Through our partnerships and program, we have access to an extensive inventory of new surplus and used components and assemblies that can not only deliver a significant cost savings, but also reduce lead time. We have a complete machine shop and manufacturing, fabrication, and assembly capabilities. We can rebuild assemblies, complete processing lines and other capital equipment at a substantially lower cost than new. In addition, we are always looking to purchase surplus and liquidated equipment. Let us bid on the equipment that you no longer want and/or need.
