System overview
Excellent energy saving
The all-inverter heat pump provides highly energy-efficient air conditioning for individual cooling and heating operation all year round.
Great design flexibility for placement in any building
Design flexibility meets the diverse installation needs of high-rise buildings for air conditioners, such as rooftop, concentrated installation of outdoor units and installation on each floor. This can be done by large-capacity combination, sufficient connection capacity, and high static pressure design.
Easy installation and maintenance
The flexible communication method and piping connection make installation and maintenance easy even for large systems.

Energy-saving technologies for boosting operational efficiency
Large powerful propeller fan
The fan using CFD*1 technology achieves both high performance and low-noise operation.
- *1.
- CFD: Computational Fluid Dynamics
3-phase DC fan motor
The use of a DC fan motor with sophisticated driver control improves energy efficiency substantially. In addition, this motor operates quietly.
Subcooling heat exchanger
The double-pipe structure with internal projections achieves great heat-exchanging efficiency.
Sine-wave DC inverter control
The use of a motor with an intelligent power module (IPM) reduces switching loss and achieves great efficiency.
High-efficiency, large-capacity DC inverter compressor
A high-efficiency, large-capacity DC twin-rotary compressor offers excellent intermediate capability.
4-face heat exchanger
The 4-face heat exchanger increases the effective surface area and significantly improves heat-exchanging efficiency.
Front slanted-corner air-intake port
When multiple outdoor units are installed, the uniquely shaped front intake improves the airflow into the heat exchanger.
Elaborate anti-corrosion treatment
PCB and electronic components
High-ambient-temperature-compatible electronic components are used. Silicon coating is applied to all PCB circuits for corrosion protection.
Blue fin heat exchanger
Screws and hinges
Zinc-chrome-acid film treatment applied to all screws and hinges.
Anti-corrosion coated casings
Satisfies the JRA*1 regulation for anti-corrosion treatment (JRA 4002).
- *1.
- JRA: Japan Refrigeration Association
High ambient temperature compatible and corrosion resistant
Applicable to PCB components and refrigeration cycle components
Outstanding cooling capacity
The combination of a large heat exchanger, high-capacity DC inverter compressor, and subcooling equipment provides outstanding cooling capacity.
