High Access Acoustic Enclosure

Complex instruments and experimental setups using multiple parts can often require lots of space to operate, and require accessibility to many areas. To maintain ease of access, while still maximising isolation and ensure performance, Herzan have developed The Crypt. Featuring wide opening doors with 180° access, The Crypt can protect even the most demanding equipment. A range of customization options are available, including EMI shielding, temperature control, and custom sizes.



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.

CN Tech are the exclusive Herzan distributor for:

United Kingdom, Republic of Ireland and Europe.
