What Is an Energy Saving Device?

Energy costs are rising. Across industries — manufacturing, shipping, commercial real estate, data centers — electricity bills represent one of the largest and fastest-growing operating expenses. At the same time, businesses face mounting pressure to reduce their carbon footprint and meet sustainability targets. The challenge: how do you cut energy consumption without disrupting operations or making expensive infrastructure upgrades?

That is exactly the problem an energy saving device is designed to solve.

What Is an Energy Saving Device?

An energy saving device (ESD) is a piece of electrical equipment installed in a facility's power distribution system to improve the efficiency of electricity consumption. Unlike traditional energy-reduction measures — such as replacing lighting, upgrading HVAC systems, or retrofitting machinery — an ESD works at the electrical level, optimizing the way power flows through existing equipment without requiring changes to operations.

In simple terms, an ESD reduces the amount of electricity a facility consumes while keeping all equipment running at full capacity. The result is lower electricity bills, a smaller carbon footprint, and reduced strain on power distribution infrastructure — all from a single installation.

Energy saving devices are used in a wide range of settings: factories, office buildings, data centers, hospitals, ships, shopping centers, and residential complexes. They are sized to match the facility's electrical load, with models ranging from small units for single-phase residential circuits to large industrial units capable of handling 1,000 kW or more.

How the FORCE ESD Works

FORCE ESD — Energy Saving Device by ENPOSS is a proprietary device, developed through more than 15 years of R&D and real-world deployment across multiple industries and countries.

The core technology is based on Tourmaline, a naturally occurring mineral known for its ability to generate free electrons. When installed in a facility's electrical system, FORCE ESD uses Tourmaline to improve current conductivity — the electrical current flows more efficiently through the existing wiring and connected equipment, reducing the active power the system needs to draw.

Crucially, FORCE ESD is a no-circuit, no-current device. It does not integrate into the electrical circuit itself. Instead, it connects to each phase of the RSTN (the power distribution lines) within one meter of the main electrical panel, installed by a qualified electrician. Because it is not wired in series with the load, the load circuits are not modified, and there is no ongoing maintenance requirement. Installation itself requires briefly lowering the main breaker, so the electrician and the facility should plan a short outage window.

The device works continuously once installed, with a proven product life of more than 10 years.

Key Benefits of FORCE ESD

ENPOSS describes the following intended effects of FORCE ESD. Actual results depend on site conditions, apply only to the samples and conditions tested, and are not guaranteed for every installation:

• 5–15% reduction in active power consumption

• Lower electricity bills, depending on the tariff structure and load profile

• Possible lower fuel consumption at facilities with combined power systems, depending on the site

• Reduced heat, noise, and vibration in power distribution facilities

• Reduced installation harmonics, which extends the life of connected electrical equipment

Independent test and inspection documents exist for FORCE ESD. Each one covers only the samples and conditions it was written for.

Where Energy Saving Devices Are Used

FORCE ESD is designed for any environment that consumes significant amounts of electrical power. Proven installation environments include:

• Industrial facilities and factories — including manufacturing plants, processing facilities, and heavy equipment operations

• Marine and port operations — vessels, port offices, and port logistics infrastructure

• Commercial and office buildings — shopping centers, office complexes, and mixed-use developments

• Telecommunications infrastructure — mobile carrier facilities and data equipment

• Logistics and cold chain — refrigeration companies, warehouses, and distribution centers

• Media and broadcasting — broadcast companies and media production facilities

• Residential complexes — apartment buildings and multi-unit housing developments

FORCE ESD models are available from 5 kW to 1,000 kW, covering low to high voltage applications up to 6,600V. This range makes the device suitable for small commercial installations as well as large industrial facilities that require significant power saving at scale.
