The W-XL is a complete solution, which covers the entire process consisting of compressed air generation, compressed air
purification, nitrogen generation, nitrogen purity monitoring, nitrogen supply control and even nitrogen distribution.
> The application of PSA technology enables nitrogen purity to reach up to 99.9995%, while maintaining the flow rate and pressure
> Nitrogen purity range: from 95% to 99.9995% (depending on flow rate and pressure)
> Nitrogen flow range: from 100 to 40000NL/min
> Maximum nitrogen output pressure: 7.5 bar (direct output) or 20 bar(supercharged output)
> 10-inch color touch screen
> The gas purity can be monitored and displayed in percentage or PPM in real time
> The curve of nitrogen purity can be monitored and recorded in real time
> The multi-stage air purification system of the front part of the molecular sieve ensures the purity of the outgassing and the lifetime of  the molecular sieve
> Language: English and Chinese
> Data communication interface: RS232, analog input and output, alarm signal output
> Noise：73±dB
> IP Protection of air compressor: IP54, low air pressure alarm
> The whole system includes air compressor, compressed air tanks, refrigeration dryers, purified compressed air tanks, PSA nitrogen  generator mainframe, nitrogen tanks,nitrogen transmission, nitrogen augmentation, nitrogen main line, nitrogen distribution

Application:
> Central laboratories, analysis and testing centers, liquid quality analysis platforms, experimental teaching platforms and other lab customers
> Food packaging production lines, semiconductor production lines, pharmaceutical workshops, high-precision metal processing lines and other industrial customers

Leading and Pure
> With the triplex filter, the output gas particle diameter is less than 0.01μm.
> With the refrigeration dryer and the absorption tower, low water content can be achieved.
> No use of plasticizer and phthalate to ensure health during its usage.
> Continuous nitrogen purity monitoring to ensure the quality of gas.

Safe and Reliable
> Industrial grade PLC control, stable and reliable
> No risk of high temperature, low temperature or high pressure
> Safety alarm and alarm signal output
> Overtemperature protection of the air compressor
> Automatic pressure relief to ensure the compressor to start under normal pressure, and to extend the life of the compressor

Economic and Convenient
> Avoiding rent, deposit, transportation cost and safety management cost, and its long-term operation cost is lower than cylinder  nitrogen and liquid nitrogen containers
> Good quality control, of compressed air long service life of nitrogen generator
> Less maintenance parts, controllable operation and maintenance cost
> Gas production by electrification, fast and convenient

Other Optional function：
Monitoring
> Gas purity monitoring
> Outlet pressure monitoring
> Nitrogen moisture content monitoring
> Nitrogen flow rate monitoring

Management and data recording
> Laboratory access management and two-level password management. Administrators and operators have different access rights respectively.
> Purity&time and pressure&time curve display.
> Purity and pressure data can be stored in real time, accessed and viewed at any time, and can be traced effectively. The upper storage limit is 10000 pieces of data.

Alarm function
> Purity monitoring and lower limit alarm function
> Pressure monitoring and upper & lower limit alarm function
> Nitrogen moisture content monitoring and upper limit alarm function
> Nitrogen flow rate monitoring and upper & lower limit alarm function

Fast calibration
> The operator can calibrate sensors onsite (additional preparation is required for standard conditions).
> The calibration data are stored in the data center.

Condensate drainage management
> A unified drainage management for the air compressor,the storage tank and the filter
> The storage tank is automatically drained (drainage cycle can be set)
> All drainage is collected to one pipeline for final treatment

Maintenance management
> All parts to be maintained are displayed on the touch screen PID chart, which is specially displayed two months before the maintenance time to remind the customer
> Maintenance help function: the replacement process, method and diagram for each consumable will be directly displayed on the screen to help customers quickly complete the replacement
