Frequently Asked Questions

Denka® is a patented energy-optimization plate installed on electrical panels to reduce conducted electromagnetic noise, improve power quality, and lower electricity consumption in commercial, industrial, and residential facilities.

Denka® is not a capacitor bank, not a voltage stabilizer, and not a cheap plug-in "power saver." It uses advanced ferrite-based materials to reduce high-frequency conducted emissions on power lines, which leads to lower system losses and improved efficiency across your installation.

Denka® was developed by a team of electrical engineers, materials engineers, and scientists over more than five years of R&D, lab testing, and field validation before commercial rollout in 2019.

Denka® has been installed in supermarkets, factories, offices, showrooms, EV charging stations, restaurants, schools, and residential buildings in multiple countries.

Denka® is a one-time hardware installation. The plates are passive components with no moving parts and are designed for long-term operation without regular replacement.

Yes. The technology is scalable. A small shop may use a few plates; a large facility may require multiple sets across main and sub-panels.

Denka® reduces high-frequency electrical noise (conducted emissions) on power lines, typically in the range of tens or hundreds of kilohertz up to several megahertz. This noise increases losses in cables, transformers, power supplies, and electronic loads. By mitigating this noise, Denka® helps the system operate more efficiently, which translates into measurable energy savings.

You can think of Denka® as a specialized passive filter using advanced ceramic materials. However, it is not a traditional LC filter or harmonic filter; it targets a specific band of conducted emissions that most standard power equipment does not address.

No. Denka® does not alter the nominal voltage or frequency of your electrical supply. It works on the noise components riding on top of the normal waveform.

Denka® is not primarily a power factor correction device. In some installations, a slight improvement in power factor may be observed as a side-effect of reduced noise and cleaner waveforms, but it should not be used as a replacement for traditional power factor correction where that is required.

Denka® is a passive solution based on engineered ceramic materials—no active electronics, no external power supply, no communication modules.

Skepticism is healthy. Denka® is backed by lab measurements, long-term field projects, and savings verification according to recognized energy measurement protocols. We openly share our methodology and invite technical review by your engineering or energy management team.

Denka® plates are typically installed inside sub-panels that provide the electrical loads directly, and it must cover the whole facility.

Installation must be performed by qualified electricians or engineers familiar with local electrical codes. Denka® provides guidelines, drawings, and remote support, and can offer on-site support in certain countries.

For a typical commercial panel, installation takes from 5 minutes to 30 minutes per panel, usually needs no shutdown unless the facility policy forced so which avoids disrupting operations.

In most cases no, the panel needs to be opened and work performed near live conductors. Shutdown planning is only required as a part of the installation process for panels that cuts power when opened for safety reasons.

Usually no major modifications are needed. Denka® plates are designed to be mounted inside existing panels, using available space and following safety clearances.

No. Denka® is installed in parallel with your existing system. No re-wiring of loads or major breakers is required, except for the connections needed to mount and bond the plates correctly.

Under normal conditions Denka® is maintenance-free. During routine panel inspections, technicians can visually check that plates remain securely mounted and undamaged.

Typical installations report savings in the 8–20% range on the electricity consumption of the circuits where Denka® is applied. Actual results depend on your load mix, operating hours, power quality, and installation quality.

In many commercial and industrial projects, payback can range from less than one year to a 1-Year Max guaranteed by Denka®, depending on local electricity tariffs, load profile, and scale of installation.

We do not promise a fixed percentage for every site, because each facility is different. Instead, we propose a measured and verified approach before and after installation, using transparent methodology and customer-side meters ensuring a money back guarantee if the promised minimum 8% is not achieved.

Savings are evaluated using recognized energy measurement protocols (such as IPMVP® Option C), combining power analyzer data, historical consumption, and operational conditions (production levels, occupancy, temperature, etc.).

The nano-crystalline built & ceramic-based materials used in Denka® are stable under normal operating temperature and electrical conditions. Significant performance degradation over time is not expected if installation guidelines are followed. Denka® lives up to 60 Years at same efficiency.

Yes. The effect on conducted emissions is immediate once Denka® is energized. However, to see the impact on your energy bills clearly, you should compare data over 30~90 days to account for normal operational variations. And to help IPMVP® Analysis with enough data for the best accuracy.

