The biorepository of one of the largest research hospitals in the country has standardized their bulk liquid nitrogen vapor storage to the Cryosafe CRYOGUARD CGSP-4.

This system provides more storage than all other systems in it’s class as well as some other powerful features.

This system provides redundant protection for the level of the liquid nitrogen through 8 indipendant sensors instead of a single level sensor, providing safety against both overfill and overflow.

The controller provides the option for sequential fill when multiple controllers are networked together withing the workspace.  This saves money by utilizing the line to make sure all tanks are “topped off” while the line is cold and eliminating excessive liquid N2 use to cool the lines to fill at different times.

It also provides one of the lowest rates of liquid nitrogen use in the industry coupled with ease of use and intuitive controls.

If searching for a bulk vapor system this system is likely the best choice for your space.
