Product Introduction 

The BU module of Gree Super Free Match Series is the latest branch device, which adopts the 

intelligent control technology. Respond to the changes in load of the indoor units, it can coordinate 
the flow rate of the refrigerant well. Otherwise, it is very compact and has a flexible choice about the 
installation location, such as the ceiling of parlor, corridor, balcony,

 

storeroom

 

and etc.
