Walk through any plant and you will see equipment that wastes power: motors running throttled, fans at full speed and lights left on. Energy saving products for industries address that waste, but they differ widely in what they fix.
To see the full range we work with, browse our energy saving products and solutions.
This guide compares eight options, shows where each one pays off, and explains how to choose the first one with data instead of brochures.
The Short Version
• Motor-driven loads dominate industrial electricity, so start there.
• Controls and right-sizing usually beat replacing equipment outright.
• Every product works only on certain loads, so match product to load.
• Measure before and after, or you cannot prove savings.
Why Do Motors And Cooling Dominate Industrial Energy Bills?
Electric motor systems use 72% of industrial electricity worldwide, so pumps, fans, compressors and conveyors decide most of your bill. Most energy saving products for industries therefore target motor-driven loads.
That figure comes from the IEA 4E Electric Motor Systems Platform policy brief, which also notes that audits, incentives and monitoring programmes can unlock significant savings in existing motor systems.
A UNIDO-commissioned study from Lawrence Berkeley National Laboratory estimated the cost-effective saving potential at 27% to 49% for pumping systems and 21% to 47% for compressed air, across the countries it covered.
Your plant will differ, which is why the first step is always measurement.
What Are The Best Energy Saving Products For Industries?
The best energy saving products for industries fall into eight groups: voltage optimisation, variable speed drives, efficient motors, EC fans, lighting, power quality equipment, compressed air controls and monitoring. Each fits different loads.
| Product | What it does | Best for | Watch out for |
|---|---|---|---|
| Energy saver (voltage optimisation) | Trims excess supply voltage and current | Lighting, lightly loaded motors, mixed loads | No saving on LED, drives or IT loads |
| Variable speed drives | Match motor speed to demand | Pumps, fans and compressors with varying load | Harmonics and wrong sizing |
| High-efficiency motors | Cut motor losses | Long-running, heavily loaded motors | Replacing a motor that rarely runs |
| EC fan retrofits | Replace old fans with speed-controlled fans | AHUs and cooling towers | Verify airflow after retrofit |
| LED lighting and controls | Cut lighting power and switch hours | Warehouses, shop floors, car parks | Poor design and glare |
| Power factor and harmonic equipment | Cut reactive power and distortion | Plants with penalties or drive-heavy loads | Resonance with existing capacitors |
| Compressed air controls | Cut leaks and pressure waste | Plants with large compressors | Leaks return without checks |
| Monitoring systems | Show where energy goes, live | Every plant | Data without owners saves nothing |
Many plants combine three or four of these over several years. The order matters more than the count, because early savings fund later projects and early data shows which projects deserve the money.
How Do Voltage Optimisation And Energy Savers Work?
An energy saver lowers excess supply voltage toward what equipment needs, so voltage-dependent loads draw less power. It suits lighting and lightly loaded motors, but not LED, drive or IT loads.
The ES25 energy saver is ES Electronics’ product for industrial and commercial buildings. The company quotes savings of up to 25% on suitable motor and distribution board loads, and payback that can be as short as one year.
Treat those numbers as a ceiling for the right load mix. Log your supply voltage and list your loads by type first, then verify the saving with sub-meters after installation.
When Does An Energy Saver For Motors Beat A New Motor?
An energy saver for motors works best on oversized or lightly loaded motors that stay in service, while a high-efficiency replacement suits motors that run long hours near full load. Check real loading before choosing either.
Variable speed drives deliver the largest savings on pumps and fans, because power falls roughly with the cube of speed. In an ideal case, cutting speed by 20% cuts power by about half. Real systems save less because of losses and static head, but the direction holds.
Right-sizing matters too. A motor running far below its rating wastes energy through poor efficiency and power factor, so replace or resize it before adding any other device.
Where Do EC Fans And Cooling Upgrades Fit?
Among energy saving products for industries, EC fans suit air handling units and cooling towers that run for long hours at varying load. They replace old fans with efficient units whose speed follows demand, cutting both power use and wear.
ES Electronics’ EC fan retrofits for air handling units and cooling towers can cut HVAC energy by up to 50%, depending on load, hours and the equipment you start with.
Pair retrofits with sensible controls. Set points, dampers and coil valves must let the fans slow down, otherwise the new fans run flat out.
Which Power Quality And Lighting Products Matter?
Power factor correction and harmonic filters matter in plants with penalties or many drives, while LED lighting with controls matters wherever lights burn for long hours. Both reduce waste, but through different routes.
• Power factor correction: automatic capacitor panels cut reactive power, which lowers losses and avoids tariff penalties.
• Harmonic filters: active filters cancel distortion from drives and UPS units that overheats cables and transformers.
• LED lighting: cuts lighting power substantially, and controls such as timers and occupancy sensors cut hours.
Check for harmonics before adding capacitor banks, because capacitors can resonate with the network and fail early. A short power quality log across a normal week usually settles the question.
How Does Monitoring Keep The Savings Real?
Monitoring shows where energy goes and confirms that each product delivers what it promised. Live data also flags drift early, so a stuck damper or an overridden set point is fixed within hours.
IoT-based energy monitoring gives dashboards, smart alerts and remote control. Research on US federal buildings found that meters alone save very little, so pair the data with a monthly review and a named owner.
A short monthly meeting is enough. Review consumption by load, check alerts that were ignored, and decide on one action for the next month. Teams that keep this habit hold their savings for years, while those that skip it see consumption creep back.
How Do You Pick The First Product?
Choosing among energy saving products for industries starts with a measured baseline. Rank loads by consumption and running hours, then pilot the product with the best fit, so you never buy for a load that cannot respond.
Resist the urge to buy several products at once. A single pilot on one feeder, one air handling unit or one compressor teaches your team how to measure, review and scale, and it keeps early mistakes small and cheap.
1. Audit: an energy audit measures loads, voltage, power factor and harmonics together.
2. Rank: list opportunities by saving, cost and payback.
3. Pilot: install on one line, one AHU or one feeder first.
4. Verify: compare before and after on the same loads.
5. Scale: roll out where the pilot proves the case.
What Claims Should You Question?
Question any claim of one fixed saving for every plant, any claim without a named load type, and any offer without a measurement plan. Sellers of energy saving products for industries should explain where their product works.
A credible energy efficiency product comes with a clear explanation of where it works and where it does not. Watch for these warning signs:
• A promise of 30% or more with no site data
• No list of the load types the product suits
• No baseline or verification method
• No site references you can call
• Pressure to skip an audit
Good energy conservation products also come with local service, spares and engineers who answer questions after the sale.
Frequently Asked Questions
What are the best energy saving products for industries?
The best choice depends on your load mix. Motor-driven loads such as pumps, fans and compressors usually offer the largest savings, so drives, EC fans and efficient motors often lead.
Which product pays back fastest?
Controls, leak repair and voltage optimisation on suitable loads usually pay back fastest. Replacing motors or chillers takes longer, so rank options by measured payback.
Do energy savers work on LED lighting?
No. LED drivers draw similar power at any supply voltage, so savings come from older discharge and inductive-ballast lighting and from suitable motors.
Do I need an audit before buying?
Yes, ideally. An audit shows which loads respond to which product, and gives you a baseline to prove the savings later.
Can small plants benefit?
Yes. Smaller plants gain from the same energy saving products for industries because they also run motors, lighting and cooling, so start with the largest loads.
What data should I share with a supplier?
Share 12 months of electricity bills, a load list, running hours, single-line diagram and any voltage or power quality logs. Better data produces better recommendations.
