About us
Designing and Building Tomorrow's Facilities Today.
What we do
CleanSpace designs, manufactures, and installs the world’s most advanced controlled spaces (clean spaces) using its design-to-deliver approach, CleanFit. This approach brings complex projects online months faster and with guaranteed costs, providing certainty and expertise that is vital for small- to mid-sized companies in rapid growth mode.
How we do it
Everything starts with our promise.
On commissioning day, there can be no compromises with a new dry, cold or clean space - surprises are costly. With our process architecture methodology, assumptions are tested and refined very early in design. "No compromises" is also a promise that governs every CleanSpace employee and every client interaction.
Smart design accelerates manufacturing
Like the cleanspaces we install and commission, our design process is modular. We save days, weeks, or even months by manufacturing in logical phases - we don't wait for final design sign off.
Open, often communications build confidence
One integrated team oversees a client's design to installation timeline, and they report on milestones weekly. There are no surprises, no compromises.
In an industry where overruns routinely exceed 30%, CleanSpace is an outlier. When we commit to a budget and timeline, we commit. This is our promise, and living it is central to how we train and compensate our people.
