Electrostatic precipitators (ESP)

Electrostatic precipitators (ESP)

Efficient and reliable ESP solutions for dust emission control

Engineered to deliver efficient dust emission control down to 5mg/Nm3, our ESP solutions are not just successful and reliable, they are also affordable, offering the lowest total cost of ownership (TCO) and operating expenses (OPEX). With more than 3,000 ESPs installed in a wide range of industries and challenging processes, we offer bespoke solutions for every application.

what we offer

Trouble-free dust emission control

All industries are facing more strict and tough emissions limits, which bring along extra cost and process pressures. Failure to comply is not an option – but the cost of compliance can be prohibitive. It doesn’t have to be this way. Our ESP solutions beats competition (including fabric filters) in efficiency, reliability, TCO, OPEX and with emissions below 5mg/Nm3. With more than 3,000 ESPs installed in a wide range of industries, FLSmidth provides ESP solutions for processes within cement, pulp and paper, iron and steel, and metallurgical production. We have the proven experience and the know-how to understand your process requirements or challenges. This means we can design and configure the most optimal and efficient ESP, while complying to the most stringent dust emissions regulations. As part of our unwavering commitment to environmental responsibility, we are continually developing our ESP technology to ensure that our customers consistently operate well below the prescribed emission limits. This is achieved through optimized gas distribution, improved particulate capture, and sustainable practices, including reduced energy consumption.

Key Benefits

Low-emissions, low-energy, a more sustainable electrostatic precipitator


Reduce dust emissions

The continued development of our ESP technology has enabled us to reduce dust emissions to well below 5mg/Nm3, achieved through optimal gas distribution and greater particulate capture.

Compact footprint

We have optimised gas and dust distribution in the ESP, enabling 100% utilisation of the installed collection area. This, combined with our extensive process know-how and specific product design for each application has enabled us to minimise the equipment footprint.

Reliable dust emissions control

The latest advances to the PIACS DC4 ESP controller enable you to achieve lower energy consumption, enhanced ESP performance and greater emissions capture than ever before.

Simplify maintenance requirements

The high quality and flexible design ensure minimal wear and tear and require only minimal maintenance. Wear parts are placed outside the dust-stream, allowing trouble-free operation and easy access to the parts.

Upgrade existing ESPs, regardless of OEM

We have the expertise and resources to enhance the performance of any ESP, regardless of original make. Whether you want to replace, rebuild, or upgrade, we can make sure you are able to meet your production and emission goals in a cost-effective manner.
Product Features
Enhance performance with ESP upgrades
ESP parts replacement and upgrades
In addition to new ESP systems, we offer a variety of improvement and upgrade options for your existing Air Pollution Control equipment. Whether your system has been in operation for 30 years or 3, we support and supply parts for all types and makes and models, regardless of OEM. Our experienced service organisation can help you improve performance by providing: Maintenance assistance and advice Troubleshooting Upgrades Spare and wear parts We’re always focused on achieving low total cost of ownership and a long equipment life, alongside sustainable emissions reduction. Choose your ideal option Rebuild : refurbish equipment to original condition and capacity. Upgrade: improve performance and reliability by installing the most modern components. Replace: build a new unit alongside your existing APC equipment. This enables you to minimize downtime, as it requires only a very limited shut down to reroute ducting.
Make an informed decision
Considering the numerous possibilities, determining viable solutions and selecting the best option to maximise performance can be very challenging. Each option may require a different investment amount, implementation challenge and shutdown schedule, with very different potential results. Together, we will explore the advantages and disadvantages of each potential solution, allowing you to make an informed decision.
