Detailed description
Inverter compressor technology adjusts power continuously for stable temperatures and minimal energy consumption. The R-32 refrigerant has a low global warming potential and is well suited to modern split systems.
Exceptionally quiet operation
The new-generation low-noise motors used in AUX multi-split indoor units guarantee silent operation and a comfortable atmosphere. Suitable for bedrooms and living rooms where quiet operation is essential.
180° Vector control
The inverter compressor of AUX multi-split systems is controlled via 180° vector control of the sine wave. This advanced digital control method is the latest worldwide development and ensures a longer compressor lifespan and high efficiency in every air conditioner.
Beautiful facade
The growing requirement for cleaner building facades makes multi-split systems a must. AUX multi-split systems save space on terraces and facades while providing the required comfort with one outdoor unit and a wide selection of indoor unit types.
Long pipe runs
Support for long pipe runs gives flexibility when designing large residential or office buildings, allowing the outdoor unit to be placed on the roof or in another location.
Installation
Split system: 1 outdoor unit + up to 5 indoor units (sold separately).
