ALNAT PProtective atmosphere solutions for all treatments of ferrous andnon ferrous metals
The heat treatment operation of semi-products as coils, strips, wires andfinished parts in ferrous and non ferrous metals is carried out underALNAT P Nitrogen-Hydrogen protective atmospheres solution with majorbenefits:
• N2-H2 or Ar-H2 atmosphere with very low H2O, CO2 or O2.• Large range of H2 concentration and flow-rate• Optimisation of the H2 content and total flow-rate• Upgrade of your process performance• Minimal capital expenses and maintenance• Easy installation and operation• Furnace safety management with Nitrogen

• Nitrogen is produced with either FLOXAL Apsa, an on-site cryogenic unit oris trucked and then stored outdoors in a cryogenic vessel.
• Based on the precise mixing of Nitrogen and Hydrogen, ALNAT P produces alarge range of atmosphere compositions and flow-rates.
• The high quality of those two gases gives a high purity mixture with very low H2O,CO2 or O2 contents to get a highly reducing atmosphere.
• Spiking the atmosphere with propane or natural gas allows a non decarburisingatmosphere.
• For annealing, neutral hardening, tempering, brazing and sintering• For semi-products and finished parts in ferrous and non ferrous metals• In batch-, pit-, pot-type furnaces, continuous belt, roller hearth furnaces• In vertical and horizontal vacuum furnaces for cooling• Bright annealing in bell and continuous furnaces with high content H2
atmospheres
• Engineered and designed to your specific needs• ALNAT P panel supply for multi-furnace or single furnace• Preventive and corrective Air Liquide maintenance• Consulting and training on gas handling and safety• Automatic nitrogen safety pipeline and procedures
