NEW HIGH-PURITY GAS SWITCHOVER SYSTEM PROVIDES CONTINUOUS SUPPLY

May 18, 2015 - Virginia Beach, VA - A highly accurate, reliable gas distribution system that automatically switches between two high-pressure gas sources to enable uninterrupted supply in challenging applications has been introduced by AURA Controls, the world leader in pressure and process control technologies.

The AURA EXD series automatic differential pressure switchover system is designed to provide a continuous supply of high-purity gas in critical applications and demanding process environments. The EXD is an ideal fit for carrier and calibration gas delivery applications used in chromatography processes, sampling systems, and laboratory instrumentation.

The proven switching technology provides fail-safe operation utilizing a priority valve assembly, allowing the end-user to replace depleted gas containers without system interruption and increasing the amount of time between change-outs. The proprietary switching technology also allows for maximizing cylinder economy and flow rate by drawing more gas from each container and increasing flow without depleting both containers simultaneously.

The EXD’s fully configurable inlets provide flexibility to properly fit application-specific requirements for fittings, purges, and isolation valves for inlet pressures up to 3000 psig. Available in delivery ranges up to 350 psig with 4”, 12” and 24” panel options, AURA EXD regulators are assembled in a Class 100 cleanroom while the entire system is 100% helium- leak checked and cleaned for oxygen service.
