FROM CALCULATION TO POWER
About us
Electrical inefficiency is not a condition to be accepted, but a mathematical problem to be solved. This belief has guided our work for over 40 years. Every instance of energy loss, every micro-waste in the electrical flow, represents an opportunity for optimisation. From the very beginning, our capacitors were conceived as precision instruments: more than just components, they are intelligent interfaces between electrical systems and energy performance.
Productive architecture
In-house production is more than just an organisational choice—it’s a commitment to uncompromising quality control. At Enerlux, a capacitor is not seen as a finished product, but as the result of a rigorous research process. Every stage, from the selection of raw materials to final assembly, is carried out with meticulous precision and care.
Our laboratories function as true workshops of knowledge, where the physics of materials is constantly tested and analysed. Spectroscopic analyses of alloys, thermodynamic simulations, and stress tests replicating 20 years of intensive use are not just bureaucratic procedures but integral to our ongoing research process.
We adhere strictly to UNI CEI EN ISO/IEC 17025 standards, but for us, compliance is just the starting point, not the destination.
Our approach to sustainability
The photovoltaic system installed at our plant supplies 40% of our total energy needs, significantly reducing our reliance on the traditional electricity grid. Our capacitors are made from materials with a near-zero toxicity index, and our advanced production cycle enables us to recover and reintegrate 95% of metal waste back into the process.
At Enerlux, every decision made on the path towards sustainability is based on a rigorous technical and economic assessment. Reducing environmental impact is not seen as a compromise in performance, but a strategic opportunity to optimise and validate our solutions in real-world conditions, where the very technologies we develop actively power and support the processes that create them
INNOVATION BECOMES METHOD
From concept to service: the process behind Enerlux quality
In the world of energy efficiency, the difference between a simple supplier and a true technology partner lies in the method. At Enerlux Power, every solution is the result of a structured and proven process that transforms innovative ideas into tangible, reliable products designed to meet each customer’s specific needs with precision.
DESIGN
Every product we develop is guided by a dual objective: to deliver high performance today and ensure ease of operation and maintenance tomorrow. What sets our design philosophy apart is its holistic approach. We don’t focus solely on the individual component, but consider the broader system in which it will operate, anticipating interactions and optimising synergies between the system and its operating environment.
PRODUCTION
Our product portfolio includes a wide range of capacitors and industrial power factor correction systems for low and medium voltage applications. In addition to standard production, we have developed strong expertise in creating tailor-made solutions. These are based on in-depth technical analysis of each customer’s specific needs and translated into custom designs that precisely meet even the most complex operational requirements.
CONSTRUCTION
The distinctive value of our production lies in the fact that every construction phase is carried out entirely in Italy. Our production process is optimised not only to guarantee flawless technical performance but also to ensure that each component is designed for optimal operation and easy maintenance throughout the system’s entire life cycle. To ensure the highest quality standards and enable pre-delivery testing, all capacitor systems and capacitor banks—including high-voltage solutions—are fully assembled and tested in-house before shipment.
INTERNAL TESTING AND ACCEPTANCE
Every product undergoes a rigorous sequence of internal tests and trials, divided into specific stages. All inspections are conducted in accordance with Italian and international regulatory standards, ensuring not only product safety and reliability but also full traceability and compliance for certification purposes. Our quality control protocol includes multiple levels of verification throughout the entire production process:
• Incoming inspection of raw materials
• In-process checks during production
• Final testing of the finished product
To ensure the highest level of objectivity, we also collaborate with accredited third-party organisations, such as CESI, for independent validation.
PRE- AND AFTER-SALES SERVICE
Our customer support begins well before the sale, with an in-depth technical analysis of the specific requirements. This allows us to recommend the most suitable and effective solutions for every application. Support doesn’t end with installation. We remain at our customers’ side with timely, knowledgeable after-sales service . This approach allows us to offer more than just a product: we provide comprehensive support that positions us as strategic partners, fostering long-lasting relationships built on trust and technical expertise.
