Passive energy-saving devices are gaining traction as a potential low-maintenance solution for industrial power efficiency, with early results presented at the 3rd Asset and Performance Management (APM) Lead Conference showing savings of up to 11% on motors and 6.7% on air conditioning systems.

At the 3rd Asset and Performance Management (APM) Lead Conference, EEI Corporation’s Corporate Energy Manager Engr. Jhonsen Sales presented early results from a new passive device designed to improve power quality and reduce energy waste in facilities with high energy loads.

Speaking at the event, held July 28–30 at SPACE at One Ayala in Makati City, Sales introduced a Korean-engineered system called Iris, which integrates carbon nanotube (CNT) filters, magnetic wave energy, and spintronics—an emerging technology that controls electron spin to optimize current flow.

In tests conducted in office and commercial environments, the device achieved up to 11% energy savings on inductive loads such as motors and 6.7% on air conditioning systems, with minimal effect on resistive loads like lighting.

“These results are promising, especially for facilities with heavy inductive equipment,” said Sales. “The real value comes from better power quality and reduced energy waste.”

The device operates passively—requiring no external power, moving parts, or maintenance—and is expected to last up to 20 years. While still undergoing field validation, the system qualifies for installation under Department of Energy (DOE) guidelines, which allow non-registered energy-saving devices if reported savings remain under 20%.

This could position Iris as a low-risk option for industrial and commercial buildings seeking to cut operational costs without investing in active systems like variable frequency drives or on-site renewables.

Sales encouraged engineers to remain open to emerging solutions. “We need to stay curious. Small changes in how we manage electricity can have a big impact on long-term sustainability,” he said.

EEI’s presentation was part of a broader discussion at APM LeadCon 2025, which gathered energy professionals, plant operators, and decision-makers across Southeast Asia. This year’s theme—“Synergize: Creating Asset Value Through a Unified Approach to Finance and Plant Management”—underscored the role of engineering in aligning technical upgrades with cost efficiency and climate goals.

The conference highlighted how integrated asset strategies—including passive energy tech, finance tools, and performance-based maintenance—can help energy-intensive industries stay competitive, meet compliance standards, and advance sustainability targets.
