New Auto Switchover Systems Provide Continuous Supply Of Gases
Designed for Assist Gases in Laser Use,
Suited for Other High-Pressure, High-Flow Applications
February 15, 2002 -Virginia Beach, VA - A new unique series of high-pressure, high-flow gas distribution systems designed specifically for laser assist gases used for materials processing has been introduced by CONCOA.
The 639 Series Switchover is ideal for all laser assist gas systems utilizing helium, nitrogen, oxygen, and argon for connection to tube trailers, cylinder cradles, or gas packs. Advanced features include automatic switchover to reserve assist gas supply when the primary source is depleted, without pressure fluctuations, offering consistent reliability and precise system control. An optional alarm allows for visual and audio notification of the need to replace depleted cylinders.
Designed to meet the needs of varied individual assist gas system environments that include cradle to cradle, manifold to tube trailer, cradle to tube trailer, and manifold to cradle, the 639 Series Switchover is equipped with a choice of flexible pigtails for use with two gas sources or manifold connectors for use with modular manifold systems.
Constricted for high-pressure, high-flow use, bodies are made of brass barstock, seats of PTFE Teflon® and Kel-F®, filters are 40-micron sintered bronze, internal seals are PTFE Teflon® and Viton®, and weight is 124 pounds. Inlet pressure ranges from 3000 PSIG (210 BAR) to 4500 PSIG (300 BAR), delivery pressure ranges of 0-400 PSI and installed in environments with temperatures range from -40 to 140 deg F (-40 to 60 deg C).
