Humidity will damage powders, grains and other dry materials. While moisture-barrier drums preserve the integrity of dry solids, Terra's bulk dry-storage cabinets are added insurance to prevent caking, mold- or microbe-growth, and product deterioration that results from prolonged exposure to ambient air. Outfitted for nitrogen purging, the reinforced 304 stainless steel storage lockers are designed to house fully-loaded bulk drum canisters. 

Storage applications include moisture-sensitive powders used for pharmaceutical manufacturing; agricultural supplies such as grains, soil and fertilizer; bulk solid food ingredients like refined flour and sugar, and toxic/acidic chemicals including Potassium Fluoride, Acrylamide and Sodium Hydroxide.

The cabinet has two full-length steel doors with heavy-duty stainless steel hinges and LiftLatches™ to support their weight and provide a snug, tight seal. Self-closing doors are available, utilizing recessed draw latches; talk to a Terra Product Specialist for more information. Each door has a one-piece, non-outgassing elastomer gasket that keeps nitrogen in, and environmental air out. A digital hygrometer installed in one door is a fast indicator of the relative humidity inside the storage locker. Three-inch-high legs allow access beneath cabinets for cleaning. 

For storage of other bulk items requiring RH control, see Terra's Heavy-Duty Stainless Steel Cabinets available in 36"- and 83"-heights.

Control the amount of nitrogen flowing into the cabinet with Terra's Flowmeter (order separately), easily accessible from an outside panel. Terra's optional RB® (Relief/Bleed) Valve installed at the bottom of the opposing side panel gradually releases gas and air from inside the cabinet as-needed to prevent over-pressurization. This valve can also be connected to an exhaust line for safe venting of airborne particles or fumes. See below for ordering information (must be requested when ordering cabinet; cannot be field-retrofitted).

Nitrogen generator Nitrogen Generators give you a reliable point-of-use supply of up to 99%-pure nitrogen. Eliminate the drawbacks of canisters and 3rd-party suppliers! You control volume, purity and rate; all you need is a clean compressed-air feed. Terra's three sizes of maintenance-free membrane generators meet several capacity requirements are ideal for back-filling or continuous flow into desiccators, glove boxes, vacuum chambers and incubators. 
Drum Pallets
