Large propeller fan

A large propeller fan with an optimized blade angle achieves both high performance and low-noise operation.

DC inverter control

The use of a new active filter module improves efficiency.

DC fan motor

A small, multi-stage DC fan motor contributes to highly efficient, low noise operation.

Large heat exchanger

The use of a large 3-row heat exchanger substantially improves heat-exchanging performance.

Subcooling heat exchanger
