ASB Industries, Barberton, Ohio, announces that it has replaced older technology and upgraded its cold spray system with a new Messer/Linde high-pressure nitrogen pump, the Presus N10.
Critical particle velocity is required for physical build-up of cold-spray coatings and additive manufacturing. Unlike thermal spray processes, cold-spray materials in powder form with different densities require stable high-pressure nitrogen for bonding and interparticle adhesion. PLC controls throughout the system, along with high-pressure rated valves and piping, are required during cold spraying for both production projects and critical material and application development.
Linde Corporation provided installation in conjunction with safety checks. The system is located adjacent to the Cold Spray process area that utilizes the Impact Innovations 5/11 System, with an ABB robot and five-ton crane capabilities.
The following is taken directly from Messer/Linde published data:
The Presus N10 liquid pump is an energy-efficient unit that delivers nitrogen at high pressure. No degradation of gas purity takes place while liquid nitrogen is gasified.
The Presus N10 pressurizes liquid nitrogen by a hydraulically-operated, slow-moving piston before evaporation. Therefore, the liquid pump is a updated technology for industrial processes such as gas assist cold spray, injection molding, laser-beam cutting, or other processes where high-pressure gases are necessary.
Energy consumption is up to 90% less than gas compression units, and the flow rate is at least five times higher than gas compressors.
