An EC to EC retrofit not only makes sense from an energy point of view - ebm‑papst achieves energy savings of 10 - 15% when retrofitting EC systems in-house.

A higher level of intelligence

The use of the latest generation of EC fans brings further advantages: Replacement is relatively simple, as the installation sizes are generally identical, and the new EC fans have a higher level of intelligence. Integration into the building management system, the connection of sensors and thus needs-based utilisation or even data-driven added value such as predictive maintenance can be realised.

Electronically Commutated (EC) motors are a significant advancement over AC motors paired with variable frequency drives (VFD). EC motors are not only smaller, lighter, and quieter but also offer superior speed control down to 10%, drastically improving efficiency. With ebm‑papst’s EC motor technology, you can reduce operational costs while making a positive environmental impact.

You can reduce operating costs without replacing your existing system. Legacy systems typically use a single large AC motor with a blower or fan in a large air chamber. Thanks to the compact dimensions of EC motors, they can easily integrate into the existing footprint of legacy systems. Their smaller size also means quieter operation, easier installations, and built-in redundancy, which reduces downtime and simplifies maintenance.
