Fixed-speed asynchronous motors are still often implemented to drive fans in the refrigeration, air conditioning and building services sector. But these have one major drawback: relatively poor efficiency. This has negatively effects energy consumption in virtually all applications.
Fixed-speed asynchronous motors are still often implemented to drive fans in the refrigeration, air conditioning and building services sector. But these have one major drawback: relatively poor efficiency. This has negatively effects energy consumption in virtually all applications.
There is a way to save energy: ebm-papst can replace fans that use AC motors and are usually inefficient with highly efficient EC technology in the same mechanical design. Switching from AC to EC fans not only benefits the environment and cuts operating costs, it also enhances comfort.
EC Upgrades Services
Service that helps you save money
We at ebm-papst consider site inspection a part of EC Upgrades package. This can help in assisting you with the upgrade process and design or simply ensure that an existing installation is as per our installation guidelines so there are no nasty surprises later resulting from faulty installations.
We are also here to assist after the upgrade should any issues arise.
We can plan your M&V requirements and installation. This usually goes hand in hand with energy audits, exploring and accessing grants for building upgrades as well as processing the paperwork to create white paper certificates such as ESC’s under the ESC scheme in NSW or VEEC’s under the Victorian Energy Upgrades scheme in VIC.
We can install the fan upgrade for you. Installation includes but not limited to removal of old fan supply of EC fans, installation of EC fan assemblies. Basic electrical work, installation of sub-board outside the AHU with Auto/Manual/Off switch and circuit breaker, installation of potentiometer for speed control in manual mode, installation of Isolator switch. Connection of existing 0..10V from BMS signal. Basic commissioning in case of a fix speed (DOL) fan. We also work after office hours.
We conduct level 1 and level 2 energy audits for various organisations, assisting them in identifying and evaluating energy saving opportunities, based on key criteria such as implementation costs, energy reductions, and Return-on-Investment (ROI). This allows the organisations to better understand their energy usage and cost, to prioritize their saving opportunities.
EC motors are extremely efficient, unbeatably compact and operate very smoothly. Their efficiency levels are always superior to common asynchronous motors. The energy-saving motor’s efficiency levels already far surpasses efficiency class IE4. And it is considerably quieter than conventional belt-driven AC fans.
The EC motor is equipped with control electronics, permitting precise adjustment of the air volume to suit requirements. It is also offers advantages in terms of EMC issues, and the unit only has to be connected to one supply point. EC motors have established themselves as fan drives in many fields. The term “EC motor” is often used for different concepts, but one thing is always the same: The way that GreenTech EC motors from ebm-papst are designed makes critical rare-earth magnets unnecessary.
