Expert Service You Can Trust
Industrial Controller Repairs
At Neutronic Technologies, we specialise in the repair, refurbishment, and testing of industrial controllers for a wide range of applications and industries. Controllers are critical to automation and production, and when they fail, downtime can be costly. Our skilled engineers provide fast, cost-effective repairs, restoring your controllers to OEM standards and extending their service life.
With over 20 years of experience, we have built an extensive knowledge of how major manufacturers of controllers operate, as well as the common faults and failures that occur in industrial environments. From temperature controllers to advanced process controllers and PLCs, we’ve got the expertise and facilities to bring your systems back to life.
Our Controller Repair Capabilities
Neutronic engineers are highly experienced in repairing a wide variety of controllers, including:
Programmable Logic Controllers (PLCs) – including modern and obsolete models.
LJU Automation Controllers – official UK service and repair provider.
Temperature Controllers – precise repairs for heating, cooling, and process applications.
Process Controllers – advanced process monitoring and control systems.
Motion & Servo Controllers – precision repairs for automation and robotics.
Obsolete & Unsupported Controllers – repairs often more cost-effective than replacements.
Our Repair Process
We follow a detailed, proven process to ensure every controller repair meets the highest standards:
Inspection & Fault Diagnosis – We fault-diagnose each controller down to component level, identifying the root cause of failure.
Component Replacement – Faulty and degradable components are replaced with OEM-standard parts to extend lifespan.
Ultrasonic Cleaning & Refurbishment – Ensuring PCBs and modules are free from dust, dirt, and contaminants.
Testing & Verification – Controllers are tested in-house using specialist test rigs to simulate real-world operating conditions.
Return with Warranty – Every repair is backed by a 12-month warranty for confidence and reliability.
By proactively replacing time-sensitive and wear-prone components, we help minimise unexpected breakdowns and improve long-term reliability.
