ChartWater™ and Calgon Carbon Announce Referral Agreement

Pittsburgh, Pennsylvania, June 09, 2022 (GLOBE NEWSWIRE) — ChartWater a division of Chart Industries, Inc. ("Chart") (NYSE: GTLS), and Calgon Carbon Corporation ("Calgon Carbon"), a wholly owned subsidiary of Kuraray Co., Ltd. (TYO: 3405) ("Kuraray"), today formally announced an agreement signed in 2021 to jointly offer drinking water systems, using granular activated carbon, to under–resourced rural areas.

The terms of the Agreement allow Calgon Carbon to refer all communities in the United States requiring treatment of up to approximately 175 gallons per minute to ChartWater's AdEdge Water Technologies (AdEdge ), who will source all related GAC from Calgon Carbon. While both companies will continue to provide water treatment solutions for all flow rates, the Agreement enables the Companies to combine their capabilities for solutions that will cost–effectively provide safe drinking water to communities.

According to the U.S. EPA's Safe Drinking Water Act, there are over 140,000 small drinking water systems in the United States. Many of these systems face challenges in meeting ever–changing and stringent regulations around drinking water contamination, making it difficult to provide consistently safe drinking water to customers. The new Agreement offers these small systems access to AdEdge's variety of equipment offerings as well as Calgon Carbon's premium product line, FILTRASORB GAC.

"We are excited to partner with Calgon Carbon to combine their decades of GAC experience with our experience providing complete, packaged treatment systems to municipalities around the United States," said Chris Milligan, President of ChartWater. "ChartWater's AdEdge Center of Excellence provides solutions for municipal and industrial customers of all sizes. This relationship with Calgon Carbon will specifically strengthen our ability to serve smaller utilities with a world–class GAC solution for the removal of PFAS, TOC, disinfection byproducts, and any other contaminants that can be addressed with GAC."

Since creating the first activated carbon products from bituminous coal in the 1940s, Calgon Carbon has been a pioneer in developing high performing granular activated carbon products for water purification.

"Calgon Carbon has provided GAC to hundreds of water suppliers for over 40 years, and we are enthusiastic about this Agreement," said Nora Stockhausen, VP of the Drinking Water Solutions and Innovative Carbon Technologies business unit. "This collaboration allows our FILTRASORB GAC to be more accessible to smaller utilities through AdEdge's reach in this market and we're proud to work together to provide clean, safe drinking water to more Americans."