Yes. Denka® is a passive device with no active electronics. It is installed according to standard electrical safety practices and does not introduce additional risk if properly mounted by qualified personnel.

No. Denka® is designed to reduce harmful high-frequency noise and improve overall power quality. It does not inject power into the system or distort the main waveform.

Denka® is designed and tested according to relevant electrical safety and EMC (electromagnetic compatibility) concepts. It is installed as an accessory to your existing system and does not change your supply parameters. Following the IEC CISPR11 & CISPR32 Standards.

Since Denka® is a passive accessory that does not alter voltage or frequency, it is generally not a reason to void warranties. However, every manufacturer has its own policies, so we recommend informing your major equipment suppliers if needed.

Yes, provided that proper engineering review is done. In many sensitive sites, improving power quality and reducing noise can be especially beneficial for electronics and control systems.

Facilities with a high share of electronic and non-linear loads—such as variable-speed drives, refrigeration compressors, HVAC equipment, LED lighting, IT equipment, and EV chargers—often see the strongest benefits.

Yes. Denka® can be installed in facilities with grid-tied solar PV systems to help optimize overall power quality. The exact placement relative to inverters and main panels is determined during the engineering review.

Yes. EV chargers introduce high-frequency emissions and rapid load changes. Denka® helps reduce noise and losses in such systems and can contribute to better overall efficiency and stability.

Yes. Denka® can be applied to large villas and residential buildings, especially where there are many electronic devices, pumps, elevators, or home solar systems. For small apartments, a technical and economic assessment is made first.

Denka® can be configured for use in both three-phase and single-phase systems, subject to design and installation review.

In principle yes, the plates are detachable and can be re-installed elsewhere by a qualified electrician. However, each new site requires a fresh technical assessment.

We typically use IPMVP® Protocol - Option C - Please review it on Evo's website.

Yes. For project-based installations, Denka® provide a formal analysis report showing baseline vs. post-installation performance, methodology, assumptions, and calculated savings.

Denka® itself is a passive device, but measurements can be taken from your existing meters and EMS. In some projects, Denka® is combined with EMS software to continuously monitor performance and provide dashboards.

For serious projects, we recommend at least 12–24 months of baseline data and 2–3 months of post-installation data.

By reducing energy losses and consumption, Denka® helps lower CO₂ emissions associated with electricity generation. It also contributes to longer equipment life by improving power quality, which reduces waste from premature failures.

Denka® plates consist mainly of engineered ceramics and metal components. At end of life, they can be handled according to local regulations for metal and electronic accessories. We encourage responsible recycling practices.

Denka® does not generate new fields; it interacts with existing high-frequency noise on the lines to reduce it. It does not emit RF signals or wireless communication.

Denka® is designed to act on high-frequency conducted emissions typically in the hundreds of kilohertz up to several megahertz range, which are often generated by modern switching power electronics.

Its primary action is on higher-frequency components above the classical harmonic range. However, by reducing noise and improving the behavior of some power electronics, observable changes in THD can occur in some installations.

Yes. We can share selected lab measurement summaries and project case studies under NDA or as part of a technical evaluation.

The number of plates depends on how many SMDBs and each panel capacity, load type, and configuration. Our engineering team or local partner will review your single-line diagrams and consumption data to recommend the correct quantity and placement.

Denka® plates are not rated like breakers or cables, because they are installed in parallel and not in series with the load. Design rules are based on system capacity and noise characteristics rather than simple ampere ratings. With exception that any over 60Amps breaker must be installed itself even if its SMDB main breaker is covered.

Denka® is designed to operate within its material limits without significant self-heating under normal conditions. Any internal losses are negligible compared to the energy savings from reduced system losses.

Denka® does not attempt to manipulate meters or "trick" them. It works by reducing real losses in the system. Meters continue to measure consumption according to regulations.

Many low-cost "power saver" products provide little or no measurable benefit and are not backed by serious engineering. Denka® is a professionally engineered, industrial-grade solution supported by lab testing, field data, and formal measurement protocols.

No. Denka® is complementary. Good insulation, efficient lighting, proper HVAC design, and responsible operation are still necessary. Denka® helps you extract more efficiency from the electrical side of the system.

The first step is a preliminary assessment: we review your last 12~24 months of electricity bills, tariffs, and a simple description or single-line diagram of your electrical system. Based on that, we can estimate potential benefits and propose a measurement-based pilot if appropriate.
