EC technology developed by ebm-papst offers a huge potential for energy savings in electrically powered fans, achieving an efficiency of over 90% when compared to conventional fans with asynchronous motors.
This higher efficiency translates into lower energy consumption by up to 50% compared to AC solutions. EC technology motors also enable the speed of fans to be controlled so that the air volume can be adapted to suit specific requirements, resulting in additional energy savings.
Update on MEPS and HEPS
The recently released ‘In From the Cold 2010-2020 strategy’ has identified considerable potential to reduce energy consumption and lifecycle costs by increasing the uptake of more efficient fan motors in all new equipment and as replacements in existing equipment.
It further identifies a strong role for MEPS in raising the efficiency level of the lowest performing units.
In From the Cold advocates:
Adoption of efficiency performance policy measures for all single-phase and three-phase electric motors supplied into the ANZ market that drive air moving fan blades or impellers either incorporated or intended for incorporation into non-domestic refrigeration equipment, including combined fan and motor assemblies.
Investigation of the following products for MEPS and HEPS:
- Electric motors for driving fan blades or impellers that are supplied as separate components with output rates ≥ 5 Watts and above
- Combined fan/impeller motor assemblies supplied as complete units with input ratings of ≥ 15 Watts
EC technology fan motors by ebm-papst will be able to meet future requirements. ebm-papst already offers an energy-efficient alternative in GreenTech EC technology that not only meets but exceeds the energy efficiency requirements.
Successfully combining motor, electronics and aerodynamics, ebm-papst's EC technology fans go beyond energy efficiency by operating silently thanks to their optimised commutation techniques and the aerodynamic configuration of the impellers.
The reliability and durability of these fans prove that EC technology motors are the better alternative when planning energy-efficient devices and installations to meet upcoming energy-efficiency requirements.
