Question Two speed fan

I have a question..
The majority of machines I have hacked to convert to heat pumps have had single speed condenser fans. I have just 'inherited' two Fuji 7kW machines that have 2 speed fans.

My question is why two speed? What is the advantage of running the fan at a lower speed? Just energy saving?
