WHAT DOES IEQSY OFFER?
At IEQSY, we offer high-precision energy consulting solutions. Our IEQSY SMART systems analyze and predict invisible yet critical electrical micro-outages that can damage your facilities without you noticing.
We operate in a B2B model with industries, logistics centers, hospitals, data centers, and retail environments where energy stability is critical. Our energy auditors conduct thorough measurements and configure ad hoc solutions. This helps prevent failures, extend the lifespan of your equipment, and reduce costs associated with downtime or damage.
Unlike other energy efficiency companies, we don’t promise savings on your utility bill—we deliver durability and real performance. IEQSY stands for measurable, demonstrable, and sustainable power quality.
All our systems comply with international standards (ISO 50001, RD 56/2016, IEC 61000-4-30, EN 50160), and we provide certified technical and energy traceability. We use proprietary technology validated by entities such as EVO – IPMVP, ensuring maximum reliability in measurement and verification.
In addition, we support companies in achieving energy independence through customized strategies for generation, storage, control, and management.
