High static pressure duct
For long ducts and large spaces, up to 22 kW. Quiet, with automatic airflow adjustment.
Ducted
KHTAP · KHTB · KHTA
Fujitsu's high static pressure ducts are for long duct runs and large spaces. There are three series: KHTAP (compact, up to 200 Pa), KHTB (up to 250 Pa) and KHTA (high efficiency, up to 260 Pa).
Sizes from 3.5 to 22 kW. The unit sets the airflow the installation needs by itself. KHTAP 9.5 to 13.4 kW and KHTB also come three-phase 400 V; KHTA 15 to 22 kW are three-phase.

Features
Efficient and quiet
A V-shaped heat exchanger, an air stabiliser and a high-efficiency DC fan motor keep the unit efficient and quiet.
Small, light outdoor unit
The outdoor unit is more compact and lighter, so it fits tight spaces.
Automatic airflow adjustment
The unit works out the airflow the installation needs and sets it by itself.
KHTA: splits in two
The indoor unit separates into a fan section and a heat exchanger section to pass through a ventilation opening, and it has a carrying handle.
Central control (option)
With optional MODBUS or KNX interfaces, the air conditioning is controlled together with the building's other systems.
