Deep Cryogenic Treatment (DCT)

Air Liquide’s ALNAT™ DCT solution treats components through exposure to temperatures below 150 degrees Fahrenheit. Benefits of ALNAT DCT include increased resistance to wear, abrasion, pitting and spalling while reducing residual stress for a longer use life. The ALNAT DCT solution will help ensure a controlled atmosphere providing safety, efficiency and reliability.




Our ALNAT brand solutions include bulk gas supply, related gas handling equipment, and a range of services related to the generation, use and control of atmospheres. We provide process and safety audits to optimize the use of cryogenic and heat treatment furnaces and assist in troubleshooting. Additionally, we provide training to help ensure safe, smooth and efficient processes.


Our ALNAT supply solutions will help you ensure a controlled atmosphere in terms of safety, efficiency, and reliability in heat treat applications, including annealing, brazing and carburizing, and also in deep cryogenic treatments.
