In industrial production, nitrogen production equipment, as the core device for obtaining high-purity nitrogen gas, is widely used in various fields such as chemical engineering, electronics, food, and medicine. The purity of nitrogen directly affects product quality and production safety, while the moisture content in itaccurateControl ensures the stable operation of the processThe lifeline. As a leading brand in the global humidity detection field, Shaw UK is a global leader in dew point metersxianBrand, itsthe United KingdomSHAWOnline Dew Point MeterSuperdew3by virtue of±3℃Precision and intelligent control capabilities have become the key to monitoring nitrogen purity in nitrogen production equipmentThe 'gold standard'.

Nitrogen moisture content: for nitrogen production processInvisiblekiller”

If trace amounts of moisture in nitrogen are not detected and controlled in a timely manner, it can lead to multiple risks:

1. Equipment corrosionAfter water comes into contact with metal pipelines and valves, it will accelerate oxidation reactions, causing pipeline corrosion, seal damage, and even leading to leakage accidents. For example, a certain steel company did not install a drying device, and the nitrogen generator molecular sieveIt needs to be replaced every 6 months, and after adding a dehumidification process, the service life is extended to more than 3 years.

2. Product deteriorationExcessive nitrogen moisture content in food packaging can accelerate oil oxidation and shorten shelf life; In electronic chip manufacturing, moisture can cause metal migration or dielectric layer short circuits, leading to a cliff like drop in yield. someThe 12 inch wafer fab suffered losses of over 10 million yuan per batch due to uncontrolled nitrogen dew point.

3. process variationMoisture can disrupt the balance of chemical reactions and reduce polymerization efficiency. In the production of polyurethane, excessive moisture can lead to a wider molecular weight distribution of the product and a decrease in mechanical strength.

the United KingdomSHAW Online Dew 3 is designed specifically for nitrogen production equipment, and its core technology directly addresses the pain points of moisture control:

1. High accuracydetectionUsing alumina capacitive sensors with range coverage-Measurement accuracy within the critical range of -60 ℃ to -40 ℃ from 100 ℃ to+20 ℃±3℃, can be stably identified0.1ppm level water vapor variation, far exceeding industry standards.

2. Fast response and stabilityResponse time for wet to dry conversion<120 seconds, dry to wet conversion<20 seconds, ensuring real-time data even in the face of fluctuations in raw gas flow rate.

3. Intelligent closed-loop control: Through4-20mA standard output, can be linked with the drying device to automatically adjust parameters. For example, when the dew point approaches the threshold of -40 ℃, the system automatically starts the molecular sieve adsorption tower regeneration program to stabilize the humidity within the process requirements.

4. Full process monitoring and traceabilityBuilt in data recording function can trace historical humidity curves, combined with process parameter analysis, predict potential problems in advance, optimize desiccant replacement cycles and equipment maintenance plans.
