Storage of Digital Media & Film

XDry and CS Series Desiccant Dry Cabinets have been widely used in many enterprises and public organizations for long term storage of important data and microfilms.

Video Tapes

Proper storage of video tapes of all types protects the tape from organic growth and other damage that adds noise to the images reducing the quality of the recorded material.

CDs & DVDs

Recommended storage of optical disks, both CDs and DVDs, requires specific temperature and humidity within a 2 degree C/5% RH range. High or low temperatures and abnormal humidity can reduce the effective life of these disks risking loss of all the important information archived on the disk.
