When retrofits are planned and implemented on a sound basis, older machines can be equipped with the latest electtical, control and safety technology. The costs are considerably less than buying new. The retrofit not only makes the machine safe again, but also increase its productivity and availabilty. If production is back running efficiency and smoothly, then the retrofit pays for itself in no time.
Increase your productivity significantly by upgrading your machinery to the state of the art. You need to do this because safety defects can develop on plant and machinery after many years of service. For example, protective measures may become obselete and be manipulated. The control and drive technology is often outdate while the mechanical components are still fully intact. http://www.pilz.com
