Modular Acoustic Enclosures

Isolating large, floor-standing instruments such as full-size scanning electron microscopes can be very challenging. Large enclosures can be difficult to install and move, and large instruments require wide-range accessibility to reach controls and load samples. Herzan’s modular acoustic enclosures can be installed around large instruments, and provide multiple access doors, all while maintaining maximum isolation performance. They can also be customised with a range of vibration isolation and environmental controls.



Our core strategy is to provide carefully articulated vibration, acoustic, and EMI isolation solutions to the global research community. We are committed to delivering exact solutions for customer research needs, improving the overall performance of our environmental isolation systems, and providing the best customer experience possible for all users. In the end, what is important for us is to have the researcher focus on what matters most: their research (and not their isolation solution). We have been privileged to work with some of the most innovative individuals in the scientific research community and are proud to help advance the research performed by our customers.
