Argo Apollo 12 HP Air Conditioner without Outdoor Unit
2.4 kW for cooling and heating rooms up to approx. 70 m³
The Argo Apollo 12 HP is a permanently installed air conditioner without an outdoor unit for cooling, heating, dehumidifying, and ventilating. This compact monoblock air conditioner is mounted directly onto an exterior wall and does not require a separate outdoor unit. With a cooling capacity of 2.4 kW, a heat pump function, DC inverter technology, and Wi-Fi control, the unit is particularly suitable for hotel rooms, offices, bedrooms, as well as containers, classrooms, and other temporary or permanent spaces.
The Argo Apollo 12 HP air conditioner is an attractive solution when a classic split air conditioning system with an outdoor unit is undesirable or not feasible. All components are housed in a single compact device. However, the installation requires two core drill holes through the exterior wall to draw in outside air and vent the warm air—or cold air during heating mode—to the outside.
Air conditioner without an outdoor unit:
The Argo Apollo 12 HP does not require a separate outdoor unit. Only two wall openings are necessary for air exchange. As a result, the exterior view remains relatively unobtrusive, and there is no need to mount a classic split-system outdoor unit on the facade.

Air conditioner without outdoor unit for 70 m³
The Argo Apollo 12 HP is designed for rooms with a volume of up to approximately 70 m³. The actual suitability depends on factors such as room temperature, insulation, window surface area, sun exposure, and the existing thermal load.
With a cooling capacity of 2.4 kW or 8530 BTU/h, the device provides sufficient power for numerous small to medium-sized rooms. Its design is particularly appealing for rooms where a separate outdoor unit is not desired for visual or structural reasons.
Suitable areas of use:
Hotel rooms, bedrooms, offices, containers, classrooms, temporary construction sites, and other spaces where a compact air conditioner without a separate outdoor unit is required.
Installation on the exterior wall
The Argo Apollo 12 HP is mounted directly onto a suitable exterior wall. On the back of the unit are the openings for supply and exhaust air. This allows the necessary outside air to be drawn in and the warm air generated during cooling operation to be vented outside.
For this reason, two core drill holes through the exterior wall are required for installation. The position and sizing of the wall openings must be carried out according to the specifications in the installation manual.
In heating mode, the heat pump process is reversed. This allows the unit to heat rooms with a heating capacity of up to 2.4 kW.
Important during planning:
With the Argo Apollo 12 HP, "without an outdoor unit" does not mean "without a wall penetration." For proper operation, two suitable openings in the exterior wall are required. Installation should be performed professionally according to the manufacturer's instructions.
Cooling and heating with heat pump technology
The Argo Apollo 12 HP can not only cool but also heat. The integrated heat pump technology enables a heating output of up to 2.4 kW.
You can choose between the different operating modes via the control panel, remote control, or Wi-Fi. This allows the unit to be used flexibly depending on the season.
| Mode |
Function |
| Cooling |
Reduces room temperature during warm days. |
| Heating |
Heat pump operation to warm the room. |
| Dehumidifying |
Removes moisture from the room air. |
| Ventilating |
Circulates room air without active cooling or heating. |
DC inverter technology for efficient operation
The Argo Apollo 12 HP works with modern DC inverter technology. The system's output is adjusted according to demand rather than running continuously at a fixed capacity.
This can contribute to a more consistent room climate and reduce unnecessary load changes. At the same time, the inverter technology enables comfortable and relatively quiet operation for an air conditioner of this type.
Wi-Fi control via smartphone and tablet
The Argo Apollo 12 HP can be operated directly on the device or conveniently via Wi-Fi. The air conditioner can be controlled from a smartphone or tablet using the corresponding app.
This allows you to adjust the mode, temperature, and other functions comfortably from a distance. This is especially practical if the device is used in a hotel room, office, or bedroom.
Comfort functions for daily operation
The Argo Apollo 12 HP features various automatic programs that allow the operation to be adapted to different situations.
-
Eco mode: supports consumption-oriented operation.
-
Turbo mode: allows for a rapid approach to the desired room temperature.
-
Sleep mode: adjusts operation for nighttime hours.
-
Anti-cold-wind: prevents the immediate discharge of air that has not yet been sufficiently heated during heating mode.
-
Self-diagnosis: errors are displayed on the screen to facilitate troubleshooting.
-
24-hour timer: start and stop times can be programmed.
Optimal air distribution with swing function
The air deflector, or flap, can be swiveled automatically or set individually to the desired position. This allows the direction of the airflow to be adapted to the specific room situation.
The automatic swiveling movement supports a more even distribution of conditioned air in the room. Alternatively, the position of the air deflector can be set manually.
Dehumidification with up to 24 liters per day
In addition to cooling and heating, the Argo Apollo 12 HP can also be used for dehumidification. The specified dehumidification capacity is up to 24 liters per 24 hours.
The actual dehumidification performance depends—as is standard for air conditioners—on the respective operating conditions and the room air.
Condensate drainage
Depending on the installation situation, the condensate generated during operation can be drained to the outside or inside via a corresponding line. The specific implementation of the condensate drain must be taken into account when planning the installation.
Unobtrusive alternative to split air conditioning
A major advantage of the air conditioner without an outdoor unit is its compact design. Unlike a classic split air conditioning system, no separate outdoor unit is required on the facade.
This makes the Argo Apollo 12 HP particularly interesting for buildings and rooms where an outdoor unit is not desired due to space, visual, or structural reasons.
At the same time, it must be noted that two wall openings are required. Therefore, the device is especially interesting when a permanent or semi-permanent installation without an outdoor unit is sought.
