Nitro-Save® Operating Instructions

RetroFit Installation Instructions for Existing Desiccators

 


The primary purpose of desiccators is to establish precise relative humidity levels to protect moisture sensitive materials in a clean environment. TDI has developed an economic, solid state system that accurately controls humidity and significantly reduces nitrogen consumption.

 

The Nitro-Save® Humidity Control Monitor significantly reduces the nitrogen required to maintain pre-set humidity (RH%) in TDI’s Desiccator Cabinets up to 90%+ reduction in nitrogen consumption in many applications. (See Graph)

TDI Independent Test Results- Conditions May Vary by Application

 


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. Whenever the humidity rises 1% above the set point the control valve will turn on. Once the humidity decreases 1% below the set point, the control valve will turn off. Each time the control valve turns on, the monitor will begin a 1 hour timer. If at the end of 1 hour the humidity has not reached 1% below the set point, the High Humidity Alarm will sound. Under normal operating conditions the alarm at the end of the 1 hour cycle will indicate a problem such as a lack of nitrogen flow rate or the cabinet door remained open.

The High Humidity Set Point has been pre-programmed to 20% RH, which represents general electronics requirements. The RH % settings can be increased for less critical humidity control or decreased for more critical humidity control.

To maintain low moisture conditions in TDI Desiccator Cabinets, 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 with the nitrogen gas distributed uniformly through the perforated inside wall of the plenum chamber into each compartment.


TDI Desiccator Ultra Nitro-Flow System

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 #NS16 Nitro-Save® Humidity Control Monitor sensor system for multiple compartment desiccators.
