Vestfold, Norway – A major building materials factory in Vestfold, Norway, has recently upgraded its backup power system by deploying a WANGA 250kVA silent canopy diesel generator set (Model DC275W-50S) to address significant operational risks caused by sudden power outages. The factory specializes in producing mineral wool boards, calcium silicate boards, cement pressure boards, and other building materials, with production lines requiring extremely high power continuity. Any power interruption could lead to prolonged restart times and raw material spoilage. The WANGA unit, with its silent design and rapid response capability, ensures uninterrupted operation of critical equipment during grid failures, providing high-reliability power assurance.
01 Project Background and Industry Challenges
The Vestfold region in Norway is a core area for the building materials industry. This factory operates multiple automated production lines, including energy-intensive processes such as calcium silicate board forming and gypsum board drying. Equipment like compressors (approx. 50kW per unit), drying ovens (100kW), and automated control systems are highly sensitive to voltage fluctuations. A power outage would not only cause semi-finished product solidification and scrap but also require several hours to restart the production line, with potential daily losses reaching tens of thousands of euros.
- Load Level Requirements: According to industrial power standards, such continuous production lines are classified as Level-1 loads, requiring dual power sources or self-contained backup power assurance.
- Geographical and Environmental Factors: Norway's severe winter weather can lead to grid interruptions; the backup power source must possess cold-start capability.
- Environmental Requirements: The factory is located in an area with strict European environmental regulations, requiring equipment to meet low-noise (≤75dB) and low-emission standards.

Power Adjustment Recommendations:
- Current Configuration Issue: The 250kVA set has a rated output of approximately 200kW, while the factory's peak demand reaches 495kW, posing a high risk of severe overload.
- Optimization Solution: It is recommended to upgrade to a 500kVA unit (Model DC550W-50S), with a rated output of 400kW, providing 20% redundancy to cover inrush currents and support future production capacity expansion.
03 Technical Solutions and Functional Enhancements
Targeted improvements of the WANGA DC275W-50S unit:
- Rapid Load Acceptance: Added single-step load acceptance of 70% (175kW), ensuring critical loads are assumed within 10 seconds to prevent control system crashes due to voltage dips.
- Silent and Eco-Friendly Upgrades: The canopy uses multi-layer sound-absorbing materials, controlling noise below 75dB at 7 meters; emissions comply with EU Stage V standards, aligning with Norway's carbon reduction policies.
- Intelligent Monitoring System: Integrated remote management module allows factory maintenance staff to monitor voltage, frequency, and fuel status in real-time via a mobile APP, with automatic fault alerts.
- Low-Temperature Adaptability: The engine is equipped with a preheating system, supporting quick starts in -30℃ environments to cope with Nordic severe cold climates.
04 Demonstration Significance for Industrial Energy Security in Northern Europe
This project sets a new benchmark for backup power in manufacturing industries in cold Nordic regions:
- Reliability Standard: Rapid response (≤10 seconds) and cold-start capability become benchmarks for industrial backup power.
- Sustainability: The unit's compatibility with biodiesel aligns with Norway's 2030 renewable energy goals.
- Policy Reference: The EU's "Industrial Power Resilience Guidelines" are promoting the adoption of similar solutions in critical sectors like building materials and chemicals.
Conclusion: The WANGA 250kVA unit enhances the factory's power resilience through silent and intelligent design. However, to match the actual load, an upgrade to a 500kVA unit is recommended. This case highlights the core value of customized backup power in ensuring the continuity of European manufacturing supply chains.
