Linde LLC's Hydroflex atmosphere control system (ACS) is a solution for clean and bright oxide-free annealing of steel, stainless steel, copper, bronze or brass with high reliability and repeatability and is suitable for applications including automotive, aerospace and military components, construction and industrial equipment and electrical systems. According to the company, the system can use one or more carrier gases—nitrogen (N2) or argon—to maintain the furnace pressure while a controlled ratio of hydrogen (H2) helps prevent oxidation. With this technology, many annealing tasks can be completed with non-flammable gas mixtures containing less than 5% H2, which contributes to fire safety while optimizing the use of H2 in the process. Features and benefits of Hydroflex ACS include precisely controlled atmosphere, improved heat transfer, uniform heat distribution, faster cooling rate, automatic safety purging with N2 and storage of process data history.
