Features
High ambient operation design
Possible to operate cooling up to 52ºC outdoor temperature

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.
