System Outline

Space saving and quiet design

Economical individual comfort is achieved through the DC technology, large capacity DC twin rotary compressor, and 3-row heat exchanger.

Flexible systems for homes, and small-size buildings

Due to its compact size and flexible piping design, J-IIS series can be installed easily in places where installation space is limited such as homes, shops, and small offices. Multiple indoor units of various capacities and types can be connected.


Small and light weight outdoor unit

This model is much more compact than conventional 3 and 4 ton outdoor units. Even when installed on a balcony it fits within the height of the railing. The compact size with a height of less than 3.3ft (1m) allows it to be installed under windows and in tight spaces

Advanced high efficiency technology

Large heat exchanger

Heat exchange performance is substantially improved by mounting of 3-row to the heat exchanger.

DC inverter control

Efficiency is improved by mounting of new active filter module.

DC fan motor

Miniaturized, low noise, high efficiency, multi-stage DC fan motor is mounted.

Large Propeller Fan

High performance and low noise realized by large propeller and optimization of angle.

Smooth airflow grille

This grille was aerodynamically designed for good efficiency with little blow loss.

High Efficiency DC Twin Rotary Compressor

DC twin rotary compressor provides great performance under all load conditions. Its performance is optimized for part-load operation.

Long piping length

Our advanced refrigerant control technology allows us to achieve a total refrigerant piping length of 262ft. (80m). This opens up new possibilities in system design.

Non-stop oil recovery operation

A comfortable room condition is maintained during oil recovery mode because the product continues to operate without stopping the cooling or heating operation.
