Improved performance in vacuum metallurgy

Vacuum pumps are widely used in heat treatment furnaces and thermal processing to generate the optimum environment for the hardening or softening of metals and to ensure the material surface stays free from oxidation. In today’s economic climate manufacturers are under increased pressure to reduce both their manufacturing cost and their environmental footprint. Recent developments in vacuum pumps have resulted in more environmentally friendly products that address these requirements. The latest ranges of industrial dry vacuum pump technology provide opportunities for major energy savings in heat treatment furnaces operations, and set new standards in operating efficiency and ease of integration into control systems. This article examines these features and benefits throughout some real case studies.
