TDI Nitro-Save® Humidity Control Monitor for Desiccators

#HM40 NITRO-SAVE^® HUMIDITY CONTROL MONITOR

Accurately Controls Pre-Set Relative Humidity

Reduces Nitrogen Consumption to 75%+

The primary purpose of desiccators is to establish precise relative humidity levels to protect moisture sensitive materials in a clean environment. Ironically, most desiccators in service have no RH% moisture control and often consume excess nitrogen to compensate.

TDI has developed and economic, solid state system that accurately controls humidity and reduces nitrogen consumption. Competitive desiccator brands offer expensive moisture control systems that are dependent on electro mechanical switches to control moisture flow. These systems are subject to

TDI's Nitro-Save Humidity Control Monitor

maintenance with repair/replacement in the long run with compromised reliability.

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.

The #HM40 Nitro-Save® Humidity Control Monitor accuracy is ± 2۬% RH at 20-80% RH and ± 5% at less than 20% RH. The Nitro-Save® is capable of measuring and displaying humidities in the range: 0-100% RH.

Whenever the humidity rises 2% above the set point the control valve will turn on. Once the humidity decreases 2% below the set point, the control valve will turn off. Each time the control valve turns on, the monitor will begin a 2 hour timer. If at the end of 2 hours the humidity has not reached 2% below the set point, the High Humidity Alarm will sound. Under normal operating conditions the alarm at the end of the 2 hour cycle will indicate a problem such as a lack of nitrogen flowrate or the cabinet door remained open.

The High Humidity Set Point has already been 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.

Nitro-Save® in Acrylic Cabinet Pocket

All TDI Desiccator Cabinets are constructed with our
Ultra Nitro-Flow® compartment flow thrus which achieve a single pressure throughout the cabinet.

This unique system allows for a single #HM40 Nitro-Save® Humidity Control Monitor sensor system for multiple compartment cabinets.

The Nitro-Save® Humidity Control Monitor significantly reduces the nitrogen required to maintain pre-set humidity (RH%) in TDI's Desiccator Cabinets with to 75%+ reduction in nitrogen consumption in most applications.
