Currently, the European manufacturing industry is facing severe pressure from high energy costs. According to the latest data from Eurostat, the average electricity cost for European manufacturing reached 0.28 euros per kWh in 2025, and even exceeded 0.35 euros per kWh in some energy-intensive regions. As a core piece of equipment that operates “24/7” in factory production, fans typically account for 18%-25% of total electricity costs, and even more than 30% in high-load workshops (e.g., automotive painting workshops and electronic component production workshops). High electricity costs have become a major “pain point” for many enterprises in cost control. How to reduce energy consumption while ensuring ventilation efficiency has become a core demand for European factory managers — and Blauberg EC smart fans are designed to solve this problem.
All series of Blauberg fans (including centrifugal fans with backward-curved impellers, centrifugal fans with forward-curved impellers, axial fans, and duct fans) are equipped with integrated intelligent EC (Electronically Commutated) motor technology. This core configuration fundamentally enables “energy consumption based on demand”. Unlike traditional fixed-speed fans that operate at full load, EC motors can dynamically adjust their speed by accurately sensing the ventilation needs of the workshop: during peak daytime production hours, when the workshop is crowded with personnel and equipment generates high heat, the fans automatically increase their speed to ensure sufficient air volume; during nighttime, when only basic ventilation or equipment heat dissipation is required, the speed decreases accordingly to avoid energy waste. Tests have shown that Blauberg EC fans can achieve an energy-saving rate of approximately 35% solely through this “intelligent speed regulation” technology. Additionally, for scenarios with high requirements for power grid stability (e.g., data centers and precision electronics workshops), Blauberg offers an optional Power Factor Correction (PFC) function, which can increase the power factor (λ) to over 96%. This effectively reduces power grid losses and avoids additional electricity fines caused by substandard power factors, further lowering electricity costs.
In terms of practical application effects, Blauberg EC smart fans have helped many European factories achieve significant cost savings. Take an automotive component processing plant in Bavaria, Germany, for example: the plant previously used 8 traditional fixed-speed centrifugal fans (each with a power of 5.5kW), operating 20 hours a day, with a monthly electricity cost of approximately 12,000 euros. In early 2024, the plant replaced all its fans with Blauberg centrifugal EC fans with backward-curved impellers (equipped with the PFC function). Operational data showed that the average speed of the fans decreased by 28% compared to before, and the monthly electricity cost dropped directly to 9,000 euros — a monthly savings of 3,000 euros and an annual electricity cost savings of 36,000 euros. More notably, the investment cost of these fans can be fully recovered through electricity savings in just 8 months. In the long run, this not only reduces operating costs but also improves the factory’s energy efficiency, aligning with Europe’s “carbon neutrality” policy direction.
For European factories struggling with high energy costs, Blauberg also provides a “personalized energy savings calculation service”. You only need to provide basic information such as the power of your existing fans, daily operating hours, and workshop ventilation requirements, and Blauberg’s technical team will generate a Personalized Energy Savings Calculation Report using a professional calculation model. This report clearly presents key data such as the expected energy-saving rate, monthly electricity cost savings, and investment payback period after replacing with Blauberg EC fans, helping you intuitively assess the feasibility of energy-saving retrofits. Additionally, if fan faults occur during use, Blauberg’s technical team can conduct remote meetings to troubleshoot issues with the factory’s maintenance personnel — by checking the equipment’s operating status and analyzing parameter data via video calls, they can quickly identify the cause of the fault. If the fault cannot be resolved remotely, Blauberg will also provide a “direct replacement with new units” service to ensure that factory production is not affected by prolonged downtime.
