Cooper Case Study: When customers in Trinidad need AJAX support, they rely on the AJAX/Waukesha COE. Over the years, we have provided complete remanufactured packages to strict offshore requirements, in-country services to re-size/overhaul packages, installed / upgraded control panels with modern Altronic instrumentation, and repaired junked/broken frames and pieces to certified “same as new” reman equipment. This support would not be complete without providing full operations and maintenance training, both classroom and hands-on, to ensure a sturdy knowledge base for their mechanical, operations, and engineering staff.
