How S-1500 Nitrogen Storage Cabinets work:

Nitrogen “N2” is served as an inert gas replacement for air where oxidation is undesirable. Nitrogen is the standard means for contamination-free storage chambers. N2 does not react with stored materials and it can be isolated and purified relatively economically.

Cleatech S-1500 Nitrogen purge cabinets use a removable plenum chamber designed to provide a continuous laminar flow of nitrogen over the moisture sensitive devices (MSD) maintained within the dry storage desiccator cabinet. (see the nitrogen flow diagram in the left). The volume of nitrogen purged depends on the volume of the storage cabinet, the moisture contained within the contents of the cabinet, the Related Humidity of the external environment and how often the desiccator cabinet is opened.

Also using Cleatech’s “Automatic Nitrogen Purge System” would reduce Nitrogen Consumption to 75% in desiccators (dry boxes).

Acrylic or ESD safe PVC material on S-1500 nitrogen dry storage cabinets and desiccators perform well and of course provide a visual advantage over a stainless steel cabinet.

• 1/4″ thickness Clear/Amber Acrylic, Static-Dissipative PVC or Non-Dissipative PVC
• Stainless Steel door hinge for maximum door support
• Metal Lift-and-turn Compression Latch (Lockable latch is also available)
• Non-Adhesive one-piece door sealing

• Plenum chamber uniforms gas distribution in multi-chamber cabinets
• 304 stainless steel door frame extend service life and improve sealing performance
• Stainless steel racks allow shelf placement at one-inch increments
• Grounded rack, hinges and door latch provide additional ESD safety

• An Automatic nitrogen purge control unit provides automatic low-humidity control capable of measuring and displaying humidity inside the Desiccator cabinet in the range: 5-100%RH, Accurately Controls Pre-Set Relative Humidity (+/- 2% RH). While inside humidity level is below-set point the system provides low purge (2-20 Cubic feet per hour). Maintain positive pressure inside the desiccator chambers to have free contaminants and moisture environment. When the moisture climbs above an adjustable set point the system automatically activates high-flow purge (0.5 – 15 PSI).
  • In One-channel purge control unit, there is only one humidity sensor which is installed in the lower chamber of multi-chamber desiccators. There are some perforated holes between chambers which connect the chambers together.
  • For more critical requirements, select the Multi-Channel nitrogen purge control unit. For each chamber, there is a separate sensor and controller. When any door opens the system responses much faster to the sudden RH% increase.

• External Mount flowmeter with an adjustable valve for manual control of gas flow
• Pressure relief valve relieves excess nitrogen (N2)
• Heavy duty acrylic shelves with 25 lbs. Weight capacity
• Heavy duty 304 Stainless steel shelves for up to 35 lbs. weight
• Heavy-duty Powder coated steel stand for lifetime durability
• An option of Lockable casters for enhanced mobility or Leveling mount
• Door Cam-lock or Locking brackets for securing the desiccator cabinets
