TDI Ultra Nitro-Flow System for Desiccators

TDI Desiccator Ultra Nitro-Flow System

#1 IN CUSTOMER SATISFACTION FOR 25+ YEARS

TDI Acrylic Desiccator Cabinets provide a clean dry atmosphere to protect moisture sensitive materials/components in storage. To maintain low moisture conditions, a constant dry nitrogen gas supply is required, connected to the nitrogen flowmeter on the desiccator cabinet. The flowmeter regulates the nitrogen gas flow (cu/ft/hr) to the plenum chamber of the desiccator cabinet with the nitrogen gas distributed uniformly through the perforated inside wall of the plenum chamber into each compartment.

All TDI Acrylic Desiccators are constructed with Ultra Nitro-Flow compartment flow-throughs, which achieve a single pressure and atmosphere condition throughout the desiccator. This unique design allows maximum gas flow in both the vertical and horizontal directions and reduces higher moisture humidity conditions between compartments.

This flow design allows for a single automatic bleeder valve per multiple compartment cabinet and eliminates the need for expensive outlet valves for each compartment, required in typical competitor cabinets. The bleeder valve is located in the bottom of the lowest compartment and serves as an efficient outlet drain for the heavier high moisture atmosphere within the cabinet. This design also allows for a single #HM40 Nitro-Save® Humidity Control Monitor sensor system for multiple compartment desiccators.

TDI Desiccators - Ultra Nitro-Flow System

The Ultra-Nitro Flow System offers a highly efficient/economical design to provide rapid recovery to pre-set RH% levels when doors are opened in normal usage functions.

In cases where the Nitro-Save is running when the doors are opened, a positive pressure of Nitrogen flow extends throughout the cabinet plenum wall to all compartments and exits through the open compartment. This precludes any higher humidity room air back fill into the cabinet.

The desiccator cabinet and room atmospheric pressures are similar when the Nitro-Save has achieved pre-set RH% settings and is in the off position. When the doors are opened, air movement between the compartment and the room is slight during the brief timeframe of exposure with minimal RH% level increase in the desiccator.

Cleanrooms generally operate in a 45/55% RH range and this would represent the highest increase condition possible inside an open cabinet compartment.

TDI Nitro Save Humidity Control Monitor for Desiccators

NITRO-SAVE HUMIDITY CONTROL MONITOR
Accurately Controls Pre-Set Relative Humidity (+/- 2% RH)
Reduces Nitrogen Consumption to 90% (20%RH) In Many Applications

TDI's Nitro-Save® Humidity Control Monitor is an economical, reliable sensor instrument that accurately controls pre-set relative humidity (+/-2%RH) in TDI Desiccator Cabinets.
Ultra Nitro-Flow compartment flow-throughs allow for a single Nitro-Save® required for multiple compartment cabinets.

TDI has developed an economic, solid state system that accurately controls humidity and reduces nitrogen consumption. Competitive desiccator brands offer expensive moisture control systems that are dependent on elctro-mechanical switches to control moisture flow. These systems are subject to maintenance with repair/replacement in the long run with compromised reliability. Ironically, most desiccators in service have no RH% moisture control and often consume excess nitrogen to compensate.

The Nitro-Save® Humidity Control Monitor significantly reduces the nitrogen required to maintain pre-set humidity (RH) in desiccators. The Nitro-Save® includes a solenoid control valve and internal sensor system to regulate the nitrogen flow in response to the high humidity set point.
