The Complete Purging System
The NEPS1000 PUMPED is designed to maximise the dry gas purging process for humidity removal. A host of capabilities and functionality for effective and efficient control during the purging operation.
Easy Operation
NEPS1000 PUMPED is fully self-contained. Simply connect the equipment to be processed to the purge connection and the NEPS1000 PUMPED is ready to operate.
Economic Gas Use
One of the NEPS1000 PUMPED benefits is its use of the purge gas used for purging. By using a single pipe connection the purge gas is controlled and dispersed throughout the instrument or system being purged. During the depressurisation phase of purging the purge gas is isolated.
User Friendly
The NEPS1000 PUMPED has easy to use selectable programming which can be set to view process control values and display dewpoint measurements in °C or °F with pressure in Kpa or psi. Highly visible liquid displays provide constant information and readouts during the operation and use of the NEPS1000 PUMPED.
Equipment Leak Testing
The NEPS1000 PUMPED comes with a selection of four in built leak testing capabilities to verify the sealing standard of the equipment to be purged. Pressure testing can be conducted at pressures from 10.3 Kpa (1.5 psi) to 34.4 Kpa (5.0 psi). Pressure leakrate display resolution is 0.01 psi.
Gas Quality Testing
The dryness of the gas is important to the effectiveness of the purging operation and the NEPS1000 PUMPED dewpoint monitor can be used to check the dryness of the gas prior to commencing the purging operation.
Universal Voltage
The NEPS1000 PUMPED can be operated from global country voltages and frequencies ranging from 100 to 230 VAC at 50-60 Hz. There is also a 24VDC version available.
Single Point Purging
Traditional conditioning with dry nitrogen, gas or air depends on the flow of gas from an entry connection to an outlet port. In this mode, the gas will follow the simplest and easiest path to the outlet connection. This can often lead to “pockets” of unconditioned gas.
Using the NEPS1000 PUMPED, the mode of operation changes to a more efficient single connection purging process, which also uses a choice of three selectable pressure cycles to ensure the dry gas influences all the space volume within an equipment.
During the purge process, the NEPS1000 PUMPED monitors the pressure. When the pre-selected setting is achieved the supply gas is isolated and an internal control valve allows the gas to flow to the exhaust port where the dewpoint of the mixed air/gas is measured. The purging process then continues until the desired dewpoint protection has been achieved.
