Hello,
I have an evaporative cooler which is too noisy for the application I want to use it for, I'd like to ask if it's possible to use a dimmer for it in order to drastically reduce the noise. Of course I'm aware that decreasing the fan speed will decrease the efficiency of the device, but this is not a problem at all, it's already oversized. My issue is only the noise (around 60dB at minimum...).
In particular I'm talking of this device:
I know there is also a water pump inside, but I can simply disconnect it and run it separately.
Do you think it's a feasible workaround?
Will decreasing the speed to 1/2 or 1/3 of the selectable lowest speed significantly decrease the noise?
Which type of dimmer do I need? one for induction motors, right?
Thanks
