Fan Energy Upgrades
Replacing AC fans with EC fans allows optimisation of cooling systems for ultimate energy efficiency, potentially reducing energy usage by up to 70%.
Fan Energy Upgrades
The energy consumption of HVAC equipment can often account for more than 40% of a commercial building’s energy consumption. Simple maintenance improvements to the efficiency of installed systems can offer considerable energy and CO2 savings to the application.
Replacing AC fans with EC fans allows optimisation of cooling systems for ultimate energy efficiency, potentially reducing energy usage by up to 70%. AC fans (up to 12KW) can normally be upgraded and, in most cases, EC fans and drives are directly interchangeable with the AC predecessors. Any voltage combination can be accommodated i.e. DC or AC single or three phase, as the electronics are fully integrated into the motor. EC fans can be supplied in different configurations including backward curved centrifugal fans which are mainly found in AHUs and IT cooling units and axial fans which are normally fitted to chillers and condensers.

EC fan upgrades – the benefits
EC fans offer enhanced control and provide the most simple, but effective solution for reducing energy consumption, essentially providing the same output for less input on just a 10% reduction in air flow can save up to 33% in energy consumption.
Setting new standards with regards to reliability, service life and energy consumption. EC fans are fully compatible with most units, meaning that straight-forward, cost-effective EC fan upgrades can be carried out with minimal disruption.
Benefits of EC fans:
- Up to 70% potential energy saving
- Continuous, integrated variable speed control matched to load requirement
- Direct drive motors for maintenance free operation
- 50% more efficient than previous generation fans
- Reduction in noise levels
AC fan / EC fan comparison
With an EC fan, less power input is required to achieve the same fan speed as the AC fan, hence the power saving potential
