Thailand Palm Oil Mill Energy Monitoring & Predictive Maintenance
Introduction
This customer is a palm oil producer in Thailand specializing in palm kernel oil extraction. Rich in fatty acids, palm kernel oil is widely used in products such as edible oils, biodiesel, cosmetics, and other industrial applications.
Operating a palm oil processing facility in Thailand’s tropical climate presents several challenges. Manual feed monitoring is labor-intensive, maintenance scheduling can be difficult, and equipment performance must be closely managed to avoid downtime. To address these issues and support the company’s transition toward smart manufacturing, ICP DAS USA implemented a solution focused on four key objectives:
Challenges Faced by Plant Operators
A typical palm oil milling machine consists of a storage hopper, oil pressing screw, and drive motor. During operation, workers must continually monitor and regulate the flow of palm kernels entering the machine.
When excessive material enters the system, sticky residue can accumulate on the screw, slowing production and increasing motor load. As a result, energy consumption rises significantly, requiring operators to manually redistribute the material to maintain smooth operation.
These conditions can lead to:
The demanding work environment, combined with reliance on manual supervision, created ongoing operational and safety concerns for plant management.
A Practical Path to Smart Manufacturing
As a new generation of leaders took over the family business, they recognized the value of adopting smart manufacturing technologies to improve efficiency and competitiveness.
However, many available solutions were either overly complex or too costly for their operational requirements. After conducting a detailed site assessment, ICP DAS USA developed a cost-effective solution that combined energy monitoring and equipment condition monitoring in a single platform, providing a practical first step toward digital transformation.
ICP DAS USA Solution for Energy and Equipment Monitoring
Hardware Architecture
As shown in the system architecture (Figure 1), ICP DAS USA’s PM-3133-360P three-phase smart power meters were installed to continuously measure the energy consumption of the oil expeller motors.
The meters were connected to the motors’ voltage and current circuits to collect accurate real-time electrical data. Using Modbus RTU communication, the smart meters transmit data to the PMC-5231M power meter concentrator.
The PMC-5231M aggregates, stores, and processes the collected energy data before forwarding it to the SCADA system via Modbus TCP. This centralized approach enables operators to monitor power usage, identify abnormal equipment behavior, and make data-driven maintenance decisions that help reduce downtime and improve operational efficiency.
Predictive Maintenance (PdM)
The energy monitoring system helps operators assess material feeding conditions by tracking motor current and power consumption through an intuitive SCADA interface (Figure 2). Clear visualization of operating status, including idle, normal-load, and high-load conditions, makes equipment performance easy to understand.
When a machine operates under frequent or prolonged high-load conditions, the system alerts plant personnel to potential issues before they lead to failures. This enables maintenance teams to schedule service proactively, helping reduce unplanned downtime, extend equipment life, and improve overall production efficiency.

Features and Benefits of the ICP DAS USA Solution
Increased Production Capacity
By implementing ICP DAS USA smart power meters, the palm oil mill increased production capacity by 28% annually, helping improve overall operational performance and throughput.
Data Visualization
Previously, equipment monitoring was performed manually. With ICP DAS USA’s energy monitoring solution, power consumption data is displayed through intuitive dashboards, giving operators clear, real-time visibility into machine performance and energy usage.
Predictive Maintenance with IIoT
Real-time data visualization helps reduce guesswork and enables operators to identify abnormal operating conditions early. Maintenance can be scheduled based on actual equipment performance, reducing maintenance costs and minimizing the risk of unexpected machine failures.
Automated Alarm Notifications
The PMC-5231M power meter concentrator features built-in IF-THEN-ELSE logic and optional alarm notifications via email or LINE. If a machine stops unexpectedly or operates outside normal conditions, the system automatically sends alerts, allowing supervisors to respond quickly and reduce downtime.
Real-Time and Historical Energy Analysis
The PMC-5231M collects both real-time and historical power data, enabling operators to monitor equipment performance, analyze energy consumption trends, and identify opportunities to improve efficiency and reduce utility costs.
Reliable Data Logging
The PMC-5231M includes data logging capabilities that help protect critical energy records. Even during network interruptions or storage media issues, the system continues operating and preserves data integrity, minimizing the risk of data loss.
Conclusion
As industrial facilities continue adopting IIoT and smart manufacturing technologies, ICP DAS USA helps customers transform operational data into actionable insights. By combining intelligent power monitoring with SCADA-based visualization, organizations gain a centralized view of equipment performance, energy consumption, and maintenance needs.
For this Thailand palm oil mill, ICP DAS USA delivered a cost-effective solution that addressed key operational challenges while increasing production capacity by 28% annually. The system provides far more than energy monitoring alone. It supports cost reduction, energy efficiency, electrical safety, and predictive maintenance, helping improve reliability, increase workplace safety, reduce downtime, and maximize operational profitability.
