of the cleanroom need to be changed in order to maintain and optimize our facility. This is a very long and difficult process that requires time and skills.

We have chosen to begin with one test room, to be able to get an idea of how everything works. The upcoming evaluation will hopefully give an estimation of the rest if the job.


Status on the project

Week 30 - 32
