ETS-Lindgren's Single Sliding Door (SSD) answers the growing need for bi-parting special access door requirements in medical applications. It incorporates proven RF sealing technology with an internal pneumatic actuator to drive the guided mechanism plates and expansion strip outward, making for a perfect alignment. The pneumatically sealed door system represents a breakthrough in shielding, with a flat threshold for smooth patient transport. Shielding includes RF protection for MRI, and can be supplemented with acoustic enhancements, lead or passive shielding requirements.
