Maintenance Matters Focus on: Plant & Asset Management 16 | Plant & Works Engineering www.pwemag.co.uk April/May 2026 Picture the scenario: your critical PLC fails, and you need a replacement. Fast. Supplier A offers a used unit at a nice discount compared to new. Supplier B offers their refurbished unit at a slightly smaller discount. Naturally, it’s tempting to pick Supplier A based on price alone. But what if Supplier B is the only one actually refurbishing to professional standards? Here’s a look at the difference between professional refurbishment and merely fixing what is obviously broken, why it always pays to go with the former – and how you can ensure you pick the right supplier every time. Common misconceptions There are still several misconceptions about refurbishment, all outdated. For example, some assume that refurbished equipment is simply used equipment with minimal improvements. This misses the fact that it now involves standardised processes, component replacement, comprehensive testing, and quality assurance protocols that transform the equipment to a likenew condition. Another misconception is that sourcing refurbished industrial electronics is difficult and unreliable compared to ordering new components. This is no longer the case. The refurbished market has matured significantly, with established specialists maintaining extensive inventories, digital platforms improving accessibility, and sophisticated supply networks ensuring availability. There is also a common belief that refurbished equipment will experience more failures and mean sacrificing warranty protection. Again, this is outdated. Properly refurbished equipment often demonstrates reliability comparable to or better than new equipment – allowing top refurbishers to offer warranties that match or even exceed those for new equipment. Beyond a quick fix The truth is that refurbished industrial electronics now encompasses a meticulous process of restoration that goes far beyond simple repairs. It is characterised by a systematic approach that involves thorough cleaning, comprehensive fault diagnosis, replacement of wear-prone components, and extensive testing before recertification. The goal of this is not fixing, but transformation. Quality refurbishment takes electronic components that have reached the end of their initial service life and revitalises them to a condition that rivals or surpasses new products in reliability and performance. As a result, partnering with knowledgeable refurbishment specialists provides you with a set of results far more valuable than a quick-fix merchant can offer. These include: Extending asset lifecycles far beyond manufacturer-suggested timeframes Avoiding costly and disruptive system-wide upgrades when only a single component has failed Maintaining operational continuity with minimal downtime Reducing environmental impact through resource conservation and waste reduction Preserving institutional knowledge about legacy systems Implementing predictive replacement strategies that prevent unexpected failure Building supply chain resilience against disruptions and shortages Meeting increasingly stringent sustainability requirements and reporting obligations Six questions to ask potential suppliers So, how do you identify quality refurbishers from the rest? Below are the six questions that maintenance managers should always ask. If a supplier answers ‘No’ to any of the below, you’ll be buying someone else’s problems. Find a supplier that replies ‘Yes’ to all six, and you’ll get electronics that work like new – in fact, often better than new. Do you carry out a comprehensive assessment? Before any refurbishment begins, the first step should always be to identify the problem. You want to ensure that your supplier undertakes comprehensive assessment first to ensure that only components that can be genuinely restored to a like-new condition proceed to the next phase. A key question to ask is how this inspection is carried out. While a detailed visual inspection will identify damage patterns, wear indicators, and modification history, customers should also be seeking suppliers that can perform advanced diagnostic testing. Suppliers that use specialised equipment can evaluate electrical performance and hidden defects with far greater accuracy, helping to determine refurbishment feasibility and establishing baseline conditions for restoration planning. Do you provide specialised cleaning? Always ensure that the supplier carries out industrial-grade cleaning. A true, non-negotiable and effective cleaning routine removes years of contamination using ultrasonic baths, specific solvents, and techniques tailored to different materials and contamination types. This isn’t cosmetic work: it reveals hidden damage, improves heat dissipation, and provides the foundation for reliable operation. Electrostatic discharge protection also ensures component safety throughout the process. Expect your supplier to be meticulous. It is one of the key differentiators that distinguishes professional refurbishment from simple washing, setting the stage for the comprehensive restoration that follows. Do you replace wear-proof components before they fail? Here’s where professional refurbishers shine: they replace wear-prone components before they stop working. Experienced technicians identify problematic parts like capacitors, relays, and cooling fans based on component age and failure data analysis. Replacement components meet or exceed original specifications, often incorporating improved materials and designs. This preventive approach enhances reliability beyond simple fixing, extending operational life significantly and addressing known weaknesses before they become problems. Therefore, always ask a potential supplier whether they replace functional-but-problematic parts, or only parts that have already failed. Do you carry out technical repairs? The best refurbishers don’t just carry out simple fixes. They are specialists, with the expertise that Why refurbishment is the best option…when done properly Wolter de Jong, Chief Operational Officer at JC-Electronics, discusses what sets professional refurbishers apart, and how you can make sure you always choose the right supplier.
