Praxair to supply Bridgelux with ammonia and high-purity hydrogen

Praxair Electronics (a division of gas company Praxair Inc of Danbury, CT, USA) has been selected by solid-state lighting firm Bridgelux Inc to supply its gallium nitride (GaN)-based LED design and manufacturing center in Livermore, CA with ammonia and high-purity hydrogen.

Praxair has installed its ammonia-delivery system, equipped with SureFlow control technology and a patented heat-control design, at Bridgelux’s Livermore facility. Bridgelux chose Praxair’s 10-metric-ton ISO container, configured for vapor-phase delivery of the ammonia, which is inherently safer to operate than liquid draw systems, says Praxair. The high-capacity bulk system can deliver sustained ammonia flow rates more than 2000 standard liters per minute, with a peak flow capacity over 3000slm.

Praxair says that its system features full equipment monitoring to ensure reliable process control and eliminates the need for a large number of cylinder change-outs, reducing costs and improving safety and reliability.

“Praxair has been an important partner in the expansion of Bridgelux’s manufacturing operations,” says Bridgelux VP of manufacturing Mike Peanasky. “As Bridgelux continues to drive product performance and technical innovation in solid-state lighting, the high-quality Praxair products are instrumental to those efforts,” he adds.

“Repeat selection by Bridgelux of our high-purity ammonia and gas delivery technologies [after ordering a 600slm system last December], and Bridgelux’s adoption of our high-purity hydrogen system, underscores Praxair's position as a premier supplier to the LED and electronics market,” comments Praxair Electronics’ president Mark Murphy.
