Retrofit your fans for more energy savings
Switch from AC to EC fans

Fan retrofits by ebm‑papst

By 2030, the Singapore government aims to reduce energy consumption in buildings and green 80% of all new and existing building stock. To achieve this goal in existing buildings, retrofitting is always the more sustainable option than tearing it down.

Air Conditioning and Mechanical Ventilation (ACMV) systems can account for more than 60% of the energy consumption of a building. Of that value, fans can account for 35% of the energy consumption.

 Therefore, implementing energy-efficient fan technologies can be one of the strategies building owners and facility managers deploy to reduce their energy consumption. 

EC stands for ‘Electronically Commutated’, which means it is a fan with a Permanent Magnet Motor (PMM). EC motors are more efficient than AC motors because they use permanent magnets rather than inducing a secondary magnetic field in the rotor. ebm‑papst has pioneered the development of EC motors and fans, which can be connected directly to an AC mains supply rather than a separate DC power supply, making them easy to retrofit as a replacement for inefficient AC fans.

FanGrid for operational reliability

FanGrids for operational reliability

The modular FanGrid system is flexible and efficient. The fans operate in parallel, which ensures a high level of operational reliability; if one fan fails, the other fans compensate for the missing air quantity.

More on retrofitting

If ventilation and refrigeration systems have been running for several years, it is worth taking a close look at how efficient they are. Upgrades with modern EC fans from ebm‑papst have many advantages, especially when they are well thought through and implemented correctly. But what makes a retrofit a success?

When you handle a retrofit project on ventilation fans, it is important to know what one should definitely do, and what not to do.

Stage one: Site survey
Get in touch with us and we will arrange a free physical survey of your existing equipment to see what you currently use and what you would like to achieve. There is no cost involved in checking the feasibility of the project. Our wide experience of all types of systems means we can quickly give you advice on a possible solution, including potential savings and a payback period.

Stage two: Estimated savings
After our initial feedback, we will consider your needs in more detail and provide an estimate of the potential savings in energy consumption financial cost. We will also indicate the cost of fan installation and the payback period.

Stage three: Trial installation
We have confidence in our estimates but do not expect you to accept them without question. Usually we will recommend an initial trial installation to confirm the figures.

Stage four: Site rollout
Following a successful trial installation, you will have all the information you need to implement a site-wide upgrade.
