Beijing Compu-Tinway Technology Company Nitrogen Generation Support Project

Industry: New materials; research and production of tin-based solder powders for microelectronics and spherical metal powders for additive manufacturing.

Previous gas supply arrangement: During the metal atomisation process, molten metal is prone to oxidation upon contact with oxygen; therefore, high-purity nitrogen is required to provide inert protection throughout the entire process—from the atomisation tower and powder collection hopper to the storage silos—whilst the production line operates continuously 24 hours a day.

Equipment Procured: 150 Nm³/h PSA nitrogen generation system with 99.99% purity.

Technical Advantages: Specialised dust-resistant molecular sieves ensure long-term stable gas production; optimised adsorption tower structure reduces molecular sieve wear; fully automated dual-tower gas production via PLC, with intelligent load regulation to minimise power consumption during no-load operation; Multi-stage precision filtration produces clean nitrogen with a low dew point, preventing secondary contamination of the powder; modular design enables unattended operation and maintenance, reliably suppressing the oxidation of metal powders, ensuring powder sphericity and quality, and meeting the requirements for 24-hour continuous powder production and gas supply.
