Ducted units

KAISAI ducted units (KTB)
Due to their high efficiency and low noise level, KAISAI ducted air conditioning units are suitable for large surface facilities such as hotels, restaurants, cinemas and conference rooms. A major asset of the ducted air conditioning systems is the possibility to provide free distribution of air with ducts and vents across the entire space of a suspended ceiling.
