In Indonesia, power quality is often a critical issue for many manufacturing companies. The instability of the national grid, which simultaneously supplies industrial, commercial and residential users, can frequently cause:
- voltage fluctuations;
- micro-interruptions and blackouts;
- prolonged voltage instability;
- sudden voltage drops during peak load conditions.
For technologically advanced manufacturers, these are not minor inconveniences, but direct risks to production continuity, process quality and operating margins.
In this case, the customer operates two production sites in Indonesia, both equipped with numerous injection moulding machines. These machines are highly sensitive to voltage variations: even short deviations outside tolerance can lead to:
- unplanned machine stoppages;
- production waste;
- damage to electronic components and control systems;
- delivery delays;
- increased operating costs.
In an environment where grid fluctuations are frequent and unpredictable, ensuring reliable voltage stabilisation becomes a strategic priority.
THE CUSTOMER: A LEADING EUROPEAN GROUP IN THE FOOTWEAR INDUSTRY
The project involved a major German industrial group operating internationally in the footwear sector and specialising in the production of shoe lasts.
With a strong technological focus and global manufacturing presence, the company works to extremely high quality standards. The production of shoe lasts requires dimensional accuracy, process repeatability and continuous operation: even a single interruption can affect both final product quality and overall production efficiency.
The Jakarta production unit is a strategic hub for the Asian market. For this reason, the company needed a reliable long-term solution to protect its production lines from local voltage instability.
THE ORTEA SOLUTION: SIRIUS ADVANCE 1000KVA VOLTAGE STABILISER
To meet this requirement, Ortea supplied a Sirius Advance 1000-20, the top-of-the-range model in its industrial voltage stabiliser line.
This configuration is particularly suitable for environments affected by severe grid fluctuations, as it offers:
- a wide regulation range (±20%);
- high stabilisation accuracy (±0.5%);
- reliability in demanding operating conditions;
- robust mechanical design and industrial-grade components.
The Sirius Advance voltage stabiliser is designed for critical industrial applications where continuity of operation is essential.
Thanks to automatic and continuous regulation of the incoming voltage, the system ensures:
- stable power supply to injection moulding machines;
- a drastic reduction in downtime caused by under and overvoltage;
- longer service life of electronic components;
- improved production process quality.
WHY SIRIUS ADVANCE OFFERS MORE THAN A STANDARD STABILISER
Compared with the standard Sirius model, Sirius Advance includes additional features designed to further improve plant reliability and efficiency.
These include:
INTEGRATED POWER FACTOR CORRECTION UNIT
This helps optimise the power factor and reduce potential energy penalties.
TOTAL PROTECTION KIT
This increases the level of protection for the plant and sensitive loads in the event of severe grid conditions and electrical anomalies.
These features make Sirius Advance particularly suitable for industrial plants that cannot afford interruptions, process instability or premature component wear.
PRODUCTION IMPACT: PROTECTING MACHINES, QUALITY AND ROI
In the footwear sector, the production of shoe lasts requires absolute precision and repeatability. Injection moulding machines operate with electronically controlled cycles, where even a voltage variation can affect critical parameters such as:
- temperature;
- pressure;
- injection timing.
The consequences may include:
- dimensional defects;
- quality non-conformities;
- material waste;
- higher energy costs due to restarts and repeated start-up cycles.
The installation of the Sirius Advance industrial voltage stabiliser turned grid instability from a risk factor into a controlled variable, improving production predictability and protecting the return on industrial investment.
WHY CHOOSE ORTEA FOR INDUSTRIAL VOLTAGE STABILISATION
When operating in markets with unstable electrical grids, a standard product is not enough. What is needed is a partner with specific expertise in industrial power quality and international experience.
Choosing Ortea means:
- relying on technology designed for complex industrial environments;
- obtaining a solution tailored to the load and local grid issues;
- benefiting from reliability, robustness and high performance.
In scenarios such as Indonesia, industrial voltage stabilisation is not just a protective measure, but a strategic investment in continuity, quality and competitiveness.
FAQ
WHY ARE VOLTAGE VARIATIONS SO FREQUENT IN INDONESIA?
In many areas of the country, the grid may be affected by congestion and load variations, especially in urban and industrial zones. This can be compounded by uneven distribution infrastructure, complex network configurations, maintenance activities and severe weather events.
ARE INJECTION MOULDING MACHINES ESPECIALLY SENSITIVE TO VOLTAGE FLUCTUATIONS?
Yes. These machines rely on advanced electronic controls and highly precise process parameters. Even short or limited voltage variations can cause stoppages, production defects or operating anomalies.
CAN A VOLTAGE STABILISER COMPLETELY PREVENT BLACKOUTS?
No. A voltage stabiliser corrects under and overvoltage conditions, but it does not replace a UPS or energy storage system in the event of prolonged total power outages.
WHAT ECONOMIC BENEFITS CAN AN INDUSTRIAL VOLTAGE STABILISER DELIVER?
Reduced downtime, less waste, longer component life and more stable processes all have a direct impact on productivity, operating margins and competitiveness.
