Cassette units MULTI - AUX air conditioning systems

Cassette units

The quiet and efficient AUX cassette units are ideal for commercial spaces with suspended ceilings—such as offices, conference rooms, restaurants, and retail stores. Thanks to 360° perimeter airflow technology and rapid cooling/heating functions, they can provide comfortable conditions in every corner of the air-conditioned room.

EFFICIENT AND COMFORTABLE COOLING

Maximum comfort indoors

The quiet and efficient AUX cassette units perform exceptionally well in commercial spaces with suspended ceilings—such as offices, conference rooms, restaurants, and retail stores. The specially designed decorative panel of the AUX cassette air conditioner enables uniform cooling of every corner of the room, ensuring maximum comfort and a pleasant indoor environment.

360° PERIMETER AIR FLOW

Effective air distribution

Additional outlet vents located at the corners of the panel allow air to be directed in all directions, eliminating the possibility of uneven temperature zones and drafts. The advanced perimeter airflow technology provides 360° distribution of cooled air, ensuring effective and consistent air conditioning even in large and challenging spaces.

HIGH QUALITY INVERTER COMPRESSOR

Guarantee of energy efficiency and reliability

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.

Anti-corrosion casing

Longer lifespan and better aesthetics

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.

OPTIMISED PIPING DESIGN

Improving cooling capacity

The design provides additional cooling and increases the cooling capacity by separating the refrigerant inlet and outlet, which optimizes the refrigerant flow and enhances overall system efficiency. This separation also helps maintain stable operating temperatures, contributing to improved performance and reliability.

180 sine wave control

Smooth and efficient operation of the compressor

The DC inverter compressor uses 180° sine wave control. The solution makes the compressor motor run smoothly and the efficiency increases significantly.

OUTDOOR UNIT DRIP TRAY HEATER

Efficient operation in heating 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.

AUTOMATIC RESTART

Setting memory in the event of a power failure

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

INTELLIGENT DEFROSTING

Effective operation at low ambient temperatures

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.

WIDE OPERATING RANGE

Reliable operation even in adverse weather conditions

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.

IN-BUILT DRAIN PUMP

Lifting height up to 120 cm

As standard, the cassette unit is equipped with a condensate pump which allows to drain water condensate up to 120 cm above the level of the condensate tray.

Fresh air intake

Comfort and safety

The cassette unit casing is equipped with specially prepared opening for fresh air inlet. The device is thus able to supply the room with fresh air. Fresh air intake increases the air quality inside the building, providing health and comfort to people staying in the room. Optimised electrical box offers easy service access and high fire resistance.

R32 REFRIGERANT

Ecological, highly effective, safe

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.

HIGH ENERGY EFFICIENCY

Guarantee of energy-saving operation

Owing to the use of a highly efficient DC inverter compressor, adjustable fan motor and advanced 180° sine wave vector control technology, multi 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.
