For those who have been following my posts, you may realise that I am a raving fan for electronically commutated (EC) plug fans installed in a fanwall configuration.

Why? … because of its simplicity and ease of maintenance. When a fan breaks down, I will only lose 5% capacity in the case of the University of Adelaide, where 20 fans were installed. And the best part is, it will only take at most one hour to replace the fan.

Fan discharge side

Last Thursday, I was sharing this fanwall configuration with a project manager, and he asked: “If this configuration is as good as I said, why isn't there any other such installations?” I really did not know the answer; perhaps people just do not know what they do not know or, may not have been introduced to such configuration.

I was intrigued as well, so why?

I did a quick search on Friday and found … indeed there are many instances of fanwalls. Below are some of the examples.

Managing airflow is so easy, and scaling up the capacity is even easier. No longer the case where I am limited by the capacity of the air handling units or packaged units available in the market, even more so the space constraints. EC plug fans are between 10 to 30% more efficient than AC induction motors, in addition, plug fans do not suffer from the system effect of centrifugal blower fans.
