Gränges Americas Improves Molten Metal Quality with Almex USA LARS® Degassing and Purification Systems

Almex LARS RL-2 Model

Buena Park, California, USA – October 2019 – Almex USA Inc. has successfully commissioned four LARS® Degassing and Purification Systems for Gränges Americas Inc., a wholly owned subsidiary of Gränges AB, the world’s largest manufacturer of rolled products for heat exchanger industries. One pair of LARS® systems were installed at Gränges’ plant in Huntingdon, Tennessee on the company’s twin-roll sheet casting lines, and two more were installed at the Salisbury, North Carolina facility. Both locations are a part of Gränges AB’s 2016 acquisition of the former Noranda Aluminum’s rolling business, and currently produce 1xxx, 3xxx, and 5xxx series alloys for end-product applications in HVAC, packaging, and electrical transformers.

The custom-designed Almex LARS® RL-2 model incorporates a uniquely designed reaction chamber, two-rotor gastrain system, and Almex’s proprietary electrical heating system for metal temperature control. The supply is complete with PLC & HMI Control systems and outfitted with Inert Gas and Halogen Gas Administration systems built to the rigorous UL508A industrial control panel standards. Almex’s comprehensive knowledge and proven track record in melt treatment and purification, coupled with the LARS® system’s unique performance inclusive of finished product warranties, were said to have been the deciding factors in the selection of Almex USA as Gränges’ equipment and technology supplier.
