Introduction to Condition-Based Maintenance (CBM): Concepts and Benefits

Condition-Based Maintenance (CBM) is an innovative strategy that is revolutionizing the way equipment is monitored and maintained. Unlike traditional approaches such as corrective or preventive maintenance, CBM relies on real-time monitoring of the operational conditions of systems, using sensors and advanced technologies to predict and prevent failures before they occur. This approach offers a new dimension of efficiency and predictability for supermarkets, especially in refrigeration and air conditioning systems.

The History of CBM

The origin of Condition-Based Maintenance dates back to the advancement of monitoring and industrial automation technologies in the 1960s and 1970s. During this period, the industry began adopting sensors to measure variables such as temperature and vibration in critical equipment.

Over time, the combination of more precise sensors and analysis software allowed engineers to evaluate asset performance in real-time, identifying anomalies before they turned into failures. During the 1980s and 1990s, CBM was widely adopted in sectors such as aviation, energy, and manufacturing, where equipment reliability is essential.

In recent years, the evolution of the Internet of Things (IoT) and Artificial Intelligence (AI) has made CBM even more accessible and efficient. Today, supermarkets and retailers also benefit from this approach, optimizing their refrigeration and air conditioning systems to meet modern demands for efficiency and sustainability.

What is CBM?

CBM uses real-time data to assess the condition of equipment. Strategically positioned sensors monitor variables such as temperature, pressure, vibration, and energy consumption, allowing managers to identify anomalies and make decisions based on facts, not assumptions. This practice reduces reliance on fixed maintenance schedules and minimizes the need for emergency interventions, increasing system reliability. Additionally, CBM promotes a more assertive and personalized approach for each type of equipment.

Benefits for Supermarkets

Supermarkets rely on refrigeration and air conditioning systems to ensure product preservation, customer comfort, and operational efficiency. CBM offers significant benefits that go beyond conventional maintenance:

1. 1. Energy Efficiency: Continuous monitoring identifies energy waste and optimizes equipment performance. This directly contributes to reducing operational costs and improving sustainability.
2. 2. Cost Reduction: By preventing unexpected failures, CBM significantly reduces corrective maintenance expenses and minimizes downtime. In supermarkets, this avoids financial losses related to refrigerated products that could be discarded due to system failures.
3. 3. Sustainability: Reduced energy consumption and increased equipment lifespan reinforce sustainable practices, aligning with ESG (environmental, social, and governance) goals. More efficient equipment also contributes to reducing carbon emissions.
4. 4. Increased Reliability: With constant monitoring, it is possible to act preventively before minor issues turn into critical failures. This increases system availability and reduces interruptions in supermarket operations.

Application Examples

• Refrigeration Systems: Temperature and pressure sensors monitor the central units of refrigeration systems. When significant variations are detected, technicians are immediately alerted, preventing issues such as refrigerant leaks or compressor failures.
• Air Conditioning: Vibration sensors detect wear in motors and components before significant damage occurs. This early detection allows for scheduled maintenance, reducing costs and avoiding operational interruptions.
• Energy Monitoring: Integrated systems analyze energy quality and consumption in real-time, highlighting operational inefficiencies and allowing adjustments that result in significant savings. A practical example is the detection of consumption peaks indicating system overload, allowing immediate corrections.
• Automation: The combination of sensors with automated systems allows equipment to automatically adjust its performance to meet ideal operating conditions. This ensures that resources are used more efficiently, reducing waste.

Conclusion

Implementing CBM represents a strategic advancement for supermarkets looking to reduce costs, increase energy efficiency, and adopt sustainable practices. By continuously monitoring the operational conditions of refrigeration and air conditioning systems, it is possible to make proactive decisions that ensure more efficient and reliable operations. Additionally, this approach improves maintenance predictability, reducing unpleasant surprises.
