❄️🔥 18,000 BTU Heating & Cooling

With an 18,000 BTU capacity, the Hisense AUC-18HR4SAA1 is designed to provide powerful climate control for appropriately sized indoor spaces.

Unlike a cooling-only air conditioner, this model provides both cooling and heating, making it suitable for year-round temperature control.

The temperature operating range shown in the supplied manual is:

• Cooling: 16–30°C
• Heating: 16–30°C

The actual cooling performance required for a room depends on factors such as room size, ceiling height, insulation, windows, occupancy and heat generated by equipment.

⚙️ DC Inverter Technology

The Hisense AUC-18HR4SAA1 uses DC inverter technology to regulate compressor operation according to the cooling or heating demand.

Instead of continuously operating at one fixed output, inverter technology allows the system to adjust its operation as indoor conditions change.

Benefits include:

• More consistent temperature control
• Efficient long-duration operation
• Reduced temperature fluctuations
• Comfortable heating and cooling
• Quieter operation compared with constant full-power cycling

The model is also listed with an A++ energy-efficiency rating in current Kenyan product information.

🌬️ 4-Way Airflow

The ceiling cassette design distributes conditioned air through four directions, helping spread cool or warm air throughout the room.

This makes the AUC-18HR4SAA1 particularly suitable for open commercial environments where broad air distribution is important.

4-way airflow provides:

• Wide air distribution
• Improved room circulation
• More consistent temperature
• Reduced hot spots
• Better comfort across larger open areas

• Commercial buildings

Smart control can make it easier to manage the AC without relying exclusively on the physical remote control.

🏨 Room Card Control

The AUC-18HR4SAA1 also features Room Card Control, making it particularly suitable for hospitality applications such as hotels and serviced apartments.

Room-card integration can allow the air conditioner to be linked to room occupancy management, helping businesses manage AC operation when rooms are occupied or unoccupied.

💧 Humidity Sensor

The system includes a humidity sensor, allowing the air conditioner to monitor humidity conditions as part of its climate-control operation.

This is particularly useful in environments where maintaining a comfortable indoor atmosphere is important.

🏢 High Ceiling Mode

This is useful for spaces such as:

• Showrooms
• Restaurants
• Retail stores
• Churches
• Conference halls
• Offices
• Commercial premises

🌿 Fresh Air Intake

The supplied manual also indicates Fresh Air Intake functionality.

This feature can support air circulation and ventilation strategies where fresh-air integration is part of the building’s HVAC setup.

Actual fresh-air installation requirements should be handled by a qualified HVAC technician.

🧼 Silver Ion & High-Efficiency Filtration

The unit incorporates filtration designed to help maintain cleaner circulating air.

Features indicated for this model include:

• Silver Ion Filter

The washable filter also makes routine maintenance easier, as it can be cleaned periodically to help maintain proper airflow.

For best performance, filters should be inspected and cleaned according to the manufacturer’s maintenance recommendations.

🚀 Powerful Airflow

According to the manual supplied with the unit, airflow is approximately:

• High: 980 m³/h
• Medium: 840 m³/h
• Low: 720 m³/h

Multiple fan-speed settings allow airflow to be adjusted according to the room’s requirements and desired comfort level.

🤫 Comfortable Low-Noise Operation

The cassette design places the indoor unit neatly into the ceiling, helping maintain a clean interior appearance while keeping the air-conditioning system unobtrusive.

The system is designed for comfortable operation in environments where excessive noise can be distracting, including offices, hotels, restaurants and meeting rooms.

These features are particularly useful in offices, hotels, restaurants and commercial premises.

🌡️ Cooling & Heating for Year-Round Comfort

The AUC-18HR4SAA1 is not limited to cooling. Its heating and cooling capability makes it suitable for Kenya’s varying indoor climate requirements.

Use cooling mode when indoor temperatures rise and heating mode when additional warmth is required.

This makes the unit a versatile option for offices, hospitality spaces, meeting rooms and other environments requiring year-round temperature management.
