Praxair has signed a long-term agreement to build, own and operate an air separation plant that will supply 700 tonnes per day of nitrogen (N2) to Samsung’s display manufacturing complex in Tangjeong, South Korea.

The complex is the largest sixth-generation flexible Organic Light Emitting Diodes (OLED) panel plant in the world. Its capacity is increasing in 2017 in order to meet global market demand. OLEDs are used in variety of products including televisions, mobile devices, digital cameras, virtual reality headsets and laptops.

This will be Praxair’s fourth air separation plant supporting the facility and it is expected to start up in 2018. This additional N2 will be used for cooling and purging applications in Samsung’s manufacturing process.

Praxair Korea’s President, B.S Sung, enthused, “We are proud to expand our longstanding relationship with Samsung and help support their growth globally. Through the years, our customer service teams and engineers have worked closely with Samsung on new ways to improve productivity and develop innovative applications technologies while continuing to provide a reliable supply of gases to their operations. We look forward to building on our relationship in the future.”

Praxair has provided a reliable supply of N2, oxygen, argon, helium and other gases to many of Samsung’s operations, including the Tangjeong LCD factory, for more than 25 years.
