AIRSTAGE™ VRF Systems J-IIS Series

System overview

Space-saving design

The combination of all-DC technology, a large-capacity DC twin-rotary compressor, and a 3-row heat exchanger has made it possible to design this compact and economical individual air conditioning system.

Flexible system configuration for homes, stores, and small buildings

The compact size and flexible piping design make the J-IIS Series an ideal choice to be installed in tight spaces in residences, stores, and small offices. Multiple indoor units of various capacities and types can be connected.

Small and lightweight outdoor units

The outdoor units in this series are much more compact than conventional outdoor units with comparable capacity. They can be installed on a balcony, completely hidden behind the fence. With a height of less than 1 m, they can be installed in tight spaces such as under the window.

Advanced technologies for high efficiency

Large heat exchanger

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

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.

Smooth airflow grille

The aerodynamically designed grille provides excellent efficiency with little blow loss.

Compact and high-performance DC twin-rotary compressor

High efficiency is achieved across compressor loads. Particularly high efficiency is gained in the low- to medium-load range.

Long piping length

Our advanced refrigerant control technology extends the maximum allowable length of refrigerant piping to 80 m. This provides greater flexibility in system design.

Nonstop operation during oil recovery

The air conditioner maintains uninterrupted cooling or heating operation during oil-recovery mode and keeps the room comfortable.

Easy installation

Confirmation of correct connection
Correct wiring connection and address settings can be confirmed by running a quick check.
  • Displays the number of each connected indoor unit.
  • Displays a duplicate address number assigned to an indoor unit.
