Nitrogen Purging System 1900 Rack Mounted


The Nitrogen Purging System 1900 Rack Mounted (NEPS1900 Rack Mounted) is designed to maximise dry gas purging process for removal of humidity and oxygen inhibition. Self-contained equipment, the NEPS1900 Rack Mounted can be operated easily by simply connecting a dry gas source to the inlet connection and the equipment.

Comes with user-friendly features, this allows the settings of the NEPS1900 Rack Mounted to be easily configured to view process control values and display dewpoint measurements in Degree Celsius or Fahrenheit with pressure in Kpa or psi. It also features highly visible liquid displays to provide constant information and readouts throughout the operation.

The incorporated dewpoint monitor provides users with the dryness of the gas before the commence of the purging operation. Its dewpointstat feature allows users to determine the amount of moisture contained within the equipment and to implement an optimised gas and purging procedure for production control.

Upon removing the dewpoint sensor option, the NEPS1900 Rack Mounted will monitor the progress of the dewpoint dryness, switches off and isolating the dry gas when the selected dewpoint is met.

A data logger can be used to monitor the degradation time of the dewpoint, allowing users to calculate the water vapour transmission rate (WVTR) and to determine the rate of water removal during the initial purging phase. A highly versatile purging system, the NEPS1900 Rack Mounted can operate form global country voltages and frequencies ranging from 100 to 230 VAC at 50-60 Hz. A 24VDC version is also available.

The NEPS1900 Rack Mounted is best suited for applications that involve image intensifiers, optical instruments, thermal imaging, underwater equipment, surveillance instruments and electronic housings.
