Smart and cutting edge design
Extensive lineup from 8HP to 48HP in 2HP increment
Connectable indoor unit capacity ratio up to 150%
Handles changes in the temperature difference
Simultaneous cooling and heating operation
using 1 refrigerant system
Cooling and heating can be freely selected for each
indoor unit to provide simultaneous cooling and heating
in rooms with large temperature differences.
Annual cooling operation
Energy saving of the operating
systems has been approved
as heating and cooling modes
can be operated at the same
time on the same air
conditioning piping system.
Our Heat recovery systems achieve high operating energy efficiency
by drawing heat from the room to be cooled and transferring it as
energy for rooms that are to be heated.

The operation mode can be freely changed when there
are large temperature differences during the day, such
as between seasons.
Use annual cooling operation for the rooms and other
spaces that require constant temperature control
throughout the year.

Features
4-face heat exchanger
Heat exchange efficiency is significantly improved by
the introduction of a new 4-face heat exchanger that
increases effective surface area.
Front intake port
(corner cut air inhaling structure)
In multiple outdoor unit installations, the unique front
intake design improves airflow into the Heat Exchanger.
Energy saving technology that boosted operation efficiency
3 phase DC fan motor
Efficiency is substantially improved by high efficient
motor with sophisticated driver control. In addition,
low noise is realized by DC fan motor.
Sine-wave DC inverter control
High efficiency is realized by adoption of reduced
switching loss IPM.
Subcool heat exchanger
High Heat Exchange efficiency is achieved by using
an internal projection shape double pipe
construction.
High efficient compressor
Large capacity DC inverter
