The 34,000 square foot workshop is fully equipped for the repair and refurbishment of all large rotating machines. Additionally, it houses a highly skilled team of electro-mechanics, winders, engineers, and technicians, all of whom have extensive knowledge and experience in large motor and generator repair and refurbishment, and a support team of quality control, health and safety, procurement, administrative, and logistics specialists. With this equipment and team of experts, Renown Electric is well placed to deliver high-quality repair and refurbishment services for electrical rotating machines.
