Nitrogen Purging Methods |
|
| NITROGEN PURGING: THE OLD METHOD - INADEQUATE PROTECTION | |||
| When equipment is dehumidified by a method which is not monitored, the result is questionable. |
|||
| The image to the left illustrates the flow path of nitrogen gas through equipment when connected in the normal way. When using this method of purging, the gas will always take the path of least resistance and, therefore, not purge thoroughly. | |||
| NITROGEN PURGING: THE NEPS METHOD - EFFECTIVE PROTECTION | |||
When equipment is dehumidified with a NEPS 1000, it is pressurized up to 5 psi before the gas is vented to atmosphere. |
|||
The image to the left illustrates how effectively the NEPS 1000 Advantage can control the purging process. By introducing nitrogen under pressure, every part of the equipment is purged before the gas is allowed to flow back into the NEPS 1000 Advantage. The exhaust gas is passed over a dew point sensor to monitor the moisture content and the dew point reading is then displayed on the front of the NEPS 1000 Advantage. Finally, the nitrogen is vented to the atmosphere and a new cycle commences. This procedure continues until the equipment reaches the required dew point level. |
