Retrofit Your ACMV System
Air Conditioning and Mechanical Ventilation (ACMV) systems can account for more than 50% of the energy consumption of a building. Of that 50%, 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. Read more here.
Energy-Efficient EC Technology
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.

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. Watch the video to learn more.
Applications & Case Studies
Air Handling Units: An air handling unit (AHU) is a piece of equipment that circulates the air as part of a heating, ventilation and air-conditioning system. It is usually a large metal box that contains filters, cooling coils and fans. Depending on the needs of the building, the size of the AHU will vary.

CRAC Unit: A Computer Room Air-Conditioning (CRAC) Unit provides precise and constant temperature level in data centres. To prevent malfunctioning of critical infrastructure, it is absolutely critical that fans in CRAC units are reliable.

Cooling Towers: A cooling tower is a heat rejection device, which extracts waste heat to the atmosphere though the cooling of a water stream to a lower temperature.

Condensers: In air-cooled condensers, the heat from the gaseous refrigerant is transferred to the ambient air. Axial fans are usually used to direct air at the fins of the heat exchanger in the condenser, dissipating the heat. In this process, the refrigerant is cooled down to such an extent in the condenser that it condenses.

Retrofit - the right way!
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? Read the article here.
The Dos & Don’ts for Ventilation Fan Retrofit
Retrofit Stages: From Site Survey to Site Rollout
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.
