Enhanced inverter performance and system performance are achieved by the addition of a ?Direct Current? drive, resulting in up to 10% more efficient than standard 'AC' Alernating Current) Systems.

The variable speed compressor(inverter) enables the system to rapidly reach the desired roomtemperature setting. Once the desired room temperature has been achieved the compressor rotationspeed is reduced, saving up to 30% in energy usage (when compared to standard fixed speed systems)

This unit is ducted, meaning airflow can be ducted to several areas in the room or another small area, ideal for bedrooms with  an on suite bathroom. The unit has its own internal drain pump to remove accumulated condensation water from the drain pan even while it is operating. A float switch monitors the water level and automatically activates the pump as necessary.

Up to 4meters of ductwork may be installed as the unit comes with a ?highpressure? setting, enabling units to overcome the added external pressure.
