Drytech provides a range of equipment for purging of night vision/thermal devices. This range of instruments is used in a production, laboratory or field maintenance environment. The equipment can be used to nitrogen purge multiple devices at one time, retrieving data for quality assurance validation and verification of purge cycle and completion.

The NEPS1000 ADVANTAGE is the latest development for improving the effective and efficient use of dry nitrogen, which purges electronic, optical, high voltage laser systems and equipment requiring gas drying and inhibiting of oxygen. Drytech Offers a Comprehensive Range of Purging Instruments for Moisture Removal in Equipments and Systems to Prevent Condensation and Humidity Damage.

Specialist Purging Technology
The Complete Purging System
The NEPS1000 ADVANTAGE is designed to maximize the dry gas purging process for humidity removal, with a host of capabilities and functionality for effective and efficient control during the purging operation.

Easy Operation
NEPS1000 ADVANTAGE is fully self-contained. Simply connect a dry gas source to the inlet connection and the equipment port. The NEPS1000 ADVANTAGE is ready to operate.

Economic Gas Use
One of the NEPS1000 ADVANTAGE 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 ADVANTAGE has simple to use selectable programming, which can be set to view process control values and display dewpoint measurements in ºC or ºF with pressure in Kpa or psi. Highly visible liquid displays provide constant information and readouts during operation and use.

Equipment Leak Testing
The NEPS1000 ADVANTAGE 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 in 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 NEPS1000 ADVANTAGE dewpoint monitor can be used to check the dryness of the gas prior to commencing the purging operation.

Universal Voltage
The NEPS1000 ADVANTAGE can be operated from global country voltages and frequencies ranging from 100 to 230 VAC at 50-60 Hz.

Why Purge with NEPS1000
Modern systems that use printed circuit boards, wires, electronic components, rubbers and plastics in their construction will have potentially significant amounts of moisture. The amount of in built moisture is often described as “hygroscopic moisture”. This can be significant in comparison to the moisture (water vapor) contained within the air.

Single Connection 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 NEPS1000 ADVANTAGE 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.

NEPS1000 Advantage Applications
  • Optical Instruments
  • LASER Systems
  • SF6 Switch Gear
  • Printed Circuit Board Conditioning
  • Double Glazing Cavities
  • Electronic Housings
  • Workstations
  • Storage Containers
  • Surveillance Instruments
  • Underwater Equipment
  • Thermal Imaging
  • Image Intensifiers
What is dewpoint?
The temperature to which air or gas must be cooled for the formation of condensation or frost.
This means dewpoint is ideal for stating the quality control requirement for purging an instrument or enclosure.

The use of Nitrogen

Nitrogen is a stable and safe gas which fails to support combustion and has no or limited reactive capability with other elements when compared to oxygen. Nitrogen gas is widely used for nitrogen blanketing to prevent moisture adsorption and product deterioration.

NEPS1000 ADVANTAGE Dewpointstat
The Dewpointstat feature of NEPS1000 ADVANTAGE enables users to determine the amount of moisture contained within an equipment and to impleme
