The single point purge of the NEPS 1000 is superior to a standard two point purge as it uses the nitrogen, or dry gas, more efficiently, thereby purging the equipment more quickly and sparing the additional expense of wasted gas. The single point feature of the NEPS 1000 also provides a dew point temperature measurement for the gas stream leaving the equipment.
Yes. It is available in a 19″ rack mounted version (“NEPS 1900 Racked“) for use in automated test situations.
The NEPS 1000 comes standard with male and female quick disconnect. The female will need to be adapted to your nitrogen line and has a 1/4″ NPT female thread to connect to.
The standard NEPS 1000 and NEPS 1900 Rack Mount models require nitrogen or other dry air source. The “NEPS 1000 Pumped” has a bed of molecular sieve desiccant that dries the incoming air prior to sending it into your enclosure, and does not require a dry air source. This is particularly useful in field use where it might be cumbersome to have a bottle of high pressure nitrogen on hand. However, periodically, the molecular sieve desiccant will need to be replaced. AGM carries a full line of desiccant products and can supply replacement desiccant for NEPS units.
No. The NEPS 1000 can be used with nitrogen, dry air, argon, and SF6 gases. It should be noted that dry gases are available in varying qualities and levels of dryness. (No flammable gases should be used)
The NEPS will display a dew point range of +20°C (+68°F) to -80°C (-112°F).
No. After initial setup, the NEPS 1000 will automatically stop the dry gas cycling when the air stream leaving the equipment reaches a preset dew point temperature. With the addition of a remote sensor, the dew point stat feature of the NEPS 1000 will then resume dry gas cycling after the dew point temperature has degraded to a predetermined amount.
Yes. After repeated cycles it will become apparent when the moisture has been removed from the hygroscopic materials in the equipment. It is a common misconception that the majority of the moisture in sealed equipment is contained in the empty volume of air. In fact, the majority of the moisture is contained in the hygroscopic materials, such as electrical boards and plastic components.
Yes. You can lease a NEPS unit so you can test it for your specific applications, contact AGM for more information.
