Terra Universal's SmartDesiccator is an easy access, low-humidity storage system that allows the user to program a low percent relative humidity set point in seconds. Using a quick-response feedback system to activate a dry nitrogen purge, the system continuously monitors and maintains the humidity level to prevent moisture damage. The smart controller reduces nitrogen expenses by purging only when necessary, and minimizes overpressures that stress cabinet seals. A one-piece, non-outgassing gasket and automatic bleed valve maintain a safe cabinet pressure. The SmartDesiccator is available with one or two chambers in stainless steel, acrylic, or static-dissipative PVC.
