We see a clear upward trend in the number of applications that require a clean environment. Not only in the semiconductor space, but also increasingly in the medical and analytical space.

NTS has a wealth of experience when it comes to cleanliness, from design, through prototype builds, to series production. Across NTS we have clean rooms ranging from grade 5 to 8.
