Chongqing DeDong Machinery Company Nitrogen Generation Support Project

Industry: Automotive components; heat treatment of ductile iron crankshafts and gears.

Previous gas supply method: Liquid nitrogen supply; workpieces were prone to oxidation and decarburization in the high-temperature heat treatment environment, affecting component hardness and service life.

Equipment procured: 80 Nm³/h, 99.99% purity PSA nitrogen generation system.

Technical Advantages: Specialized carbon molecular sieves adapted to dust-laden heat treatment conditions ensure stable gas production; an optimized adsorption tower structure extends the service life of the molecular sieves; fully automated PLC control with intelligent load regulation reduces power consumption during no-load operation; multi-stage filtration delivers clean nitrogen with a low dew point to prevent workpiece defects; modular design enables unattended operation and simple maintenance, effectively preventing workpiece oxidation and decarburization, improving finished product yield, and reducing tooling wear and gas consumption costs.
