Proven Gas Purification Technology

The NEXUS-II has been designed to be the most efficient and customizable glovebox available on the market.

The VAC integrated inert gas purifier compactly fits entirely under the glovebox.

This purifier design is only 16” in depth and located toward the rear to allow more leg room or more space for under glovebox storage or equipment. This allows the NEXUS-II to be the ideal platform for custom integrations of cold wells, spin coaters, special heating wells and other equipment required for your research.

The NEXUS-II comes with a 7″ standard color touch screen control. A 10″ touch screen control is optional, and either choice means fast and easy access to your glovebox settings.

The NEXUS-II glovebox system comes complete with vacuum pump, gloves, shelving, glovebox pressure control, antechamber control, and glovebox purge control – just plug in the utilities and you are ready to start.

Regenerable Purification Technology

Every NEXUS-II Glovebox System comes with a single or dual column regenerable purification system with automatic circulation valves. The system also controls antechamber evacuation/refill, glovebox pressure and glovebox purge.

With a regenerable purifier, when the purifier becomes saturated with oxygen and/or moisture it may be regenerated to remove the oxygen and moisture using an automatic regeneration sequence. At the completion of the regeneration sequence, the purifier may be put online again to remove oxygen and moisture from the glovebox atmosphere.

Our dual column model allows simultaneous purification and regeneration.

All VAC inert gas purifiers will achieve < 1 ppm oxygen and moisture equilibrium.

Technical Data

Performance: < 1 ppm oxygen & moisture

Purification Capacity: Per purifier, 20 liters of O2 and 1.3 kg of H2O absorption capacity (per mfg. specs).

Regeneration: System has a completely automatic regeneration cycle.

The 7” touch screen LCD displays glovebox pressure, blower speed, analyzer levels and system status. The operator may note antechamber operation and regeneration status at a glance. An alarm panel shows any out of tolerance condition for operator acknowledgement or correction. The system interfaces to VAC oxygen and/or moisture analyzer assemblies.

Leak Certification: Helium leak check to 1 X 10-6 std cc/sec.

Safety Certification: Conforms and certified to UL Std 61010-1 and CSA Std C22.2 NO 1010.1, certified for CE conformity

Power: 110 or 220 VAC, 50 or 60 Hz, 15 amps.

System Weight: 1300 to 1700 lbs. (590 kg to 780kg)

Complete NEXUS-II system with an easy to use menu driven interface and a color, touch screen LCD color display. Built in programmed control of purifier regeneration, glovebox pressure and purging. Controls antechamber evacuation and refill with user programmed timed purge and evacuation. The system is available with optional VAC oxygen and/or moisture analyzer assemblies.

Purifier Isolation Valves: Automatic Valves

Antechamber Control: Controls evacuation/refill with antechamber mounted solenoid valves. User may program the automatic timed evacuation/refill or control the evacuation/refill manually through the touch screen. Optional control of antechamber evacuation with Pirani pressure gauge or inert gas purging. Manual evacuation and refill valving available.

Pressure Control: Controls glovebox pressure. The user may program both the high and low pressure control points. User may specify a special negative pressure only control process. The glovebox pressure and pressure control points are displayed on the touch screen. The system includes a footswitch for manual pressure control.

Over/Under Pressure Limit: Will sound built-in alarm and shutdown electrical power to all valves if glovebox exceeds user programmed over/under pressure limits.
