Protect systems and equipment from high humidity and water vapour using nitrogen purging systems. Nitrogen-enhanced purging system 1000 pumped (NEPS1000) is a portable purging system for equipment with electronics, optical instruments, thermal imaging, electronic housing laser systems, underwater equipment, and surveillance instruments.

The purging unit includes a self-contained pump filled with molecular sieves without requiring an additional gas supply for humidity removal. Use a single connection to control the purge gas dispersed throughout the equipment.

Using highly visible liquid, the unit can provide a constant data display to view process control values and dew point measurements. Gas quality and leak testing can be conducted using the system before starting the purging operation.

Operating from voltages ranging from 100 – 230 VAC at 50-60 Hz, connect the equipment to the purge connection and select from the three pressure cycles to ensure that dry gas is purged within all the space within the instrument. During the purging, the unit will monitor the pressure while allowing internal gas to flow to an exhaust port for dewpoint monitoring. The purging process will automatically stop upon reaching the desired dewpoint protection point.
