Efficient and discreet units, giving the greatest freedom in designing the system.
Efficient and hidden units, giving the greatest freedom in designing the system. Thanks to the extremely flat design, the casing will fit even in low ceiling spaces. Adjustable static pressure up to 160Pa allows the using long ventilation ducts and the automatic ESP adjustment function guarantees comfortable cooling and heating at all times, regardless of the length of the ducts.
The AUX duct unit can be additionally equipped with a condensate pump, which allows to drain the water condensate up to 70 cm above the drain pan level.
Adjustable discharge pressure from 0 to 160Pa allows greater flexibility in the design of the installation – making it possible to distribute ventilation ducts over long distances.
The design of the duct unit allows two ways of mounting the air inlet, giving greater freedom in designing the system. As standard, the air inlet is located at the back of the unit. If the room arrangement requires it, the air can also be taken in via the lower air inlet (optional).
The Automatic Static Pressure Control (ESP) function provides comfortable room conditions with low noise levels. The fan speed and the amount of supplied air are automatically adjusted to the length of the ventilation duct, so as to provide a constant air flow regardless of the length of the pipework.

The inverter rotary compressor of AUX air conditioners guarantees reliable and efficient operation of the devices as well as the highest energy efficiency parameters. It also provides low operating costs and a low level of noise. Durable and high-quality materials of the compressor guarantee its long and failure-free operation.
All AUX air conditioning units operate using the newest ecological refrigerant R32, which, comparing to the commonly used R410A refrigerant, is characterised by higher efficiency and a lower greenhouse effect. It also does not damage the ozone layer.
Owing to the use of a highly efficient DC inverter compressor, adjustable fan motor and advanced 180° sine wave vector control technology, commercial AUX systems achieve high energy efficiency parameters, providing reliable, efficient operation with low energy consumption. All multi air conditioners are class A ++ in cooling and A+ in heating mode.
AUX multi air conditioning systems are characterised by reliable, stable operation even in extreme ambient temperatures. Owing to the use of modern technologies and high-quality components, AUX devices operate in a wide range of outdoor temperatures, i.e. from -15°C to 52°C in cooling mode and from -22°C to 24°C in heating mode, providing a high level of comfort in the room in all the seasons of the year.
The casing of the outdoor unit has been covered with a number of protective layers, protecting it against insects, rodents, moisture, dust and fire. It guarantees a long lifespan of the device and an better aesthetics after many years of exposure to adverse weather conditions.
The air conditioner activates the defrosting mode only when necessary and only for the time needed to defrost the heat exchanger, which allows the unit to operate almost continuously in heating mode. The intelligent defrosting system used in AUX air conditioners improves the energy efficiency of the devices by 5% and increases the heating efficiency as much as 20% at low ambient temperatures.
In the event of a power failure, the device records the last settings and restarts after resuming the power supply, automatically restoring the previously set operating mode
Outdoor units of AUX commercial air conditioner series are equipped with a drip tray heaters, which allow the devices to operate efficiently in heating mode even in severe frosts, preventing the heat exchanger from icing.
The DC inverter compressor uses 180° sine wave control. The solution makes the compressor motor run smoothly and the efficiency increases significantly.
