EC fan upgrade for air-handling unit - ebm-papst

The video shows the retrofit of a ventilation system using ebm-papst EC fans. It shows that it is perfectly possible to optimise the energy use of a ventilation system without replacing the ventilation unit.
One way is to look at the fan, the most energy-consuming component in a ventilation system. If the system ism ore than 10 years old, then it is most likely equipped by a belt-driven fan. This can be replaced by a centrifugal fan, which has a combined and optimised impeller and EC motor, making it a highly energy-efficient solution. This also makes frequency converter, shielded cables and motor protection unnecessary. Before replacing and AC fan with an EC fan the airflow and pressure of the existing fan needs to be determined, in order to match the airflow performance of the new fan with the existing one.
The video continues to show the rollout of the retrofit. Replacing an old, belt-driven AC fan with an ebm-papst EC plug fan typically results in a 30-70% energy saving. The power usage in the case shown was more than halved, from 510W usage of the AC fan (already frequency regulated) to 214W usage of the EC fan. This means that the investment is typically recovered in 2 to 2.5 years.

Hi, I'm interested to do replacement to my home unit. just need to know what is the noise level for the replacement fan in dbm?

[@SimonBradwell]

Hello. To help with your two questions: 1) The CFM will depend on the site. When we install a fan we ensure that the benchmark airflow is matched or improved such that the air handling unit is working as it was or better. 2) Our EC fans have built in speed control options that can be accessed by a BMS. No other external VFD should be used. Thank you for your inquiry. Simon

Hello.Is it DC motor and the speed control is change the motor voltage ? thanks

[@SimonBradwell]

@@BeWater22 Hi, in order to change the speed 2 methods are suggested. 1. ModBus - this gives full two way control to a defined speed. 2. 0-10V or 0-20mA input. These driving signals will drive the fan speed up and down but not to a defined speed. Do not change the supply voltage. I trust this helps. Simon

Uhh... that belt-driven fan was a "gerbil-cage fan," right? Then it already _is_ centrifugal.

[@manjunathc1538]

need to understand on the CFM level (air flow) post installation of EC fans, can we get same CFM like earlier? alos let us know EC fans are driven through VFD

I need a 40000cfm air EC blower - 02 nos

[@mohdfarhan5708]

can this item change my carrier wcpu 50pv360 model blower fan unit.

[@vikramjitsinghsawhney7721]

Is it true??

[@SimonBradwell]

Yes. Thank you for your question.

[@muhammadgullabbas9176]

any distributor in Pakistan ?

the video image is too poor, you need to fix it more

[@SimonBradwell]

Thank you for your feedback Quang. What improvements should we make? What information do you need? Thank you

Hello Tinh, unfortunately we do not have the original footage and can't UPGRADE (!). If you have any questions, please ask.
