This project adds a 2,500 SF cleanroom to the existing facility in Minnesota. The project adds AHU for conditioning the space with a make-up Air unit providing fresh air and a separate AHU for the gowning space. Our design added two air-cooled chillers and boilers to support the addition and included piping to deliver the Vacuum, N2, helium, and CDA. Dunham provided mechanical and electrical engineering services for this project.
