CITY MULTI’s outdoor unit can operate up to twenty ducted or ductless indoor units, making the system ideal for virtually any type of application — or any variety of applications — within the same building. Do you need air conditioning only on demand in a conference room? Want a central system to cool a large working area all day long? Need precise temperature control in a confined space with no room for ductwork? CITY MULTI works for you what-ever your space and climate control requirements happen to be.
