IsoDry desiccator cabinets are the latest, patent-pending innovation in desiccators from Terra Universal. Desiccators are containers designed to reduce relative humidity (RH) for moisture-sensitive stored items, either by purging the container consistently with nitrogen, using silica gel desiccants or pulling vacuum. The IsoDry desiccators use nitrogen to accomplish this task, both in achieving and maintaining a humidity “set-point.”
How do IsoDry Desiccators Work?
Terra’s desiccator cabinets rely on a basic tenet of natural physics: buoyancy. Buoyancy is a function of density and mass between at least one fluid and another material. In our applications, it relies specifically on the fact that purified nitrogen is less dense than atmospheric air. Pumping nitrogen into an enclosed environment pressurizes both the air and the nitrogen, and the difference in densities causes the nitrogen t
