Outdoor unit


Designed as a new, energy efficient R410A single or twin split system, the Super Digital Inverter 4 is also the perfect replacement for existing R22 and R407C systems. Able to replace both indoor and outdoor units whilst utilising the existing pipework*, the result is a quicker, cheaper, more environmentally responsible installation.



The new Super Digital Inverter, series 4, sets new standards for industry energy performance.

The units are equipped with the new Eco-driving twin-rotary compressors, where the magnetic action minimises the rotor friction loss.

The compressors can work at very low speed, down to 10 r/s, providing excellent energy performances in both cooling and heating.

The seasonal and the rated efficiencies are the highest in the industry for capacities from 10 to 12.5 kW.

The air management system has also been improved: high efficiency fan motors, larger fans and new fan grille design all contribute to the exceptional energy performance.

Piping and operating limits have also been improved. The new system can work at extremely low temperatures, in cooling and heating. The extended pipe length is now up to 75m.

SDI4 is designed for R410A refrigerant, and R22 or R407C replacement systems that consume more energy.


Key Features

Highest EER/COP values in the industry.

All systems are A-class rated in cooling and heating operation. Thanks to its new Eco-driving compressors, the new systems provide excellent seasonal energy performance, thus saving up to 70% annual energy cost compared to fixed speed systems.

Eco-driving twin-rotary compressors: The structure and magnetic action of the new Eco-driving twin-rotary compressors provide excellent energy performance at full load as well as in partial load conditions.

Longer pipe runs, up to 75m length and 30m elevation for increased installation flexibility.

Wide operating range: down to -15°C in cooling mode and down to -20°C in heating mode.

High static fan operation is possible utilising a dip switch in the outdoor unit enabling the units to be installed in a plant room.

*Provided the exisiting pipework meets current legislation regarding the pressure rating of  R410A
