Nitrogen Purging System 1000 Pumped (NEPS1000)


The Nitrogen Purging System 1000 Pumped (NEPS1000 Pumped) is a fully self-contained and portable nitrogen purging system used to maximise dry gas purging. It can be operated easily by connecting the equipment to the purge connecting the device. The purging system is also available with moisture adsorbing agent, molecular sieves and a self-contained pump, eliminating the need for additional gas supply.

Designed with user-friendly features, this NEPS1000 Pumped can be programmed to view process control values and display dewpoint measurements in Degree Celsius and Fahrenheit with pressure in Kpa or psi.

Features a selection of four in-built testing capabilities, the NEPS1000 Pumped allows verification of sealing standard of the equipment to be purged. Pressure testing can be done in pressures from 10.3 Kpa (1.5 psi) to 34.4 Kpa (5.0 psi). The pressure leak rate display solution is 0.01 psi.

The dewpoint monitor provides users with the dryness of the gas before the commence of purging operation. Featured with a dewpointstat, this allows users to determine the volume of moisture contained within the equipment and to implement an optimised gas and purging procedure for product control.

When the dewpoint sensor option is removed, the NEPS1000 Pumped will monitor the progress of the dewpoint dryings, switching off and isolating the dry gas automatically when the selected dewpoint is achieved.

A data logger can also be used for the monitoring of dewpoint degradation time, allowing users to calculate the water vapour transmission rate and determine the rate of water removal required during the initial purging phase. Highly versatile, the system can be operated from global country voltages and frequencies ranging between 100 to 230 VAC at 50-60 HZ. A 24VDC version is also available.

The NEPS1000 Pumped is suitable for applications that involve surveillance instruments, image intensifiers, thermal imaging, underwater equipment, optical instruments and electrical housings.
