From Obsolete to Long-Lasting: Why Repair and Preventive Overhaul Are Often the Better Choice
In a world where devices are quickly replaced, it pays to take a second look—especially when it comes to industrial electronics. Just because a device is officially “discontinued” by the manufacturer doesn’t mean it has no future. On the contrary: with proper repair and preventive maintenance, the lifespan of such devices can be extended by 10 or even 15 years.
Why replace when you can maintain?
Many of our competitors say the same—and rightly so: with high-quality spare parts and deep technical expertise, it’s entirely possible to continue operating older devices reliably. We frequently receive units for overhaul that have impressed us—some have been running for over a decade.
More and more of our customers are turning to preventive overhauls. We increasingly come across devices that have already undergone previous repairs—often with issues. Unfortunately, some providers offer seemingly low-cost repairs but invest very little in quality, aiming only to keep the unit running until the warranty expires. Some even hope that the device will fail again soon, so they can profit a second time. That mindset is not only unethical—it’s short-sighted.
Real-World Example: The Yaskawa SGDH-50AE
Take the Yaskawa SGDH-50AE, for example: we replace over 30 components during a full overhaul. These devices can present a range of complex faults—from defective internal power supplies to failed output stages or malfunctioning encoder drivers. Many issues can arise. That’s why we take a holistic approach: we test every function block, apply load tests, and proactively refurbish all known weak points.
Such an approach is only possible because we’ve repaired this model many times before—and because our technicians bring years of hands-on experience.
Quality that pays off
Our message: When you invest in quality, you gain reliability. A proper overhaul may cost more upfront—but it saves you downtime, reduces long-term costs, and protects the environment.
Sustainability starts by maintaining what already exists—with expertise and care.
